Stainless steel pipe connections_Steel Pipe knowledge_News

Stainless steel pipes to connect a variety of ways, commonly used type of pipe fittings compression type, compression, push-in, welding and various derived connection, many of them are manufacturers of self-developed patented products. These connections have their own characteristics and application of occasions, but without exception, can ensure a solid, reliable, and no leakage.
1, compression type: piping inserted pipe fittings at both ends protruding U-shaped slot, built-in seals, special fittings tool socket parts entrapment to connect. The scope of application: DN (nominal diameter) ≤ 100mm, can be surface mounted Concealed.
2, compression: piping nozzle insert fittings from the fastening nut, compression force of the spiral tube of the mouth of the casing through the ring seal, complete piping connections. Scope of application: DN ≤ 150mm, can be surface mounted Concealed.
3, the annular argon arc welded (socket or butt welding): usually socket-type fittings and supporting from the closed, complete the supporting connection. Scope: public buildings and large building of the pipeline, the DN of 15 mm-100mm, the DN greater than 100 mm conventional butt welding; indoor surface mounted Concealed outdoor can be buried.
4 quick connect Flange Type: flange and the supporting ring argon arc between the flange gasket compression with a fast clip, from the confined role to complete the supporting connection . The scope of DN 15 mm-100 mm, public buildings and large buildings of the pipeline.
5, taper thread: external thread set with the matching ring argon arc internally ribbed tube connected to cone pattern from the closed, complete the supporting connection. The scope of DN 65 mm - 100 mm, public buildings and large F, the pipe can be used for ground subsidence, high temperature and pressure and other harsh environments.
6, the limit compression: piping weld ring flange or port, the connection to live then or semi-loose joint connections, rubber seals to limit seal compression 20% -30 %, into the metal seal groove to limit sealing to protect the sealing elements. The connector can use copper or carbon steel. The scope of DN 400 mm or less, apply to ground subsidence, all kinds of high temperature and pressure in harsh environments.
7, live-fit quick connect flange: the traditional flange into a loose joint flange, piping port flange or solder ring, collar embedded slot, slot set seal rubber limit compression method to protect the sealing elements. The scope of DN 400 mm or less can be used as the buried pipe.
8, heat shrinkable tubes: pipe connection can be on-site welding. Due to the construction site can not handle the welding point, the heat shrinkable tube for supplementary seal at the welding point, put a rubber welding sets, and then coat with a layer of special cross-linked polyethylene, the role of the thermal contraction, thereby reach a collapsible sealing. The scope of the pipes of DN 400 mm or less.
