SSQ type cast iron retractor Installation precautions:
1. The retractor should first check its model, specifications and pipe configuration before installation, and must meet the design requirements.
2. For the retractor with the inner sleeve, the direction of the inner sleeve should be consistent with the flow direction of the medium. The hinge rotation plane of the hinge type retractor should be consistent with the displacement rotation plane.
3. A “cold tight” retractor is required. The auxiliary components used for pre-deformation should be removed after the pipeline is installed.
4. It is strictly forbidden to use the method of deformation of the retractor to adjust the installation of the pipeline to avoid the normal function of the retractor, reduce the service life and increase the load of the piping, equipment and supporting members.
5. During the installation process, the welding slag is not allowed to splash onto the surface of the wave shell, and the wave shell is not allowed to be damaged by other machinery.
6. After the pipe system is installed, the yellow auxiliary positioning members and fasteners used for installation and transportation on the wave expansion device 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 pipe system has under the environmental conditions. Full compensation capacity.
7. All moving parts of the retractor shall not be stuck or restricted by the external components, and the normal movement of each active part shall be guaranteed.
8. During the hydrostatic test, the secondary fixed pipe rack equipped with the end of the retractor pipe should be reinforced so that the pipe does not move or rotate. For the retractor used for the gas medium and its connecting pipeline, it is necessary to pay attention to whether it is necessary to add a temporary bracket when filling the water. The 96-chloride ion content of the water test water cleaning solution does not exceed 25 PPM.
Use range:
Because the retractor has good comprehensive performance, it is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power and other basic projects.
