Installation knowledge of aging resistant and high air tight rubber damping expansion joint
During the installation of aging resistant and high air tight rubber damping expansion joint, the screw rod of the bolt shall extend to the outside of the joint, and the bolt on each flange end face shall be repeatedly and evenly tightened according to the method of diagonal pressure to prevent pressure deviation. Screw joint should be tightened evenly with standard spanner. Do not use force applying stem to make movable joint slip, slide edge and fracture. Moreover, regular inspection should be carried out to avoid looseness causing disc detachment or water seepage. The aging resistant and high air tight rubber damping expansion joint shall be re pressurized and tightened before it is put into operation after initial pressure (such as installation and pressure test) or before it is put into operation again after long-term shutdown.

Precautions for use and storage:

High temperature, ozone oil and acid-base environment should be avoided when using or storing aging resistant and high air tight rubber damping expansion joints. Sunshade frame shall be built for outdoor or sunny and windward pipes. It is strictly prohibited to have any storm, rain or wind turbidity. It is forbidden to brush paint and wrap thermal insulation material on the surface of joint. Due to aging of rubber products, timely inspection and replacement should be carried out.
