High quality pvc bolt joints ductile iron pipe universal expansion joints
Product Introduction
Wide-range compensation joints, also known as universal joints, are widely used mechanical compensation equipment and play an important role in the transmission system. The main principle is to communicate between the two devices and compensate for the displacement offset of the device through a flexible interface.
Product Role
1. Compensate for displacement: In the piping system, displacement or deformation may occur due to temperature changes, earthquakes, or mechanical vibrations. A wide range of flexible compensating joints can compensate for these displacements through their flexible design and material properties, thereby reducing stress and stress on the piping system.
2. Absorb vibration and noise: The flow of fluid in the piping system will produce vibration and noise. A wide range of flexible compensating joints can absorb these vibrations and noises, reduce impact and damage to pipes and equipment, and improve the stability and comfort of the piping system.
3. Alleviate pipeline stress: In the pipeline system, due to factors such as connection between different pipes, temperature changes and medium flow, the problem of stress concentration will occur. A wide range of flexible compensating joints can disperse and alleviate these stresses, reduce the stress concentration of the piping system, and reduce the damage to pipes and equipment.
4. Adjust Pipe Alignment: When installing and maintaining a piping system, alignment issues between pipes may occur. A wide range of flexible compensating joints can adjust the alignment of the pipe and maintain the balance and stability of the piping system through its flexible design.
