Metal Expansion Joints and Metal Bellows

Expansion Joints for Tank Farms

A complete range of Expansion Joints for Oil Terminals and Tank Farms

The tank and the adjacent piping are considered to move and therefore Expansion Joints should be installed at storage tank to pipelines connections to absorb tank settlement, misalignments and movements due to thermal expansion and contraction.

In most cases universal expansion joints are used for these applications as they are the ideal solution to accommodate deviations in the piping system and possible movements or settlement of the tank.
