  • Product Description
  • Detailed parameters
  • Single flange loose sleeve limit expansion device This series of pipeline compensators can be widely used in petroleum, chemical, food and medicine, textile, papermaking, hydropower, ships, water supply and drainage systems for all corrosive and non-corrosive gases, liquids, The connection of semi-fluid and solid particle powdery medium pipelines.

    Single flange loose sleeve limit expansion device is a new product connected with pumps, valves, pipelines and other equipment and pipelines. They are connected by full bolts to make them become a whole and have a certain displacement, which is convenient for installation. Can withstand the axial pressure of the pipeline. In this way, it can be adjusted according to the on-site installation size during installation and maintenance. At work, it not only improves work efficiency, but also protects pipeline equipment such as pumps and valves.

    Limit expansion device is also called expansion joint, expansion joint, compensator. The single flange loose sleeve limit expansion and contraction can be axially expanded and contracted within a certain range, and can also overcome the offset caused by different axial directions of pipeline docking within a certain angle, which can greatly facilitate the installation and disassembly of valve pipelines. It can be freely expanded and contracted in the allowable expansion and contraction of pipelines. Once it exceeds its maximum expansion and contraction, it acts as a limit to ensure the safe operation of pipelines.

    Advantages: convenient installation, reliable sealing, convenient maintenance.

    Features: the realization of the pipeline side flange connection, one side for the welding of the inconsistency of the convenient connection.
