1. When the displacement of the pipeline is greater than or equal to the maximum compensation of the joint, the number of joints should be increased to parallel displacement. Rubber Expansion joint is strictly forbidden to adjust the deviation of the pipeline so that the joint is in the limit of deflection displacement and deviation, and it is not allowed to exceed the limit ( Telescopic, displacement, deflection, etc.
2.High-level water supply or suspended water supply, the pipeline should be fixed on the hanger, bracket or anchor frame, and the joint can not bear the weight and axial force of the pipe, otherwise the joint should be equipped with anti-pull device (the bearing capacity must be greater than the pipe Axial force).
