How to choose proper flexible rubber joint in practical application

Flexible rubber joint has many different names, generally can also be called flexible flexible rubber joint, flexible rubber joint, rubber expansion joint, etc. Flexible rubber joint, as the name suggests, is a kind of joint used in pipe connection, the material of the main body is rubber, at the same time with flange, clamp and other parts. Because rubber has many excellent characteristics, such as scalable, high temperature resistance, corrosion resistance, flexible rubber joints are widely used in oil, water supply, drainage, power, fire, health and other fields. So in practical application, how should we choose the appropriate flexible rubber joint?

Flexible rubber joint

The first thing to consider is the size of flexible rubber joint, only the size is appropriate, the installation can be successful. In general, the nominal diameter DN of flexible rubber joints is 32mm-3000mm and the length is l95mm-500mm, which will vary according to the actual needs. Secondly, it is necessary to know the working pressure of flexible rubber joints. There are three commonly used ones: 1.0mpa, 1.6mpa and 2.0mpa. The larger the number, the greater the work pressure, i.e. the internal and external pressure that can be borne. If there is an instantaneous increase in pipeline pressure in the actual work, then we should choose a higher pressure than the standard pressure to deal with this situation. Then we need to know the flexible rubber joint connection, generally flange connection, clamp connection and wire buckle connection. When installing flexible rubber joint, it is strictly forbidden to over-limit the displacement and deflection of the joint, otherwise it will cause irreparable damage to flexible rubber joint. If the actual required displacement is greater than the standard displacement, it should be solved by adding joints.

In practical applications, there are still many requirements, such as whether the medium of the pipeline is water or oil, whether the pipeline needs to be acid or alkali resistant, and whether the pipeline needs to withstand high temperature or low temperature. In short, we must choose a suitable flexible rubber joint according to the actual situation.
