Which pipelines need to choose double spherical rubber joints
Rubber joint is a kind of pipeline displacement compensation fittings. Installed on the pipeline, through its own good elastic deformation, it can achieve good displacement compensation for the thermal expansion and contraction of the pipeline due to the influence of force. It can be mainly reflected in the displacement compensation in axial, lateral and angular directions. In terms of structure, rubber joints can be divided into single sphere rubber joints and double sphere rubber joints. As the name implies, single-body rubber joint means that the ball part of rubber joint is made of a single sphere, which is also very common in the industry. So under what circumstances are double-ball rubber joints used?

The production of double-bulb rubber joints is mainly used in working conditions that require high vibration damping effect for pipelines, such as the import and export of water pumps. With double-ball rubber soft joints, the effect of vibration damping and sound absorption is more ideal than that of single-ball rubber soft joints. The compensation range of double spherical rubber joints for axial and angular displacements is also advantageous; the customer's demand for the length of rubber soft joints. Due to the differences in the expansion joints left in the design of many pipelines, single sphere rubber soft joints cannot meet the needs of pipeline expansion joints in the use of rubber soft joints. This is when a double-ball rubber soft joint is needed to make up for the single-ball rubber joint. Spherical rubber joints are inadequate in terms of installation length and expansion. For users, choosing the right rubber joint is also the key. You should choose the matching rubber joint according to your pipeline installation environment and reserved distance, so that the product performance of rubber joint can be maximized. You can spend less money to solve the problems arising in the pipeline. We keep improving the process design of rubber joints to maximize the value of our products and save the operation cost for our customers, and provide richer and more flexible rubber joint solutions through the optimization and integration of extended models.

Installation method of double-ball rubber joint: 1. When installing double-ball rubber joint, it is strictly forbidden to install beyond the displacement limit. 2. The installation bolts should be symmetrical and gradually tightened with pressure to prevent local leakage. 3. Above 1.6MPa working pressure, the installation bolts should have elastic pressure pads to prevent the bolts from loosening during work. 4. When installing vertically, the joint pipe should have vertical force support at both ends, and an anti-pull-off device can be used to prevent the workpiece from being pulled off under pressure. 5. 5、The installation position of double spherical rubber joint should be far from heat source and ozone zone. Exposure to strong radiation light and the use of media that do not meet the requirements of this product are strictly prohibited.6. During transportation and handling of the double spherical rubber joint, it is strictly prohibited to scratch the surface and sealing surface with sharp objects!
