Rubber Expansion joints, as shock-absorbing and noise reducing products for pump valve pipeline connections, have special materials that have the effect of shock-absorbing and noise reduction. When using steel pipes, attention should be paid to correct installation and regular inspection and maintenance of rubber joints.
When inspecting Rubber Expansion Joints, the main focus is on the following aspects:
Check for any dripping at the product interface. If there is any dripping, continue to tighten the bolts or strengthen the interface sealing plate.
Whether the flange is intact and without cracks. If cracks are found on the flange, it needs to be replaced in a timely manner
Is the deformation of the sphere severe. If the rubber ball is severely stretched and deformed, a limiting device should be installed in a timely manner to ensure the normal use of the rubber joint.
Check the degree of colloid aging, replace aged products in a timely manner, and avoid danger
As is well known, the connection method between Rubber Expansion Joints and pipelines or mechanical equipment is very important. If the connection method is improper, it will also damage the rubber joints of the pipeline, leading to operation, exhaust, dripping, and leakage. A wide range of rubber joint connection methods include flange plate connection, clamping connection, butt welding connection, pipe thread connection, sleeve joint connection, clamp joint connection, self sealing connection, and other docking methods. At present, let's explain in detail the flange plate connection: flange plate connection is a more commonly used rubber joint connection method, which is consistent with the flange on the pipeline. The mechanical equipment is fixed in the pipeline with anchor bolts.
