stainless steel pipe stock

Why are Linkun alloy stainless steel pipes brighter than others?

The answer is very simple: the main reason why Linkun alloy stainless steel pipe looks bright is the material.

Everyone knows that in production-oriented enterprises, the first thing that determines product quality is raw materials, followed by quality standards and production processes.

The production processes are basically the same, and the difference is not very big. The reason for such a big gap is mainly due to different raw materials and quality standards.

The raw material steel strips for stainless steel pipes are divided into refining furnace steel strips and intermediate frequency furnace steel strips. Linkun Alloy Stainless Steel uses refining furnace steel strips, which have high and stable contents of various important trace elements. The surface of the refining furnace steel strip is smooth, free of trachoma and pitting, and has a certain brightness before polishing. On the contrary, there are many trachomas on the surface of the intermediate frequency furnace steel strip, the overall board surface is white, the polishing effect is poor, and the board surface is blurred.

The principle of polishing equipment lies in the high-speed operation and friction waxing of multiple sets of hemp wheels. The hemp wheel rubs against the surface of the stainless steel pipe at high speed and the best polishing effect can be achieved when it is completely attached. The hemp wheels made of inferior materials have poor adhesion and cannot achieve complete adhesion.

The difference in polishing wax materials is also a factor that affects the final brightness. A good polishing wax has fewer impurities, which not only makes the surface of the stainless steel decorative tube bright but also protects the surface of the stainless steel decorative tube from being scratched. During polishing, our highly skilled polishing masters use the finest polishing wax, and the brightness of the thrown tubes is the highest in the industry.

In addition, the quality standards are different. Linkun alloy stainless steel has very high requirements for brightness quality inspection. The brightness of each lkalloy pipe can reach more than 500 candelas.

When users don’t know how to choose stainless steel pipes, they compare lkalloy pipes with pipes from other brands. Users will like lkalloy stainless steel pipes at a glance.

9 things to note when welding Hastelloy C-276

Hastelloy C-276, UNS N10276, referred to as C276, is one of the most common nickel-based corrosion-resistant alloys. It is suitable for various chemical industries containing oxidizing and reducing media. The higher molybdenum and chromium content makes the alloy resistant to chlorine. Ion corrosion and tungsten elements further improve corrosion resistance.

Hastelloy C-276 is one of the only materials resistant to corrosion by moist chlorine, hypochlorite, and chlorine dioxide solutions. It has significant resistance to high-concentration chloride solutions such as ferric chloride and copper chloride. Corrosion resistance.

Hastelloy C-276 can be used in the following application areas

1. Pollution control stack liners, ducts, dampers, scrubbers, stack gas reheaters, fans and fan shrouds

2. Flue gas desulfurization system

3. Chemical processing components such as heat exchangers, reaction vessels, evaporators, and delivery pipes

4. Sulfur gas wells

5. Pulp and paper production

6. Waste disposal

7. Pharmaceutical and food processing equipment

There are 9 major precautions when welding Hastelloy C-276:

1. Cleaning before welding
Since dirt and oxides adhere to the surface of Hastelloy, the welding area must be cleaned before welding. The cleaning method can be mechanical cleaning, that is, using an angle grinder to polish the welding area until the metallic luster is exposed. The width of the cleaning should be more than 100mm to ensure that impurities do not enter the welding area.

2. Welding method
When welding, the direct current connection method is generally used for welding. When the direct current connection is used, the temperature of the tungsten grade is low, the allowable current is large, and the loss of the tungsten grade is small. The end of the tungsten grade is ground to 30°, and the head is slightly ground out.

3. Gas protection
Hastelloy C-276 must take measures to minimize the decrease in corrosion resistance of the weld and heat affected zone, such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), submerged arc welding, or some other welding method that can minimize the decrease in corrosion resistance of welds and heat-affected zones.

“Special Steel 100 Seconds” considers that the argon gas protection effect is obvious: good protection, concentrated heat, good weld quality, small heat-affected zone, small deformation of the weldment, minimizing the decrease in the corrosion resistance of the weld and heat-affected zone.

4. Practical training
It is best to use mechanical processing or cold processing for welding grooves to ensure that the shape, size, and roughness of the processed surface comply with the drawing requirements or the welding process regulations. Mechanical processing of the groove before welding will cause work hardening, so it is necessary to grind the machined groove before welding. Welding grooves should not have defects such as delamination, folding, cracks, and tears.

