There are many names for flexible rubber joints, in addition to rubber joints, there are also a series of names such as rubber soft connections, rubber shock absorbers, rubber shock absorbers, etc. The wide range of uses of rubber joints can be seen from the multitude of names. Rubber joints are mostly installed inside pipelines, which not only have a small repair effect on the inclination of the pipeline, but also have a shock-absorbing and noise reducing effect on the pipeline, making them very practical pipeline connectors. With the widespread use and large-scale installation of rubber joints, some rubber joints that have been damaged under non-standard operation have gradually emerged. The reasons are also varied. Below, we will talk about the abnormal state of rubber joints after being damaged.
1. Leakage situation: The occurrence of leakage situations mostly comes from non-standard installation. During installation, tightening screws is a process that must be taken seriously. The diagonal tightening method cannot be changed, otherwise local sealing may not be tight, leading to leakage of rubber joints.
2. Pulling situation: This situation is caused by the actual stretching of the installed pipeline exceeding the maximum stretching length of the rubber joint, resulting in the flange being forcibly pulled out from both ends of the sphere. In this case, please replace the double sphere rubber joint in a timely manner for use, or you can also use a limiting device in the rubber joint. In addition to having certain specifications for the stretching of the rubber joint, the limiting device also greatly improves the vibration of the pipeline.
3. Immersion deformation: This situation occurs on ordinary rubber joints installed in oil pipelines. Due to the corrosive effect of oil rubber, prolonged immersion can cause swelling of the rubber joints, leading to sealing problems and a decrease in their own quality. Therefore, oil resistant rubber joints must be selected in oil pipelines.
4. Dimensional deformation: Dimensional deformation comes from the strong twisting degree of the pipeline. Due to the large inclination of some pipelines, they may become twisted during transportation. Rubber joints are a particularly pressure resistant product, but they are helpless in dealing with twisting situations. In this case, please replace the rubber joints with high-pressure resistant rubber joints.
