Double-flange Power Delivery Joint
Double flange power delivery joints are mainly connected with pumps, valves and other accessories. The flanges at both ends are connected to the pipeline respectively. The main function is to reduce the pressure thrust of the connected parts and compensate the pipeline installation error, but cannot absorb the axial displacement.
