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.

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

Introduction

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

Design temperature: -20~+400℃


Installation notes

1. Check model, specification and pipe configuration before installation, must conform with design requirement.

2. Sleeve direction and medium flow direction have the same direction, hinge compensator rotate surface should be consistence with displacement rotation surface.

3. Compensator that need cold tighten, pre-deformation auxiliary components can be removed after pipeline installation finished.

4. It is strictly prohibited to use bellow compensator deformation to adjust pipeline installation inaccuracy, so as not to affect the normal function of compensator, shorten service life and increase pipe, equipment and bearing component load.

5. During installation, it is not allow welding slag splash to the wave shell surface, not allow wave shell surface damaged by other machine.

6. After pipe installation, demounting the fastening component and yellow assisted positioning component that used for conveying in bellow compensator, adjust the limited device to the specified place, make the pipe have full compensation ability in different environment condition.

7. All components of compensator should be in the condition of moving to ensure all components normal operation.
