Application: It is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, water heating, fire protection, electric power and other basic projects. According to different materials can be made into acid, alkali, corrosion, oil, high temperature, radiation, wear resistance, aging and other varieties, to adapt to a variety of media and environment.

Expansion Joints Feature

1. Small volume, light in weight, very good flexibility, convenience installation and maintenance.

2. Transverse displacement, axial displacement, angular displacement.

3. Reduce noise, shock absorption.

Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:

1) Absorb movement

2) Improved thermal stability

3) Relieve system strain due to thermal change, load stress, pumping surges, wear or settling

4) Reduce mechanical noise

5) Compensate for misalignment

6) Eliminate electrolysis between dissimilar metals
