Details:

Hydraulic pipe joint is used for the connection between pipes. Krh and krj series forging clamp flexible pipe joint is the patented product of our factory. It 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. It is resistant to high pressure, easy to install, and the comprehensive cost performance is much better than flange connection.

1. The theoretical mass includes the mass of clamps, terminations, sealing rubber rings, bolts and nuts.

2. The clamp with nominal diameter of 150 - 700 is composed of two lobes, and the clamp with nominal diameter greater than 700 is composed of four lobes.

3. Special requirements can be designed and manufactured separately.
