Axial outward pressure ripple compensatorMainly used to absorb axial displacement of pipelines,compensatorWhen under pressure, the corrugated pipe is subjected to tension (compression). The axial outward pressure corrugated compensator has the advantages of large compensation, good insulation performance, good stability, and the ability to eliminate residual media. Suitable for various laying forms such as pipeline installation, underground and non trench laying, etc; However, due to the larger effective area starting from the same nominal diameter compared to other corresponding axial corrugated compensators, the internal pressure thrust on the pipeline is greater, and the fixed bracket must be firm and reliable; Install the pipe section of the axial compensator,At the blind end of the pipeline,pipe bend,Variable cross-section,Parts and side branch pipelines equipped with shut-off valves or pressure reducing valves enter the inlet of the main pipeline,We need to set up a main fixed pipe rack.The main fixed pipe frame should consider the effects of corrugated pipe static pressure thrust and deformation elastic force.Between the two fixed pipe supports of the pipe section,Only one axial compensator can be set up.
1、 Technical parameters of axial outward pressure ripple compensator:
Product axial compensation amount:18mm-400mm
Indicating: The nominal diameter is500mmThe work pressure is0.6MPa(6kg/cm2)The wavenumber is8A stainless steel tube connected axial external pressure corrugated compensator.
Note: The setting of the drain port shall be in accordance with user requirements
2、 Precautions for installation of axial external pressure corrugated compensator:
1Before installation, the corrugated compensator should be checked for its model, specifications, and pipeline configuration, and must meet the design requirements.
2All moving components of the corrugated compensator shall not be jammed or restricted by external components, and the normal operation of each moving part shall be ensured.
3Compensators that require "cold tightening" should have auxiliary components used for pre deformation removed only after the pipeline installation is completed.
4The insulation material in contact with the corrugated pipe of the bellows compensator should not contain chlorine.
5During the hydrostatic test, the secondary fixed pipe bracket at the end of the pipeline equipped with a corrugated compensator should be reinforced to prevent the pipeline from moving or rotating. Attention should be paid to whether temporary supports need to be added during water filling for compensators and their connecting pipelines used for gas media. Cleaning solution for water pressure test96The chloride ion content does not exceed25PPM.
6For compensators with inner sleeves, attention should be paid to aligning the direction of the inner sleeve with the flow direction of the medium. The hinge rotation plane of the hinge type compensator should be consistent with the displacement rotation plane.
7After the installation of the piping system is completed, the yellow auxiliary positioning components and fasteners 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 ability under environmental conditions.
8After the hydrostatic test is completed, the accumulated water in the wave shell should be drained as soon as possible, and the inner surface of the wave shell should be quickly dried.
9It is strictly prohibited to use the deformation method of corrugated compensators to adjust the installation deviation of pipelines, in order to avoid affecting the normal function of compensators, reducing their service life, and increasing the load on pipeline systems, equipment, and supporting components.
10During the installation process, welding slag is not allowed to splash onto the surface of the wave shell, and other mechanical damage to the wave shell is not allowed.
