The quotations of expansion joints are communicated upon request, as the creations are as varied as the requirements of use.

Axial expansion joints, formed by one or more bellows, are designed and built to absorb axial movements. They are always installed between two fixed points sized so that they can withstand the thrust due to internal pressure.

The bellows is the fundamental part of the expansion joint and is obtained by means of a hydraulic or mechanical process from stainless steel or alloy steel sheet having a longitudinal weld. The choice of material is made based on the requirements: resistance to fatigue, resistance to corrosion, weldability. A series of parallel metal waves are formed with a controlled process that ensure maximum flexibility and reliability.

The compensator terminals can be welded or flanged. They are normally made of carbon steel, but stainless steel can be used on request. The standard flanges are drilled according to UNI-ANSI standards.

The conveyor avoids direct contact between the bellows and the fluid. It is entirely welded to the compensator and reduces thermal stress, attenuates pressure drops, turbulence and erosion.

According to the type of expansion they can absorb, compensators are classified as:

Axial

Universal

Angular

Spherical angular

Lateral

Spherical lateral

Axial with eliminated thrust

Universal with eliminated thrust
