With the implementation of China’s reform and opening-up policy, the national economy has gained rapid growth, and a large number of town houses, public buildings and tourism facilities have been built, putting forward new requirements for hot water supply and domestic water supply. Especially the water quality issue, people pay more and more attention to it, and the requirements have been increasing. Galvanized steel pipe, a common pipe because of its easy corrosive, under the influence of relevant national policies, will gradually withdraw from the historical stage, plastic pipe, composite pipe and copper pipe into the common pipe of the piping system. But in many cases, stainless steel pipe is more superior, especially the wall thickness of only 0.6 ~ 1.2mm thin-walled stainless steel pipe in the drinking water system, hot water system and will be safe, sanitary water supply system in the first place, with safe and reliable, health and environmental protection, economic and other characteristics. Has been proven by domestic and foreign engineering practice is a good comprehensive performance of the water supply system, new, energy-saving and environmentally friendly pipe, is also a very competitive water supply pipe material, will play an incomparable role in improving water quality, improve people’s living standards.
In the building water supply system, as galvanized steel pipe has ended a hundred years of glorious history, a variety of new plastic pipes and composite pipes have been rapidly developed, but a variety of pipes still have some shortcomings to varying degrees, far from fully adapt to the needs of the water supply system and the country’s requirements for drinking water and related water quality. Therefore, the prediction: the building water supply pipe material will eventually return to the era of metal pipe. According to foreign application experience, in the metal pipe identified thin-walled stainless steel pipe for a good overall performance of one of the pipe.
Domestic thin-walled stainless steel pipe has been ripe for promotion and application
Thin-walled stainless steel pipe, domestic production and use in the late 1990s, is the emerging new family in the field of pipe, has been used in large quantities in the building water supply and direct drinking water pipeline.
Thin-walled stainless steel pipe durable, has been recognized by the engineering community, and the relevant parties are reducing the wall thickness, reduce prices to facilitate further promotion. In particular, the small-diameter stainless steel pipe price is not high, so the supporting connection method, the reliability of the fittings and price is the main factor in determining its development. Domestic developers in Sichuan, Guangdong, Zhejiang, Jiangsu and other places have developed their own connection technology and fittings, is a very promising pipe development. The Ministry of Construction and related departments also attach great importance to this new pipe, according to China Technology Market Management Promotion Center, State Science and Technology City word [2001] No. 71 document, on the promotion and application of “high diameter wall ratio high-precision stainless steel water pipe and supporting fittings and special technology” notice was informed that the thin-walled stainless steel pipe technology and products The promotion of the application of modern architecture in China to improve the grade, improve and protect water quality are of great significance.
At the same time, the Ministry of Construction attaches great importance to the promotion and application of thin-walled stainless steel pipe. The industry standard of “thin-walled stainless steel water pipe” has been released in 2001 for implementation. Related pipeline engineering technical regulations and installation atlas, the Ministry of Construction has issued a document, is being prepared by Tongji University is responsible for. At present, Sichuan, Guangdong, Zhejiang, Jiangsu and other places have manufacturers to produce thin-walled stainless steel pipe, the product has tended to mature, and therefore, the time has come to promote the application.
Stainless steel pipe is safe, reliable, sanitary and environmentally friendly, economical, thin-walled pipes and new reliable, simple and convenient connection methods are developed successfully, so that it has more irreplaceable advantages of other pipes, the application of engineering will be more and more, the use of more and more popular, the prospects are good.
