Connection method of 316L stainless steel pipe

1. Welding type (socket type or butt type welding):

circular argon arc welding is performed on the usual socket type stainless steel pipe and supporting pipe fittings, which acts as a seal and completes the supporting connection. Scope of application: Public buildings and large-scale building pipes, DN is 15mm-100mm, and DN is more than 100mm, most of which are conventional butt welding; indoors can be exposed and concealed, and outdoors can be buried.

2. Quick-connect flange type:

Carry out annular argon arc welding on the flange and the stainless steel pipe, and use the quick clamp to compress the gasket between the flanges, which acts as a seal and completes the matching connection. The scope of application is DN 15 mm-100 mm, public buildings and large building pipelines.

3. Taper thread type:

The outer thread sleeve and the stainless steel pipe are welded by circular argon arc welding, and the inner thread pipe fittings are sealed by taper connection to complete the matching connection. The scope of application is DN 65 mm-100 mm, public buildings and large-scale building pipelines, which can be used in harsh environments such as foundation subsidence, high temperature and high pressure.

4. Limit compression type:

the piping adopts flanging or port welding ring, and the connection method of stainless steel pipe is union or semi union connection. After compressing the limit seal of the rubber sealing ring by 20%-30%, it enters the metal sealing groove. bit seal to protect the sealing element. Joints can be copper or carbon steel. The scope of application is DN below 400 mm, suitable for harsh environments such as foundation subsidence, various types of high temperature and high pressure.
