RF type High pressure rubber expansion joint

The main function of the single flange expansion joint is to withstand the pressure and thrust inside the pipeline. Compensation pipeline due to thermal expansion and cold shrinkage caused by the size change, namely compensation pipeline axial displacement. At the same time easy to connect the pump or valve installation, maintenance and disassembly. If the instantaneous pressure of the pipeline is too large or the displacement exceeds the expansion capacity of the expansion device itself, the expansion tube of the expansion device will be broken, resulting in damage to the related connected pumps, valves, and even the entire pipeline. The reason why expansion joints can operate in harsh environments is the material and special surface treatment.

Single flange expander is mainly used in the mechanical displacement and heating displacement of the pipeline system to absorb vibration and reduce noise. It can perform displacement absorption in all directions. When installing the expander, adjust the installation length of both ends of the product or the flange. Evenly tighten the gland nuts diagonally, and then adjust the limit nuts, so that the pipe can be freely expanded and contracted within the range of expansion and contraction. Lock the amount of expansion to ensure the operation of the pipeline.
