Introduction of stainless steel expansion joint
Rubber joints, also called the soft rubber tube joints, flexible rubber joints, rubber flexible joints can be curved around the rubber joints, high-pressure rubber joints, rubber shock absorbers, such as compensation. Press the connection points loose flanges, fixed flanges and threaded three kinds; according to the structure can be divided into five kinds of single ball, double ball, reducers body, bending the ball and pressure plate pipe. The inner and outer layers of plastic, ply and bead composition tubular rubber member vulcanized after forming and metal flanges or parallel connector loose jacket combination. This product can reduce vibration and noise, and thermal expansion and contraction due to temperature changes from the compensation due to the widely used in various piping systems.

Rubber joint Installation instructions
1, soft rubber joints when installing non-super-displacement limit installation.
2, flat, vacant, vertical installation rubber joints, axial displacement of the actual work pressure rubber joints supporting force smaller than the pipe, otherwise it should install anti-pull-off device to prevent pressure on the work to pull off.
3, the pipe must have a fixed support or mounting bracket, mounting bracket force must be greater than the axial force. Vertical mounting and overhead installation of both ends need to install the appropriate mounting bracket and force stand to prevent the pressure on the work to pull off.
4, the mounting bolts should be symmetrical pressure gradually tightened to prevent partial disclosure.
5, should be installed away from heat, prohibited the use of this product does not meet the requirements of the media.
