JJL Hinged Metal Expansion Joint

Overview

Hinged Pipe Expansion Joints contain hinges or pivots which allow the unit to bend in a single plane. These units are designed to restrict axial deflection, either in extension or compression. The hinge mechanism is typically designed to accept full pressure thrust. Also, because of the hinge mechanism’s design, shear loads, such as from the weight of adjacent piping, can be accepted by this pipe expansion joint, relieving the piping designer of having to provide additional supports and anchors required by the Single type.

Hinge corrugated compensator also called expansion joint, slip joint, composed by bellows, tube, bracket, flange and catheter. 

Introduction:

Features

These expansion joints incorporate hinged or gimbal mechanisms to accommodate angular movement while preventing axial displacement.

Best for: Controlled directional movement in pipelines

Materials: Stainless steel, alloy steel

Common Uses: Power generation, pipeline stress relief, heat exchangers

Key Feature: Allows controlled motion while limiting excessive stress
