What's the first thing to use when using improper rubber joints?

Jul. 10, 2019

When the rubber joint is used, the most common problem is that there is a problem with the flange attached to it. For example, during the installation of the rubber soft joint, the flat welding flange matched on the opposite side is a large-diameter flange, then, It will be very easy to have problems. This will cause the pull of the rubber soft joint. The reason is because the sealing surface of the matching flat welding flange is not completely sealed with the sealing surface of the rubber soft joint, that is, the inner diameter of the matching flat welding flange is larger than the inner diameter of the rubber soft joint, and it is much larger, so The seal surface is not matched, causing the tow phenomenon. The correct method should be to use the butterfly valve special flange, the inner diameter is the same as the inner diameter of the rubber soft joint so that the pull of the rubber soft joint will not be broken.

Flexible rubber joints are mainly used for lifting and conveying raw water and sewage, water supply and cooling circulating water of thermal power plants, metallurgical industry, condensate, pipeline transportation of chemical substances in the chemical industry, cooling in the petrochemical industry, thinner and other industries Flexible connection between pipelines. Because rubber has high wear resistance, it is also suitable for low-temperature transportation of granular and powdery and gas in all industries.

Besides, remind everyone that it must be noted that the rubber joint is not allowed to be installed at the time of installation. When the rubber joint is installed flat on the ground, suspended, and vertically installed, the actual working axial displacement pressure of the rubber joint is less than the support force of the pipeline. Otherwise, the anti-pull device should be installed to prevent the pressure pull when working. The pipe must have a fixed bracket or a force bracket, and the force of the fixing bracket must be greater than the axial force. For vertical installation and overhead installation, the corresponding fixing bracket and force bracket shall be installed at both ends of the product to prevent the work from being pulled off after being pressed. When installing the bolts, tighten them symmetrically and gradually to prevent partial leakage. Keep away from heat sources during installation and use media that does not meet the requirements of this product.
