In building water distribution system, galvanized steel pipe has been over a hundred years glorious history and a variety of new plastic pipes and composite pipes have developed rapidly, but there are some deficiencies due to varying degrees, far from being able to fully meet the water supply pipe needs of the department and the state of drinking water and water quality requirements. Therefore, the experts predicted: the building water supply pipe will eventually be restored to the era of metal pipe. according to the application of foreign experience, wall stainless steel pipe for pipe is one of the best overall performance.
Domestic thin-walled 316 stainless steel tubes that promote the use of the time is ripe:
First, thin-walled stainless steel tube, the country began production in the late 1990s, the use of today’s pipe-and-coming in the field of newborn family have been widely used in building water supply and drinking water pipeline.
Second, the thin-walled stainless steel tube durable has been recognized by the engineering community, and the parties concerned are to reduce the wall thickness, reducing the price to proceed in order to facilitate further promotion. Especially small diameter stainless steel pipe, the price is not high, supporting the connection method, the pipe reliability and price are the main factors that determine its development. Domestic has been a developer in Sichuan, Guangdong, Zhejiang, Jiangsu and other places independently developed connection technology and pipe fittings, pipe promising.
With the implementation of China’s reform and opening-up policy, the national economy experienced rapid growth, urban housing, public buildings and tourist facilities to build a large number of new requirements on the hot water supply and domestic water supply. Water quality problems, there is growing attention, and are required to improve. Galvanized steel pipe is commonly used pipe because of its easy to corrosion under the influence of the relevant national policies, will gradually exit the stage of history, plastic pipe, composite pipe and copper pipe became the piping system used pipe.
However, in many cases, the stainless steel tube is more advantages, especially the wall thickness of only 0.6 ~ 1.2mm wall stainless steel pipe in high-quality drinking water systems, hot water system and will give top priority to safety, health water supply system, with safe, reliable, environmental health, economic application. Engineering practice at home and abroad has been proven to be one of the best overall performance of water supply system, a new, energy-saving and environment-friendly pipe water supply pipe is also a very competitive, improve water quality, improve people’s living standard will play no comparable to the role.
