PTFE lined expansion joint
PTFE lined expansion joint
The Product Structure Features
This expansion joint is used to eliminate stretching caused by climate change or the thermal expansion, displacement caused by other reasons in the pipe,container and equipment,which as a cushioning device. It can be installed on both ends in the pump of exit and entrance or other high-frequency mechanical, to reduce or eliminate the vibration and improve the life of the pipeline and sealing performance. To solve the problem which the metal compensator can’t do, reduce the enterprise costs, improve production efficiency. In addition, it can also be used to absorb the deviation design and the actual installation. Works reliably, compact structure, strong compensate ability,a variety of media corrosion resistant and long life.
