METALLIC EXPANSION JOINTS

Metallic expansion joints are an efficient solution as connection between pipe. We povide various designs adapted to your technical specifications allowing to safely absorb all dimensional changes of pipe systems and ducts. Metals are suitable for use at high temperatures up to 1200°C. 

Metallic bellows are submitted to construction codes EJMA, ASME, AD Merkblatter…

Good to know

Expansion joint design depend of your technical specifications, mediums and operating conditions of your installations. It is recommended to consult us to define the best solution for your needs.

METALLIC EXPANSION JOINT IT IS...

Metal expansion joints can withstand pressures of up to 450 bar(g).

Metal bellow compensate temperature variations imposed by heat-induced and contraction of your ducts up to 1200°C.

Metallic expansion joints installed can have different shapes : round, rectangular, octogonal, oval…
Depending of design, it absorbs lateral, angular, axial or combined movements. 

Metallic bellows ensure better sealing than other expansion joints.
