How to extend the service life of wear-resistant rubber joints
Abrasion-resistant rubber joints are made of nitrile rubber with excellent abrasion resistance, which is airtight and resistant to heat, ozone, aging, shock absorption and electrical insulation. It has good resistance to sunlight and ozone, and can be exposed to animal or vegetable oils or oxidizable chemicals.
Although it is resistant to sunlight, it should not be exposed to sunlight for a long time and should avoid high temperature, ozone oil and acidic and alkaline environment. Pipes used outdoors or facing the sun and wind should be shaded, and exposure to sun, rain, and wind erosion are strictly prohibited. Painting and winding insulation materials are strictly prohibited on the surface of the joints.
Installation is formal and accurate: when the pipeline displacement is greater than or equal to the maximum compensation of the joint, the number of joints should be increased to parallel the displacement, and it is strictly forbidden to make the joint in the limit of flexural displacement and deviation state in order to adjust the super-difference of the pipeline, not to mention the super-limit.
When installing the rubber joint, the screw of the bolt should be extended to the outside of the joint, and the bolt of each flange end face should be tightened evenly repeatedly according to the method of diagonal pressurization to prevent pressure deviation. Do not use force to make the live joint slip, slide and break, and check it regularly so as not to loosen it and cause the disassembly or media leakage.
After the rubber joint is under pressure for the first time (e.g. installation test pressure, etc.) or before starting again after a long period of disuse, the bolt should be re-pressurized and tightened before putting it into operation.
