Genite Valve Industry produces flange sleeve compensators

The flange sleeve is called a tubular expansion joint or a pipe expansion joint. It is a compensation device for hot fluid pipelines and is mainly used for the auxiliary installation of linear pipelines. It is suitable for hot water, steam, and grease media. It achieves thermal expansion compensation through the sliding movement of the sliding sleeve against the outer sleeve. Features: The flange sleeve compensator has a long service life and its fatigue life is equivalent to that of pipelines. The sliding surface has been specially treated and has good corrosion resistance in salt water, salt solution and other environments, which is more than times higher than that of austenitic stainless steel. At the same time, when the sealing effect is weakened due to wear after many years, the flange can be tightened again to enhance the sealing performance. You can also loosen the bolts, remove the pressure ring, install one or two layers of sealing rings, and tighten the pressure ring. ,continue to use.
Applicable conditions apply to medium engineering pressure and medium temperature ℃~℃.
Installation conditions
Before installing the compensator, check its model, specifications and pipeline configuration, and it must meet the design requirements.
For compensators with inner sleeves, care should be taken to ensure that the direction of the inner sleeve is consistent with the direction of medium flow. The hinge rotation plane of hinge-type compensators should be consistent with the displacement rotation plane.
For compensators that need to be cold-tightened, the auxiliary components used for pre-deformation should be removed only after the pipeline is installed.
It is strictly forbidden to use the method of deforming the corrugated compensator to adjust the installation tolerance of the pipeline, so as not to affect the normal function of the compensator, reduce the service life and increase the load on the piping system, equipment and supporting components.
During the installation process, welding slag is not allowed to splash on the surface of the wave shell, and the wave shell is not allowed to suffer other mechanical damage.
After the piping system is installed, 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 to make the piping system in the environment There is sufficient compensation capability under the conditions.
All movable components of the compensator must not be blocked by external components or limit their range of movement, and the normal movement of each movable part should be ensured.
During the hydraulic test, the secondary fixed pipe frame at the end of the pipeline equipped with the compensator should be reinforced to prevent the pipeline from moving or rotating. For compensators used for gas media and their connecting pipelines, attention should be paid to whether temporary brackets need to be added when filling with water. The chloride ion content of the cleaning fluid used in the hydrostatic test shall not exceed.
After the hydraulic pressure test, the accumulated water in the wave shell should be drained as soon as possible, and the inner surface of the wave shell should be dried quickly.
The insulation material in contact with the compensator bellows should not contain chlorine.
