Specification for installation of stainless steel corrugated compensator

Time: 03-26 󰃯 Reading times: 235 󰃳 Editor in charge: The sea 󰃗 Column: product focus

Introduction: 1. The model, specification and pipeline configuration of stainless steel corrugated compensator should be checked before installation to meet the design requirements. 2. For the compensator with inner sleeve, pay attention to make the direction of inner sleeve cylinder consistent with the direction of medium flow, and the hinge of hinge type compensator rotates

1. Stainless steel ripple Compensator The specification and configuration of the pipe should be checked before installation.
2. For the compensator with inner sleeve, attention should be paid to make the direction of inner sleeve cylinder consistent with the direction of medium flow, and the hinge rotation plane of hinge type compensator should be consistent with the displacement rotation plane.
3. For the compensator that needs to be "cold tight", the auxiliary components used for pre deformation should be removed after the pipeline installation.
4. It is forbidden to use stainless steel Corrugated compensator In order to avoid affecting the normal function of the compensator, reducing the service life and increasing the load of piping, equipment and supporting components, the method of deformation is used to adjust the installation out of tolerance.
5. During the installation, welding slag is not allowed to splash on the surface of the wave shell, and the wave shell is not allowed to be damaged by other pipelines.
6. After the piping system is installed, the Yellow auxiliary positioning components and fasteners used for installation and transportation on the bellows compensator shall be removed as soon as possible, and the limiting device shall be adjusted to the specified position according to the design requirements, so that the pipeline system has sufficient compensation capacity under environmental conditions.
7. All moving elements of stainless steel corrugated compensator shall not be blocked by external components or limit its range of motion, and the normal operation of each moving part shall be ensured.
8. During the water pressure test, the secondary fixed pipe support with compensator pipe end shall be reinforced to prevent the pipeline from moving or rotating. For the compensator used in gas medium and its connecting pipeline, it is necessary to add temporary support when filling water. The content of 96 chloride ion in the cleaning solution for water pressure test shall not exceed 25ppm.
The test of water pressure in the shell should be finished as soon as possible.
10. The insulation material in contact with the compensator bellows shall be chlorine free.
Setting distance of stainless steel corrugated compensator: the hot water supply pipeline should make full use of natural bending to compensate for thermal expansion and contraction. If the straight-line section is too long, the compensator should be set. The type, specification and position of the compensator shall meet the design requirements and be pre stretched according to relevant regulations.
