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.
