Application of stainless steel pipe



With the implementation of Chinas reform and opening up policy, the national economy has achieved rapid growth, urban housing, public buildings and tourism facilities are being built in large quantities, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality. Galvanized steel pipe, as a common pipe material, is easy to corrode. Under the influence of relevant national policies, galvanized steel pipe will gradually withdraw from the historical stage. Plastic pipe, composite pipe and copper pipe have become the common pipe materials of pipeline system. However, in many cases, the stainless steel pipe has more advantages, especially the thin-walled stainless steel pipe with wall thickness of 0.6-1.2mm has the characteristics of safety, reliability, environmental protection, economy and applicability in high-quality drinking water system, hot water system and water supply system which puts safety and sanitation in the first place. It has been proved by engineering practice at home and abroad that it is one of the best, new, energy-saving and environmental protection pipes for water supply system. It is also a kind of competitive water supply pipe material, which will play an incomparable role in improving water quality and peoples living standard.



In the building water supply pipe system, because the galvanized steel pipe has ended the glorious history of one hundred years, all kinds of new plastic pipe and composite pipe have been developed rapidly. However, there are still some deficiencies in various kinds of pipe, which can not fully meet the needs of water supply pipe system and the national requirements for drinking water and related water quality. Therefore, relevant experts predict: building water supply pipe will eventually return to the era of metal pipe. According to the application experience of foreign countries, the thin-walled stainless steel pipe is regarded as one of the best comprehensive properties among metal pipes.
