JWJ Universal Hinged Metal Compensator

Overview

Universal hinge compensator mainly compensate bending pipeline synthesis displacement by the way of angular deflection.

Introduce

It is fabricated item to be fitted into a pipeline to absorb movements in and forces exerted on the pipeline. A sheet of metal rolled into a cylinder and seam welded using the GTAW(TIG) welding process. Convolution(corrugations) are formed into the wall of the elements. The elements may be single ply or multi-ply.  

The joint consist of a metal expansion joint element with flanges or pipe weld ends fitted to facilitate the bolting or welding of the joint into a pipeline. Control devices commonly called hardware in the industry, can be attached to control the direction and amounts of movement that the bellows achieves.

Features

In situations where only angular movement is to be allowed, hinged and gimbaled expansion joints are the solution. Hinged joints are designed to take up angular motion in a single plane. Slotted hinge expansion joints permit axial movement through use of a slot, and require main anchors. Gimbal bellows will allow angular motion in all planes. Hinged and gimbaled joints are commonly used in combination to absorb various movements.