Polish the metal surface within the welding groove and the 50mm width on both sides to remove the oxidation color, and clean it with oxide-free solvents such as ethanol, acetone, or propanol to remove grease, moisture, chalk marks, and other contaminants. The painting solvent should be Caiying Clean Use lint-free leather or cellulose sponge. “Special Steel 100 Seconds” reminds us that useless welding materials and harmful substances on workers’ unclean clothes and shoes should be prevented from coming into contact with the workpiece to avoid contamination of the workpiece.

5. Welding material selection
Recommendation: Use ERNiCrMo-4 welding wire and ENiCrMo-4 as the welding rod. This kind of welding wire has excellent corrosion resistance and process performance. Its chemical composition is similar to that of the base metal and its manganese content is higher than that of the base metal. It can improve crack resistance and control porosity during welding. The particularly ultra-low carbon serves to prevent the risk of intergranular corrosion.

6. Preheating and interlayer temperature
Hastelloy welding at room temperature generally does not require preheating. Only when the temperature in the air is below zero or moisture accumulates, the base metal needs to be heated, but the heating temperature only needs to reach 30-40°C.

During the welding process, the weld metal will form a Fe-Cr metal compound, namely σ phase, at high temperature (375-875) for a long time. The σ phase is extremely hard and brittle and is distributed at the grain boundaries, causing The impact toughness of the weld metal to decrease and become embrittled.

When using multi-layer welding, the interlayer temperature must be lower than 90°C to prevent excessive length of 375-875°C from causing σ phase embrittlement.

7. Precautions when welding
To reduce the welding heat input, try to use a small welding current and a fast welding method for welding. In addition, since Hastelloy is easy to crack at the arc closing position, the arc crater must be filled when the arc closes. Before starting arc welding again, the previous arc crater must be polished, and then cleaned with a soft brush before proceeding. Subsequent welding. These two treatments can inhibit the occurrence of thermal cracks.

Welded joints are susceptible to intergranular corrosion. Including intergranular corrosion of welds, “knife corrosion” in the superheated zone close to the fusion line, and intergranular corrosion at the sensitizing temperature of the heat-affected zone.

8. Post-weld heat treatment
However, in very harsh environments, C-276 materials and weldments must undergo solution heat treatment to obtain the best corrosion resistance.

Hastelloy C-276 alloy material solid solution heat treatment, “special steel 100 seconds” is considered to include two processes: (1) heating at 1040~1150; (2) rapid cooling to a black state (around 400) within two minutes, The material treated in this way has good corrosion resistance. Therefore, it is ineffective to only perform stress relief heat treatment on Hastelloy C-276 alloy. Before heat treatment, it is necessary to clean the surface of the alloy from oil stains and other dirt that may produce carbon elements during the heat treatment process.

The surface of Hastelloy C-276 alloy will produce oxides during welding or heat treatment, which will reduce the Cr content in the alloy and affect the corrosion resistance, so the surface must be cleaned. You can use a stainless steel wire brush or grinding wheel, then immerse in a mixture of nitric acid and hydrofluoric acid in an appropriate proportion for pickling, and finally rinse with clean water.

9. Precautions for welding tools
Processing tools should be special cleaning tools for nickel alloys. These tools should be stored separately and marked to prevent confusion with other tools.

Care should be taken to prevent the workpiece from contacting metals with low melting points to avoid the embrittlement of unstable metals caused by the increase in carbon or sulfur. The use of thermometer chalk, ink, and grease should also be restricted during the manufacturing process.

The grinding wheel used for grinding the workpiece should be iron-free, and the adhesive should not be organic resin.

The equipment positioning of pressure welding parts before welding should be performed using the same process as the qualified formal welding, and the positioning weld should finally be melted into the permanent weld. Welding parts are not allowed to be forced to assemble to cause local hardening of the welding parts.

Advantages and Disadvantages of Brushed Stainless Steel Pipe and Mirror Stainless Steel Pipe

Brushed stainless steel pipe has a silk-like texture on the surface of stainless steel, which is just a processing technology of stainless steel. The surface is matte, with a trace of texture on it, but it cannot be touched. It is more wear-resistant than bright stainless steel pipes. The wire drawing process will lose the thickness of the stainless steel pipe to a certain extent, generally 0.1~0.2mm. In addition, since palms contain oil and sweat, brushed stainless steel pipes will leave obvious fingerprints when touched frequently and require regular scrubbing.

the price of Brushed Stainless Steel Pipe

Mirror stainless steel pipe is a stainless steel pipe that is polished on the surface of the pipe through polishing equipment, making the pipe as smooth and beautiful as a mirror. Mirror stainless steel pipe products are widely used in construction projects, building materials decoration, protective railing projects, etc.

