Introduction to the main connection methods of stainless steel pipe fittings. With the development of national economy and the improvement of people's living standards, thin-walled stainless steel water pipes and stainless steel pipe fittings have become a new trend in the development of domestic water supply pipeline systems.

What are the main connection methods of stainless steel pipe fittings?

The domestic thin-walled stainless steel water pipe is a new type of pipe that came out at the end of the 1990s. Due to its safety, health, high strength, good corrosion resistance, durability, long life, maintenance free, beautiful and other characteristics, the stainless steel water pipe has a strong development momentum and has been widely used in building water supply and direct drinking water pipes.

The "card convex connection method" belongs to an improved method of compression connection technology. The utility model is characterized in that: a special pipe expanding tool is used at the proper position of the thin-walled stainless steel pipe end, and the pipe is rolled from the inner wall to the outside (radially) to form a flange ring, and then the pipe is inserted into the pipe fitting with a socket cone bench shaped PTFE seal ring and a lock nut. When the lock nut is tightened, the flange ring pushes the compression cone bench shaped PTFE seal ring to play a sealing role. The design principle of stainless steel pipe fittings is basically the same as that of the previous galvanized pipe fittings, which greatly avoids the tedious processes in engineering design, budget and construction, and is more conducive to popularization and application.

Clamp type connection

A connection mode in which a bell fitting with a sealing ring is used to connect the pipe and a special tool is used to compress the pipe orifice for sealing and fastening.
