Stainless steel round tube production process and characteristics

Stainless steel round tube is a kind of stainless steel material hollow round pipe, widely studied and applied in building decoration design decoration, the metal processing technology industry. For general use of stainless steel material round tube, the main technical parameters are stainless steel round tube material, stainless steel round tube diameter, stainless steel round tube length, stainless steel tube wall thickness, and so on.

Stainless steel tubes can be divided into round tubes and profiled tubes according to the shape of the section. The shaped tube has a rectangular tube, rhombic tube, oval tube, hexagonal tube, octagonal tube, and various asymmetric tubes with different cross sections. The shaped tube is widely researched and applied to various structural components, tools, and mechanical design parts in enterprises. Compared with the round tube structure, the shaped tube has a greater impact on the moment of inertia and the effective modulus of the cross-section, with the advantages of bending resistance and torsion resistance.

What are the classifications of stainless steel round tubes？
Stainless steel round tubes according to use can be divided into decorative stainless steel round tubes, industrial stainless steel round tubes, sanitary stainless steel round tube

Stainless steel material round tubes according to the production technology process can be divided into seamless tubes and welded tubes. Seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, and extruded pipe, etc., cold-drawn, and cold-rolled is the secondary processing of steel pipe; welded pipe is divided into straight seam welded pipe and spiral welded pipe.

Stainless steel material round tubes according to different materials can be divided into 201 stainless steel or round tubes, 304 stainless steel using round tubes, 316L stainless steel round tubes, and so on.

A stainless steel round tube is how to process out？
Stainless steel welded pipe production process: raw materials – slitting – welded tube – heat treatment – straightening – straightening – end repair – pickling – water pressure test – inspection (spray printing) – packaging – shipping

Cold-drawn (rolled) seamless steel pipe: round billet→heating→piercing→heading→annealing→acid washing→oil coating (copper plating)→multiple cold-drawn (cold-rolled)→billet→heat treatment→straightening→hydraulic test (flaw detection)→marking→warehousing.
Hot rolled (extruded seamless steel pipe): round billet → heating → piercing → three-roll inclined rolling, continuous rolling or extrusion → stripping → sizing (or reduction) → cooling → billet pipe → straightening → hydrostatic test (or flaw detection) → marking → storage.

What are the characteristics of stainless steel round pipes?
From the above process design flow, it is not difficult to see: First, the enterprise products for continuous online production, the thicker the wall thickness, the greater the unit and dissolution equipment and investment risk, the lower the economy and practicality. Thinner wall thickness, its input work output ratio will carry out the corresponding ability to decline; Secondly, the product of the process research to determine its advantages and disadvantages, generally using welded steel pipe with high precision, wall thickness uniformity, to stainless steel tube inside surface brightness (steel plate material surface brightness control level development decision) and any one length. Therefore, it shows its economy and aesthetics in carrying out high precision as well as low-pressure working fluid applications.

From the above processing can be clearly seen in a process: first, the wall thickness of the product, the more economical development of practical, thinner wall thickness, processing business costs will increase substantially; second, the product process research determines its limitations, general low precision seamless steel tube: uneven thickness distribution, bright tube long low-cost high appearance, and the internal and external pitting of the surface and the black spot is not easy to remove; Plastic As the third inspection, must have offline data processing. Therefore, high pressure, high strength, mechanical structure, and so on show superiority.

Stainless steel round tubes have their own different uses
Stainless steel tube is a practical and economical steel and is an important influence on the steel industry products. Widely used in social life for decoration and industry, many Chinese in the market enterprise production of stair handrails, windows, railings, furniture, and so on. Common 201 and 304 are two different materials. Stainless steel pipe is a kind of hollow cylindrical bar with many enterprises used to carry out decoration or piping systems to transport working fluids, such as stainless steel in buildings as well as handrails and pipelines conveying oil, gas, water, air, steam, is the application of stainless steel as a decorative pipe. In addition, under the same bending and plasticity conditions, light weight is one of its advantages, so it is widely used in the manufacture of mechanical parts and engineering structures.
