How to install double flange steel limit expansion joint

When using pipeline expansion joint in hardware pipeline, it mainly provides great convenience for expansion caused by temperature difference of long distance pipeline. Due to its comprehensive performance, it is commonly used in pipeline systems such as valves, fire fighting and chemical industry. Pipeline expansion joint installation method. 1. The type, specification and pipeline configuration of the expansion joint should be checked before installation.
2. For the expansion joint with inner sleeve, attention should be paid to make the direction of the inner sleeve consistent with the direction of media flow, and the hinge rotation plane of the hinge expansion joint should be consistent with the displacement rotation plane.
3. Cold tightening of the compensator is required, and the pre-deformed auxiliary members can be removed only after the pipeline is installed.
 
Pipeline expansion joint is a new product for pump, valve, pipeline and other equipment connection deployment and pipeline connection. They are connected into one whole by the whole bolt with certain displacement for testing according to the installation size on site during installation and maintenance. Axial thrust can go to the whole piping system. This not only improves efficiency, but also protects the connection of piping equipment such as pumps and valves. Expansion joints are a large category of pipeline installation, whose function is to compensate and absorb the expansion and contraction deformation caused by pipeline heating and reduce the impact of equipment vibration on the pipeline, i.e. compensate and absorb the axial, lateral and angular thermal deformation of the pipeline. Expansion energy saving to prevent leakage or damage due to excessive displacement of the compensation joint, used to absorb axial displacement and bear pressure thrust within the allowable displacement range of the pipeline loose-fitting connection. Flexible interface generally refers to non-metallic fiber fabric compensator or rubber joints, or stainless steel flexible connections.
