Elbow Pressure Balanced Expansion Joints
Features
The expansion joint comprises of pipe tee, blind plate, rod and three bellows with the same diameter. Two working bellows are mounted to the front end of medium output to absorb lateral offset of pipelines; the blind plate has one balancing bellow to absorb axial displacement of pipelines; and the rod is to withstand pressure thrust. It is applicable to L type, Z-type, and 3D Z-type pipelines, in particular, turbines, compressors, pumps, and tank exits. It is to reduce the pressure thrust and damage forces to the above-mentioned equipment.
