The stainless steel pipe installed in the bathroom will have some requirements on material selection, corrosion resistance, heat resistance, etc. So what are the quality requirements for these stainless steel pipes?
1. Selection of raw materials
According to the provisions of JG/T 427-2014, the stainless steel pipe materials should be 06Cr19Ni10 (S30408), 022Cr19Ni10 (S30403), 06Cr17Ni12Mo2 (S31608), 022Cr17Ni12Mo2 (S31603) specified in GB/T 20878.
2. Appearance of the product
The surface of the sanitary pipe should be free from pits, scratches, pores, burrs, sink marks, holes, cold insulation, sand holes, ripples, warping and other defects; the texture of the polished surface should be clear, consistent, and free of random lines; the color of the coating surface Uniform and consistent, no defects such as bubble sagging, falling off, paint buildup, orange peel, etc; Moreover, there should be no sharp corners, burrs, burrs and other appearance defects that may cause harm to the human body in the easily accessible parts of the human body.
3. Corrosion resistance
Most stainless steel pipes require good corrosion resistance. Due to the relatively humid environment, salt spray test will be used to observe whether the requirements are met.
4. Polishing performance
Stainless steel pipe for bathroom – handrail
Stainless steel pipes are generally polished during production. The surface of the product is clean and textured, which is very in line with the aesthetic needs of consumers. Polishing has requirements on material surface, material hardness, etc. If the surface of the material has scratches, pitting, over-pickling and other problems, it will affect the polishing performance of the product tube; the hardness of the material is too low, and it is not easy to polish when polishing, and the surface is prone to orange peel phenomenon during deep drawing, so the hardness of the material is high. , the polishing performance is relatively good.
The above are some of the requirements for stainless steel pipes for sanitary ware that Xiaobian has compiled for you. I hope it can be helpful to you. See you in the next issue!
