Ayvaz metal bellowed expansion joints are designed and built using the latest CAD and production techniques. The main usage areas of expansion joints are the pipeline applications. Our expansion joints are constantly used to meet such needs of industry.

Axial expansion joints are designed to absorb movements aligned with the pipeline axis. They are fitted in the pipeline, in line with the movement. They require an anchor each end of the system to resist the pressure force and to compress the bellows. Proper pipe alignment guides are required.

AXIAL COMPRESSION

The dimensional shortening of an Expansion Joint along its longitudinal axis. Axial compression has been referred to as axial movement, traverse or compression.

AXIAL EXTENSION

The dimensional lengthening of an Expansion Joint along its longitudinal axis. Axial extension has been referred to as axial movement, traverse, elongation or extension.
