Ring Type Pipe Joint

Ring Type Pipe Joint

The ring type pipe joint is used for the connection between pipes.

Tubing coupling mainly aims to solve the existing couplings easily generated due to fatigue fracture stress concentration problems.

Krh and krj series forging clamp type flexible pipe joints can effectively compensate the thermal expansion and cold contraction of the pipeline system due to temperature change, and compensate the angle change caused by the sinking of the pipeline foundation. They are resistant to high pressure, easy to install, and the comprehensive cost performance is much better than that of flange connection.
