  •  The selection of compensator should be in accordance with the structural configuration of the pipeline

    The selection of compensator should be in accordance with the structural configuration of the pipeline

    The development of compensators in China has a history of nearly half a century. Up to now, there are many kinds of compensators, which can be described as "Eight Immortals crossing the sea". For example, the axial corrugated compensator is mainly used to compensate the axial displacement of the pipeline. The hinged compensator can realize the angular displacement compensation when it is used alone, and can compensate the pipe when the two are used together The lateral displacement of the line.

  •  Many factors affecting the type of compensator

    Many factors affecting the type of compensator

    The angular displacement is the inclination of the pipe section realized by the angular displacement of the bellows itself. The pressure bearing area of the protruding side is larger than that of the concave side. Because of the unbalanced forces on both sides, the compensator will have an additional lateral force, so it is easier to produce instability than the axial compensator
