Stainless Steel Seamless Pipe is one of our more common seamless pipes, so where is the stainless steel seamless pipe used? What is the performance?
In the building water supply piping system, as the galvanized steel pipe has ended a hundred years of glorious history, various new plastic pipes and composite pipes have been developed rapidly, but various pipes still have some shortcomings to varying degrees, which are far from being fully adapted to water supply pipe Department’s needs and the country’s requirements for drinking water and related water quality. Therefore, relevant experts predict: Building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, a thin-walled stainless steel pipe is recognized as one of the pipes with the best comprehensive performance among the metal pipes.
As the stainless steel seamless pipe is used as a reprocessing device, to control the chromium-carbon compound in the welding affected part as much as possible, the carbon content is reduced, or the content of silicon and phosphorus is limited in 310Nb steel. In addition, in 304ULC steel, to improve the corrosion resistance in nitric acid, the steel industry with a phosphorus content of 0.015% or less is strongly restricted. After repeated 20 times of 65% boiling nitric acid corrosion test, it is found that if the corrosion rate of the solution-treated material is below 0.1mm/a, the sensitized material at 650℃×2h is below 0.2mm/a. , Has excellent corrosiveness. yintuosteel.com
