Precautions for the installation and use of the bent pipe pressure balance corrugated compensator

 

●Curved pipe pressure balanced corrugated compensator (expansion joint) is generally applied to straight pipelines overhead and installed horizontally.

●All small ties must be removed after the installation of curved pipe pressure balanced corrugated compensator (expansion joint).

●In order to reduce the elastic reaction force of the bellows expansion joint on the support, it should be communicated with the manufacturer before installation to pre-pull or pre-pressure of such bellows expansion joint (which can be achieved by adjusting the small ties on it).

●Pay attention to protect thin-walled parts such as bellows from damage such as impact, scratch, arcing, and welding splash during installation.

●If there is a flow direction mark, the media flow direction should be consistent with the media flow direction during installation.

●Before the guide bracket and fixed bracket are properly installed, they should be installed in strict accordance with the piping system design drawings.7. No pressure test should be performed until all guide brackets and fixed brackets are properly installed. If a sectional pressure test is performed on the entire piping system, confirmation of the corrugated compensator manufacturer is required.
