Product Description
The sleeve compensator, called tubular expansion joint, is a compensation device for thermal fluid pipelines. It is mainly used for the absorption and compensation of axial thermal expansion displacement after the auxiliary installation of linear pipelines. It is a compensator directly installed in any pipeline conveying non corrosive unidirectional or multi-directional fluids. Sleeve type compensator It is widely used in the transmission pipeline of urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries. It is mainly composed of sleeve (core tube), shell, sealing material, etc. The sleeve compensator, called tubular expansion joint, is a compensation device for thermal fluid pipelines.

It is mainly composed of sleeve (core tube), shell, sealing material, etc. It is used to compensate the axial expansion of the pipe and axial rotation at any angle With small volume and large compensation, it is suitable for hot water, steam, grease and other media. The sliding sleeve can compensate for thermal expansion by sliding the outer sleeve. The inner sleeve of the sleeve type compensator is connected with the pipeline. It adopts the principle and structure of high-performance self pressure dynamic seal. It can slide freely in the shell with the expansion and contraction of the pipeline, and can meet the sealing requirements of any pipeline The shell and inner sleeve are sealed with a new type of synthetic material, which can withstand high temperature, corrosion and aging. The applicable temperature is - 40 to 150, and can reach 350 under special circumstances. It can not only ensure axial sliding, but also ensure that the medium in the pipe does not leak The sleeve type compensator is designed with an anti pulling device, which can ensure that it will not be pulled out when it expands to the limit position, thus greatly improving the safety of the whole pipe network. Sleeve type compensator is applicable to medium engineering pressure ≤ 2.5MPa and medium temperature - 40 ºC~600 ºC. The sleeve type compensator adopts a new sealing material, flexible graphite ring, which has the characteristics of high strength, small friction coefficient (0.04~0.10), no aging, good effect, convenient maintenance, etc.Data Reference
