Welded stainless steel pipe system

Welded connection definition:

Socket argon arc welding connection:
● The steel pipe is inserted into the socket of the pipe fitting and welded by tungsten argon arc welding (TIG).
butt argon arc welding connection:
● The steel pipe and pipe butt or steel pipe butt, with tungsten argon arc welding (TIG) fusion welding into an integrated connection.
● The wall thickness of socket welded pipe is 0.6~1.5mm, and pipe fittings with wall thickness greater than 1.5mm are suitable for butt welding.

welding type connection principle:

Principle: Insert the water pipe into the pipe fitting, and seal the pipe fitting and the pipe with circular argon arc welding to complete the connection.

Significant characteristics of welded connections:
