Pipe Expansion Joint for pressure and vacuum| Flexpert Bellows Pvt Lt

Expansion Joint

Pipe Expansion Joint is isolated in the vacuum pump from another system to allow the thermal expansion and misalignment in the piping system.  The Rubber expansion joint features a single or double-arched bellow constructed for the molded elastomeric.

The function of Expansion Joints

·         Reduce pressure thrust and load

·         Reduce sound transmitted in the pipeline system

·         Directional movement

·         Compensate misalignment

They typically come in three different applications:

·         Metal

·         Rubber

·         Braided

Metal:

 Metal Expansion Joints are compensating elements of thermal and relative movements in the pipelines and compensator.   It consists of more than one metal bellows connector at both ends.

Rubber:

 Rubber Bellows are used in Pumps and pipelines. Bellows eliminate the stress and pressure in the metallic pipeline and compensate axial and lateral misalignment. The Vibration stops the hammering effect in the piping system.

 

Braided:

Braided stainless hoses are with metal liners aren’t technical expansion joints, more of the flexible connector.  They work in high pressure and temperature application requiring vibration damping or misalignment.   The Braids provide lateral and angular movement.