In short, the application scenarios of brushed stainless steel pipes and mirror stainless steel pipes are the same. Brushed stainless steel pipe has a rough surface. The 8K mirror stainless steel pipe has a smooth surface like a mirror. Brushed stainless steel is produced by grinding with a grinding wheel, which is relatively simple. The surface protective layer is somewhat damaged after drawing, so the surface of the mirror stainless steel pipe is intact and more durable.

What are the methods to improve the surface processing quality of titanium alloy?

What are the methods to improve the surface processing quality of titanium alloy?

1. Choose the right cutting tool

The difficulty of processing titanium alloy is largely related to the characteristics of its material. Its low thermal conductivity, high strength, and low plasticity will all have a certain impact on the cutting process. Therefore, selecting appropriate cutting tools is crucial to improving the quality of titanium alloy surface processing. Some tools specifically for titanium alloy processing, such as the angle of the cutting edge, the material of the tool head, etc., need to be considered.

2. Reasonable control of process parameters

For titanium alloy surface processing, different process parameters will also have different effects on the processing quality. Reasonable control of parameters such as processing speed, cutting speed, and cutting depth can effectively reduce surface roughness and improve the quality of titanium alloy surface processing.

3. Ensure processing lubrication conditions

The machining process of titanium alloys requires good lubrication conditions, otherwise, it will easily lead to overheating of the cutting tools, surface damage, etc., thus affecting the processing quality. Therefore, it is very important to choose the appropriate cutting fluid and reasonably control the machining lubrication conditions.

4. Pay attention to problems during processing

In addition to the above factors, special attention needs to be paid to some issues during processing. For example, improper surface treatment, chatter, vibration, and other problems during processing may affect the quality of titanium alloy surface processing. Therefore, attention to detail is required during processing to avoid these problems.

In summary, the key to improving the surface processing quality of titanium alloys is to comprehensively consider cutting tools, process parameters, lubrication conditions, and other factors, and pay special attention to some details during the processing process. Only by considering these aspects can the quality of titanium alloy surface processing be effectively improved.

Study on the influence of precision steel pipe manufacturing process on material properties.

Research on the influence of precision steel pipe manufacturing process on material properties

precision steel pipe supplier

As a high-quality pipe, precision steel pipe is widely used in the petroleum, chemical industry, electric power, machinery, aerospace, and other fields. Its manufacturing process has a crucial impact on material performance, which is directly related to product quality and reliability. This article will conduct in-depth research and analysis on the impact of the manufacturing process of precision steel pipes on material properties.

The Manufacturing process of precision steel pipes
The manufacturing processes of precision steel pipes mainly include hot rolling and cold rolling. Hot rolling refers to rolling steel pipes at high temperatures to deform them and obtain the desired shape and size. Cold rolling rolls steel pipes at room temperature to obtain more precise dimensions and a smoother surface. During the manufacturing process, the steel pipe also needs to be straightened, annealed, quenched, tempered, and other treatments to further improve its performance.

The influence of the manufacturing process on material properties
1. Influence of hot rolling process
The hot rolling process has a significant impact on the material properties of precision steel pipes. When rolling at high temperatures, the grains inside the steel pipe will deform, thereby refining the grains and improving the strength and toughness of the material. At the same time, the work-hardening effect produced during the hot rolling process can improve the hardness and wear resistance of the steel pipe. However, the selection of hot rolling temperature and time must be appropriate, otherwise defects such as cracks and holes will appear inside the steel pipe, seriously affecting its performance.

2. Influence of cold rolling process
Compared with hot rolling, the cold rolling process has less impact on the material properties of precision steel pipes. When rolling at room temperature, the grains inside the steel pipe will not undergo significant deformation, so there will be no work-hardening effect. However, cold rolling can precisely control the size and shape of steel pipes, improving their accuracy and surface quality. At the same time, proper cold rolling can improve the coercive force and magnetic permeability of steel pipes, making it more suitable for manufacturing high-precision, high-performance magnetic components.

