How to Protect the PTFE Lining During Installation of PTFE Lined Bellows Expansion Joints?

Precautions for Protecting PTFE Linings During Installation of Ptfe Lined Bellows Expansion Joints:

1.Avoid Impacts and Scratches
During transportation and installation, exercise extreme caution to prevent impacts or scratches to the expansion joint. PTFE Lined Bellow Expansion Joint is typically fabricated by pressing thin-walled stainless steel plates, so avoid sparks generated during welding processes from contacting the unit to prevent damage.

 

2.Prevent Foreign Object Ingress
Before installation, thoroughly clean the bellows and pipeline interior to remove debris, ensuring unobstructed movement of the bellows.

 

3.Correct Installation Orientation
For expansion joints with directional flow requirements, install according to the flow direction arrow indicated on the unit.

 

4.Avoid Excessive Displacement
Do not adjust piping system alignment errors by deforming the expansion joint, as this may cause excessive displacement and damage.

 

5.Even Bolt Tightening
When securing the expansion joint, tighten bolts evenly to avoid uneven stress distribution on the unit.

 

1.Implement Protective Measures in Corrosive Environments
In installations involving corrosive media, consider adding protective layers or shielding devices to safeguard the PTFE lining.

By adhering to these measures, the Ptfe Expansion Joint can be effectively protected, ensuring optimal performance throughout its service life.
