Flange type sleeve compensatorIt is a compensation device for thermal fluid pipelines, mainly used as an auxiliary device for straight pipelines. Suitable for hot water, steam, and grease media, it compensates for thermal expansion by sliding the outer sleeve through sliding motion.

1、 Flanged sleevecompensatorProduct Features

The service life of flange sleeve compensator is long, and its fatigue life is equivalent to that of pipelines. The sliding surface has undergone special treatment and has good corrosion resistance in environments such as salt water and salt solutions, which is higher than that of austenitic stainless steel50More than double. At the same time, if the sealing effect weakens due to wear and tear after many years, the flange can be tightened again to enhance the sealing performance. Alternatively, the bolt can be loosened, the pressure ring can be removed, and one or two layers of sealing rings can be installed to tighten the pressure ring and continue to be used.

2、 Applicable conditions for flange sleeve compensator

Suitable for medium engineering pressure ≤2.5MPa,medium temperature-40℃~600℃.

3、 Installation and usage requirements for flange sleeve compensator

1The compensator should be checked for its model, specifications, and pipeline configuration before installation, and must meet the design requirements.

2For 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.

3Compensators that require "cold tightening" should have auxiliary components used for pre deformation removed only after the pipeline installation is completed.

4After 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.

5All active components of the compensator shall not be jammed or restricted by external components, and the normal operation of each active part shall be ensured.

6During the hydrostatic test, the secondary fixed pipe bracket at the end of the pipeline equipped with a 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.

7It 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.

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.

9The insulation material in contact with the compensator bellows should not contain chlorine.

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.
