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

Features

1. Metal expansion joints are used in a wide variety of piping application to compensate for thermal expansion or contraction and to absorb equipment vibration or pipe motions.

2. We manufacture single, two-ply and multiply testable bellows in different sizes using precision forming technology.

3. The bellow is made of stainless steel, whcih have good performance for extreme pressure, temperature and corrosive conditions.

4. Compensate axial movements.

5. Optimized design for fatigue resistnce and endurance.

6. Widely used to absorb termal expansion in pipe systems carring water, steam, oil and gases.

7.Stainless bellows compensators or expansion joints are designed according to the client's specifications ad design conditions.
