The time for the promotion and application of domestic thin-walled stainless steel pipes is ripe

Thin-walled stainless steel pipes were produced and used only in the late 1990s in China. They are a newcomer in the field of pipe materials. They have been widely used in building water supply and direct drinking water pipelines. Thin-walled stainless steel pipes are durable and have been recognized by the engineering community, and the relevant parties are starting to reduce the wall thickness and lower the price to facilitate further promotion. Especially for small-caliber stainless steel pipes, the price is not high. Therefore, the matching connection method, the reliability of the pipe fittings and the price are the main factors that determine its development. Domestic developers in Sichuan, Guangdong, Zhejiang, Jiangsu and other places have independently developed connection technology and pipe fittings, which are promising pipes. The Ministry of Construction and related departments also attach great importance to this new type of pipe. According to the China Technology Market Management Promotion Center and the Guokeshizi [2001] No. 71 document, on the promotion and application of "high-diameter wall ratio high-precision stainless steel medium and high-pressure water supply pipes and supporting It was learned from the notice of "Pipe Fittings and Special Technology" that the popularization and application of thin-walled stainless steel pipe technology and products are of great significance to improving the quality of modern buildings in China and improving and ensuring the quality of water supply. At the same time, the Ministry of Construction attaches great importance to the promotion and application of thin-walled stainless steel pipes. The industry standard of "Thin-Wall Stainless Steel Water Pipe" was issued and implemented in 2001. The relevant pipeline engineering technical regulations and installation atlases have been issued by the Ministry of Construction and are being compiled by Tongji University. At present, there are professional manufacturers in Sichuan, Guangdong, Zhejiang, Jiangsu and other places to produce thin-walled stainless steel pipes. The products have matured. Therefore, the time for popularization and application has come.
