Anti-pulling effect of rubber joint installation

Do you know about the anti-pull-up effect of rubber joints ? Today we will give you a brief introduction to this issue.
First, the flange connecting the rubber joint should be a valve flange or a flange conforming to GB / T9115.1 (RF).

Second, the normal applicable medium for flexible rubber joints is ordinary water with a temperature of 0-60 ° C. For special media such as oil, acid and alkali, high temperature and other corrosive and hard textures, the corresponding special resistant Material rubber joint , cannot be used blindly or universally.

Third, when the pipeline medium is acid-base, oil, high temperature and other special materials, a joint that is one gear higher than the working pressure of the pipeline should be selected.

Fourth, the appropriate model must be selected according to the working pressure, connection method, medium and compensation amount of the pipeline, and the number should be selected according to the noise reduction displacement requirements.

Fifth, when the pipeline produces instantaneous pressure and is greater than the working pressure, a joint higher than the working pressure should be selected. (For example: when the instantaneous pressure at the start of the pipeline is> 1.0MPa, a joint working at 1.6MPa should be used. When the instantaneous pressure> 1.6MPa, a 2.5MPa joint should be used).

Sixth, when the flexible rubber joint is used at the inlet and outlet of the pump, it should be located near the pump side, a metal reducing joint should be installed between the pump and the pump, and it should be installed at the large diameter of the reducing diameter.

Seventh, when the pipeline displacement ≥ the maximum compensation amount of the joint, the number of joints should be increased to parallel the displacement amount. It is strictly forbidden to adjust the excess of the pipeline to make the joint in the limit disturbance displacement and deviation state, let alone exceed the limit ( Telescopic, displacement, deflection, etc.), see the table below for specific installation data.

Eighth, after the rubber joint is initially subjected to pressure (such as: installation test pressure, etc.) or before long-term deactivation and re-enablement, the bolts should be re-pressurized and tightened before being put into operation.

Ninth, the high-level water supply or suspended water supply, the pipeline should be fixed on the hanger, bracket or anchor, and the joint can not bear the weight and axial force of the pipeline, otherwise the joint should be equipped with anti-pulling device (its bearing capacity must be greater than Axial force in the pipeline).

Tenth, when the flexible rubber joint is installed, the screw of the bolt should extend to the outside of the joint , and the bolt on the end face of each flange should be tightened repeatedly and diagonally to prevent pressure deviation. The wire joint should be tightened evenly with a standard wrench. Do not use a booster rod to force the loose joint to slip, edge, and break, and check regularly to avoid loosening and water leakage.
