Description

The sheet metal expansion joint is also called a telescopic joint, an Sheet metal expansion joint, and a compensator. The telescopic expander can be axially extended and retracted within a certain range, and can also overcome the offset caused by the different sheet metal expansion joint of the pipe within a certain angle, which can greatly facilitate the installation and disassembly of the valve pipe, and allow the amount of expansion and contraction in the pipe. Sheet metal expansion joint can be freely stretched and stretched. Once it has passed its maximum expansion and contraction, it will play a limit role and ensure the safe operation of the pipeline
