① high demand building water supply pipes

According to the construction industry “95” project and vision 2010 target platform for measuring, 2001-2010 years, the annual demand of 50~60 million km of pipes, hot and cold water pipes in residential buildings demand of 400,000 km. The view was expressed that the development of stainless steel pipes, to improve the quality of modern architecture, and of great significance.

② pipeline direct drinking water rapidly
With the development of the national economy, direct drinking water system in Beijing, Shenzhen, Shanghai, Chongqing and other cities have developed rapidly, economically developed secondary cities is also actively planning to catch up. In drinking water, stainless steel piping systems are second to none. Current grade hotels and public places have been configured or configured in direct drinking water pipeline.
③ domestic alternative to imported future
In order to promote the stainless steel pipe, from China in the 1990 of the 20th century from reduced wall thickness, reduced costs, and address “the wall of height to diameter ratio high precision” problem of thin-walled stainless steel tube, stainless steel tube is widely used, is developing very quickly. A pipeline must be able to promote, not domestically. , And has been part of the factory with the production and further development of capacity of thin-wall stainless steel pipe and fittings.
Connection mode

Stainless steel pipe connection method, common types of pipe fittings are compression, compaction, the Union type, push push-type, threaded, socket weld, flanged connections, welding and welding and traditional connections combined with the derived series connection. These connections, different according to its principles, its scope is slightly different, but they are easy to install, strong and reliable. Connection with sealing ring or gasket material, choose in line with national standards of silicone rubber, nitrile rubber and EPDM rubber, and remove the user’s worries.
Compression connections step

1, broken pipes: according to required length cut tubing, broken pipe, do not force too much to prevent pipe round loss.
2, deburring: pipe cut off, clean burrs should be removed, so as not to cut sealing ring.
3, line: to make the pipe fully inserted into the fitting socket, you must draw a line in the pipe end to mark the insertion length.
4, Assembly: seals should be correctly installed in the pipe within the u-shaped Groove, insert the tube tube socket, waiting for the press.
5, crimping: when crimping, pipe protruding parts on the mold concave grooves, NIP and perpendicular to the pipe axis.
6, check: when crimping is complete, use a special gauge to check the crimping dimensions.
