Buried corrugated compensators are used for the axial compensation of buried pipelines.With bending capacity,this type of compensator does not conside the influence of sinking,characterized by large compensation and the long service life.
Unconstrained type compensator named based on the elimination of general compensation for the more constraints, can effectively resist pipeline lateral displacement and angular displacement, and both contribute to the stability of selfguided ability, but also has to overcome installation error, the small size and large.
