Thin-walled stainless steel tube refers to the ratio of wall thickness to diameter is not more than 6%, and the thin-walled stainless steel tube is a kind of steel pipe, normally, the wall thickness of 0.6 ~ 2.0mm stainless steel or stainless steel plate, with automatic welding and other welding process made of pipe. Mainly used for building water supply and direct drinking water pipes.
Thin-walled stainless steel tubing has the following outstanding advantages:
1, To meet the health requirements of thin-walled stainless steel tube will not cause secondary pollution of water quality, to meet the national direct drinking water quality standards.
2, Thin-walled stainless steel tube is a fully recyclable water pipe.
3, Thin-walled stainless steel tube material strength is higher than all the water pipe material, greatly reducing the water pipe by the impact of the possibility of external leakage, a lot of water conservation.
4, Thin-walled stainless steel tube corrosion resistance is superior, in the long-term use of the process will not scale, smooth inside the wall, transport energy consumption is low, cost savings, is the lowest cost of transport pipe material.
5, Thin-walled stainless steel tube material insulation performance is 24 times the copper material pipe, a large number of savings in the hot water transport in the geothermal energy loss.
Note:
Building water supply thin-walled stainless steel tube and pipe are chromium (Cr) in the amount of 12% or more, and as needed to add other metal elements formed by the austenitic crystal structure of ferroalloy. Adding nickel (Ni) can improve the ductility and toughness of the material, making the processing easy to shape, should be bent. Reduce the carbon (C) content, can improve the welding performance of materials. Addition of molybdenum (Mo) or manganese (Mn) and other content, can improve the resistance of the material pitting and corrosion resistance of the performance. Thin-walled stainless steel tube with chromium and oxygen, oxidant reaction, resulting in passivation, in the surface to form a thin and tough dense passivation film Cr2O3, from the role of corrosion-resistant protective film. Stainless steel pipe, pipe fittings if the miscellaneous, pickling, passivation process, can produce the thickness of Cr2O3 increased, dense uniformity enhanced; stainless steel tube by polishing, pipe by the polishing process, not only to eliminate surface defects, but also So that passivation film is more delicate, dense, in order to reduce the probability of point corrosion. At the same time, the pipe after the fine inner wall smooth, small friction, and further improve the hydraulic performance of the pipe, saving consumption.