3. Influence of annealing process
Annealing is an important link in the manufacturing process of precision steel pipes. Its main purpose is to eliminate the internal stress generated during the rolling process and make the internal structure of the steel pipe more uniform and stable. The control of annealing temperature and time has a great influence on the performance of precision steel pipes. If the annealing temperature is too high or the time is too long, the grains inside the steel pipe will grow, reducing its strength and toughness; if the annealing temperature is too low or the time is too short, the internal stress cannot be eliminated and the steel pipe will be damaged during subsequent processing and use. Problems such as deformation and cracking may easily occur.

4. Influence of quenching and tempering processes
Quenching is a process in which the steel pipe is heated above the critical temperature and then rapidly cooled to obtain a martensite structure. Tempering is reheating the quenched steel pipe to a certain temperature and keeping it warm for a certain period to stabilize the organizational structure and eliminate internal stress. The quenching and tempering process has a great impact on the performance of precision steel pipes. The control of quenching temperature and time determines the quantity and distribution of martensite, thereby affecting the hardness and strength of the steel pipe; the control of tempering temperature and time determines the stability and toughness of the organizational structure. Proper quenching and tempering processes can make precision steel pipes have good toughness and durability while maintaining high hardness and strength.

3. Conclusion
The manufacturing process of precision steel pipes has a significant impact on their material properties. Reasonable manufacturing processes can make precision steel pipes have good strength, toughness, hardness, durability, and other properties to meet various complex and high-demand application scenarios. To obtain better material properties, it is necessary to continuously optimize manufacturing process parameters, strengthen quality control and testing, and improve production efficiency and product quality. At the same time, it is also necessary to strengthen basic research and gain an in-depth understanding of the intrinsic connections and laws between the manufacturing process and material properties of precision steel pipes, to provide strong support for promoting the sustainable development of the precision steel pipe industry.

Welding quality inspection

Welding quality inspection – sealing inspection

Welding quality testing refers to the testing of welding results, to ensure the integrity, reliability, safety, and usability of the welded structure. In addition to the requirements for welding technology and welding processes, welding quality inspection is also an important part of welded structure quality management.

Let’s talk about the welding quality inspection method: sealing inspection.

So how to test the tightness of welded joints?

In general, the following methods can be used for detection:

1. Submersion test

Used for small containers or pipes subject to small internal pressure. Before the inspection, first, fill the container or pipe with compressed air at a certain pressure (0.4-0.5MPa), and then submerge it in water to check the sealing. If there is leakage, there must be bubbles in the water. This is also a common method for checking whether bicycle inner tubes are leaking.

2. Water test

Use the static pressure generated by the weight of water to check whether there are leaks in the structure. Mainly based on visual inspection, it is suitable for general welded structures that are not under pressure but require sealing.

3. Ammonia leakage test

The purpose is the same as the coal pump leakage test, and its sensitivity is higher than the kerosene leakage test. Before the test, first paste a white paper strip or bandage soaked in 5% mass fraction of HgNO3, aqueous solution, or phenolphthalein reagent on the side of the weld for easy observation, and then fill the container with ammonia or add 1% volume fraction of compressed nitrogen. Air.

If there is leakage, stains will appear on the white paper strip or bandage. Those soaked in 5% HgNO3 aqueous solution are black spots, and those soaked in phenolphthalein reagent are red spots.

4. Kerosene leakage test

It is used for welded structures subject to small internal pressure and requiring a certain degree of sealing. Kerosene has strong permeability and is very suitable for sealing inspection of welds. Before inspection, first brush lime water on one side of the weld for easy observation, and then brush kerosene on the other side of the weld. If there are penetrating defects, kerosene spots or kerosene bands will appear on the lime layer. The observation time is 15-30min.

Welding quality inspection

5. Helium mass spectrometry test

The helium mass spectrometer test is currently the most effective means of sealing testing. The helium mass spectrometer is extremely sensitive and can detect helium with a volume fraction of 10-6. Before the test, the container is filled with helium, and then leaks are detected outside the weld of the container. The disadvantages are that helium is expensive and the inspection cycle is long.

Although helium has extremely strong penetrating power, it still takes a long time to penetrate extremely small gaps (such gaps cannot be detected by other means), and the leak detection of some thick-walled containers often takes dozens of hours. Appropriate heating can speed up leak detection.

6. Air tightness test

The Air tightness test is a routine inspection method for boilers, pressure vessels, and other important welded structures that require air tightness. The medium is clean air, and the test pressure is generally equal to the design pressure. The pressure should be increased step by step during the test.

