A single metal bellows element fitted with flanges or pipe weld ends, with external gimbal ring and offset hinge plates and pins to contain complex multi-plane movements in a piping system.

Suitable for angular movement in all planes controlled by the hinges on the gimbal rings.

Gimbal hardware is attached to contain pressure thrust forces, and in many cases could support the dead weight of the adjacent pipework. Heavy expensive main anchors are not necessary and only minimal guiding is required.

Manufactured to the guidelines laid down in the Standards of the Expansion Joint Manufacturers Association Inc. (EJMA).
