First, the small diameter 304 stainless steel welded pipe is continuously produced online. The thicker the wall thickness, the greater the investment in the unit and the welding equipment, the less economic and practical it is. The thinner the wall thickness, the lower its input-output ratio will be;
Second, the product's technology determines its advantages and disadvantages, generally 304 stainless steel welded pipe with high accuracy, uniform wall thickness, high brightness inside and outside the pipe (surface brightness of the steel pipe determined by the surface grade of the steel plate), can be arbitrarily determined. Therefore, it reflects its economy and aesthetics in the application of high precision, medium and low pressure fluids.
GB / T12770-2002 (stainless steel welded steel pipe for mechanical structure). Mainly used in machinery, automobiles, bicycles, furniture, hotel and restaurant decoration and other mechanical parts and structural parts. Its representative materials are 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.
GB / T12771-2008 (stainless steel welded steel pipe for fluid transportation). Mainly used to transport low-pressure corrosive media. Representative materials are 06Cr19Ni10, 022Cr19Ni10, 06Cr19Ni110Ti, 00Cr17, 0Cr18Ni11Nb, 06Cr17Ni12Mo2 and so on.