After reaching the design pressure, apply soapy water on the outside of the weld or sealing surface and check whether the soapy water bubbles. Because there is a risk of explosion in the air tightness test, it should be carried out after the hydraulic pressure test is passed.

The air tightness test is different from the air pressure test:

1. Its purpose is different. The air tightness test is to test the tightness of the pressure vessel, and the air pressure test is to test the pressure resistance strength of the pressure vessel. Secondly, the test pressures are different. The air tightness test pressure is the design pressure of the container, and the air pressure test pressure is 1.15 times the design pressure.

The air pressure test is mainly to test the strength and sealing of the equipment, and the air tightness test is mainly to check the tightness of the equipment, especially small penetrating defects; the air tightness test focuses more on whether the equipment has small leaks, and the air pressure test focuses on to the overall strength of the equipment.

2. Use media

Air is generally used in the actual operation of the air pressure test. In addition to air, the air tightness test uses ammonia, halogen, or helium if the medium is highly toxic and does not allow leakage or is easy to penetrate.

3. Safety accessories

During the air pressure test, there is no need to install safety accessories on the equipment; the air tightness test can generally be performed after the safety accessories are installed (capacity regulations).

4. Sequence

The air tightness test needs to be carried out after the air pressure or water pressure test is completed.

5. Test pressure

The air pressure test pressure is 1.15 times the design pressure, and the internal pressure equipment needs to be multiplied by the temperature trimming coefficient; when the air tightness test medium is air, the test pressure is the design pressure. If other media are used, it should be adjusted according to the medium conditions.

6. Usage occasions

Pneumatic test: A Hydraulic test is preferred. If the hydraulic test cannot be used due to equipment structure or support reasons, or when the equipment volume is large, the pneumatic test is generally used. Air tightness test: The medium is a highly or extremely hazardous medium, or no leakage is allowed.

The air pressure test is a pressure test, which is used to check the pressure-bearing strength of the equipment. The air tightness test is a tightness test, which is used to test the sealing performance of the equipment.

stainless steel engineering pipe supplier

1. Welding connection

Welding is the most commonly used method for connecting stainless steel pipes. It can achieve strong connections with high load-bearing capacity and corrosion resistance. The welded connections of stainless steel pipes can be divided into two types: manual welding and automated welding. Manual welding is suitable for small projects or special-shaped pipe connections, while automated welding is suitable for large projects and highly repetitive pipe connections.

When welding stainless steel pipes, you need to pay attention to the following points: First, choose the appropriate welding method. Common ones include TIG welding, MIG welding, electric welding, etc. Secondly, ensure the cleanliness of the welding surface to avoid the presence of dust, dirt, and other impurities. Finally, appropriate preheating and adjustment of welding parameters should be carried out before welding to ensure welding quality and connection strength.

2. Threaded connection

A threaded connection is a simple and reliable way to connect stainless steel pipes. It is suitable for engineering projects with smaller pipe diameters and lower pressures. Stainless steel pipe thread connections are divided into two types: internal threads and external threads. Common thread connection standards include the internationally accepted Willai thread, the commonly used domestic tapered pipe thread, etc.

When making threaded connections for stainless steel pipes, you need to pay attention to the following points: First, the sealing of threaded connections is poor, so sealants or gaskets need to be used to seal them to prevent water leakage. Secondly, the threaded connection must be installed with moderate attention, neither too loose to cause leakage nor too tight to cause deformation. Finally, be careful when disassembling to avoid damaging or straining the threads.

3. Pressure connection

Pressure connection is a method of connecting stainless steel pipes through pre-pressurization. It is suitable for projects with larger pipe diameters and higher pressures. There are two main types of pressure connections for stainless steel pipes: socket connections and flange connections. The socket connection is to inserts the pipe into the connection port and seals it under pressure, while the flange connection is to connects the pipes through flanges and bolts.

When making pressure connections of stainless steel pipes, you need to pay attention to the following points: First, choose appropriate sealing materials. Common ones include rubber gaskets, PTFE gaskets, etc. Secondly, the installation requirements must be strictly followed to ensure the sealing and safety of the connection. Finally, testing should be performed before connection to ensure the reliability and voltage resistance of the connection.

To sum up, stainless steel pipe connection technology is an important link in ensuring project quality and service life. Whether it is a welded connection, a threaded connection, or a pressure connection, it needs to be operated by the correct methods and requirements. Choosing the appropriate connection method can not only ensure the stability and durability of the project but also improve work efficiency and safety. I hope this article is helpful to your engineering projects!
