Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plastic lined pipeline compensator, especially a plastic lined pipeline compensator convenient for butt joint adjustment. BACKGROUND

[0002] Pipeline compensator is also called expander or expansion joint, and is mainly used for compensating thermal expansion and cold shrinkage of pipeline caused by temperature change. If the pipeline cannot expand or shrink freely when the temperature changes, thermal stress will be generated in the pipeline. Therefore, such stress must be considered in pipeline design. Otherwise, it may cause pipeline rupture and affect normal production. As an important part of pipeline engineering, compensator plays an important role in ensuring long-term normal operation of pipeline.

[0003] However, the existing compensator needs to be fixed and installed on both ends of the corrugated pipe first during installation, and then fixedly connected with the pipeline through the flange plate. This connection method is time-consuming and laborious. Therefore, we propose a plastic lined pipeline compensator convenient for butt joint adjustment to solve the above problems.
