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.

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.
