The sleeve compensator is called a tube expansion joint. It is a compensation device for hot fluid pipelines. It is mainly used to absorb and compensate the axial thermal expansion displacement that occurs after the auxiliary installation of the linear pipeline. It is a kind of direct installation in any non-corrosive one-way or multiple Compensator in the pipeline to the fluid. Sleeve-type compensator. It is widely used in transportation pipelines in urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries. It is mainly composed of sleeve (core tube), shell, sealing material, etc.

The inner and outer surfaces of the elbow should be smooth, without detrimental strength and appearance defects, such as scars, scratches, heavy leather, etc., after the defects are found, they should be ground and the thickness of the ground should not be less than 93.5% of the original wall thickness. The ground should be smooth and the defects should be cleared with colorant or magnetic particle inspection.
