How to install the rubber flexible joint in the pipeline without water leakage
In such a rapidly developing society, various pipelines under the road had begun to be unable to accept the vibration brought by various vehicles on the road, and not only these, so a product called rubber flexible joint was invented. Its function is to make the compensation of long spacing pipes connected, with the characteristics of displacement compensation, vibration reduction and noise reduction, similar to that of rubber shock absorber.
Rubber flexible joints are commonly used in drainage pipes, seawater desalination pipes, ship pipes, fire protection pipes, sewage disposal pipes, etc. These alone illustrate that the rubber flexible joint must have the characteristics of corrosion resistance, upper and lower temperature resistance, and friction resistance to make the pipeline run safely for a long time.
How can the rubber flexible joint be installed to ensure no water leakage in the pipeline? First of all, we must know why it leaks and where the device is bad. The rubber joint products generally adopt flange connection. During the flange connection process, the protruding rubber edge of the rubber end face of the rubber joint itself shall be used as the sealing information to seal the flange end face of the rubber joint. Therefore, the rubber joint in the buckle groove is prone to water leakage, while the fully sealed rubber joint on the end face will not, The main reason is that the grooved rubber joint device does not well clip the rubber sealing end face into the groove of the flange, so that the rubber joint is prone to suffer from partial pressure concentration at the edge and leakage during the use. The correct device is as follows:
1. During the installation of the rubber shrink joint, the rubber part must be well buckled into the flange groove;
2. Do not tighten the bolt too hard. Since tightening the bolt will crush the sealing surface at the rubber edge, the sealing surface will be broken, and the rubber ball will be scrapped locally. If this situation occurs, loosen it a little.

Application of silicone tape in non-metallic compensator
Literally, the main material of the tube body forming the contraction joint is fiber fabric or other special non-metallic materials.
Product characteristics:
(1) Compensated thermal shrinkage: non-metallic contraction joints can provide larger multi-dimensional direction compensation in a smaller size range.
(2) Compensating device error: because system error is unavoidable in pipeline connection, non-metallic contraction joint can better eliminate device error.
(3) Noise elimination and vibration isolation: fiber fabrics and thermal insulation cotton can absorb sound and isolate vibration transmission, which can effectively reduce the noise and vibration of boiler, fan and other systems.
(4) No reverse thrust: Since the main material is fiber fabric, it is unable to transmit. The use of non-metallic contraction joints can simplify the design.
(5) Good sealing performance: under the action of various media, it has good sealing performance. The device is easy to maintain.
