Single Hinged expansion joint with welding ends nice quality OEM accepted

Product description

Single hinge type corrugated compensator is also called expansion joint and expansion joint, which is composed of the bellows (a kind of elastic element) that make up its working body and accessories such as end pipe, bracket, flange and conduit.

Details

Purpose:

single hinge type ripple compensator is suitable for compensating connection of angular displacement:

1. Flange connection

2. Angular compensation of connecting products: ± 4 degrees-± 9 degrees

Installation and use requirements

1, single hinge type ripple compensator before installation should first check its model, specifications and pipe configuration, must meet the design requirements.

2. For compensator with inner sleeve, attention should be paid to make the direction of inner sleeve barrel consistent with the direction of medium flow, and the hinge rotational plane of hinge compensator should be consistent with the displacement rotational plane.

3. For the compensator that needs to be "cold tight", the auxiliary components used for pre-deformation shall be removed after the installation of the pipeline.

4. It is strictly prohibited to use the method of deformation of ripple compensator to adjust the installation error of pipeline, so as not to affect the normal function of compensator, reduce the service life and increase the load of piping, equipment and supporting members.

5. During installation, welding slag is not allowed to splash onto the surface of the wave shell, and other mechanical damage is not allowed to the wave shell.

6. After the installation of piping, the yellow auxiliary positioning member and fastener used for installation and transportation on the corrugated compensator should be removed as soon as possible, and the limit device should be adjusted to the specified position according to the design requirements, so that the piping system has sufficient compensation capacity under environmental conditions.

7. All moving components of the compensator shall not be jammed by external components or their range of motion shall be limited, and the normal operation of each moving part shall be guaranteed.8. During the hydraulic test, the secondary fixed pipe rack with compensator pipe end should be reinforced so that the pipe does not move or rotate.For the compensator for gas medium and its connecting pipeline, it is necessary to pay attention to whether additional temporary support is needed when filling water.The content of 96 chlorine ions in the cleaning solution for hydrostatic test shall not exceed 25PPM.

9. After the hydrostatic test, the water in the wave shell should be drained as soon as possible, and the inner surface of the wave shell should be blown dry.

10. The insulation material in contact with the bellows of the compensator shall be free from chlorine.
