The service life of rubber expansion joints is related to those factors? Material is important
First of all, to understand the role of rubber joints, rubber joints are able to achieve the connection and compensation of unequal pipeline systems, achieving the purpose of using the connection and compensation at the same time in one application in the pipeline system, which can reduce the noise generated by the vibration of pipelines such as pumps after installation, with strong vibration absorption capacity.It can absorb lateral, axial and angular displacements generated by pipeline vibration; it is not limited by the fact that the pipes are not concentric and the flanges are not parallel.
Rubber joints use a variety of synthetic rubber materials to process and produce the product, which has excellent reliability and can effectively cope with corrosion in various environments and internal corrosion of the pipeline compared to metal connection pipeline fittings, which systematically meets the needs of various pipeline projects.
The multi-displacement function of rubber joints is integrated, which can not only freely mechanically expand and contract during installation and disassembly for maintenance, but also compensate for linear expansion and contraction of the pipeline due to temperature changes and compensate for the different centering of the pipeline due to foundation settlement and other causes of angular deflection, as well as eliminate the transmission of vibration and noise, making it a multi-functional pipeline compensator.
Rubber joints are made of internal seamless high-pressure rubber joints, which are more effective in preventing the erosion of corrosive media on the inner wall of rubber joints in pipelines that are resistant to high temperature, acid and alkali, and oil, and improve the service life. It is mostly used for the flexible connection of metal pipes conveying liquids, gases, solids and other materials.
In addition to the quality of the rubber joint itself, and the installation environment, whether the correct installation also has a great connection, I will talk about the installation and use of pipeline shock absorbers requirements. When installing, the correct type of rubber joint should be selected, the compensation and displacement of the joint should be equal, not greater or less than, and the rubber joint should be in natural condition during the installation, not artificially deformed.
When installing rubber joints, the screw of the bolt should be to the outside of the joint, and the bolt of the flange end should be tightened evenly according to the diagonal pressure method, not to press the deviation.
If the medium environment changes, such as temperature increase, environment becomes acidic, alkaline, oily environment, etc., you need to use the corresponding rubber joints, such as high and low temperature rubber joints, acid and alkali resistant rubber joints, oil resistant rubber joints.
Rubber joints contain rubber, the environment should be in a cool and dry environment, if the installation in the open air, exposure to the sun environment, the normal use of rubber joints are harmful.
