Unidirectional hinge corrugated compensator（The BHJ type is composed of a connecting pipe, a corrugated pipe, and a pair of hinges connected to the connecting pipe. It can only absorb angular displacement of a single plane. When absorbing displacement, two or three angular expansion joints should be used in combination. The hinge of the expansion joint has the ability to withstand internal pressure thrust.
