product details
Polytetrafluoroethylene compensator, also known as bellows or expansion joint, can be used to eliminate thermal expansion or displacement caused by climate change or other reasons in pipelines, containers or equipment. It is a type of damper. It can be installed at the inlet and outlet of the pump or at both ends of other high-frequency machinery to reduce or eliminate its vibration, improve the service life and sealing performance of the pipeline. Solved problems that metal compensators cannot solve, reduced enterprise costs, and improved production efficiency.
In addition, it can also be used to absorb deviations between design and actual installation. It has the characteristics of reliable operation, compact structure, strong compensation ability, resistance to corrosion of various media, and long service life.Can provide various compensators for DN25-DN2000 one to nine wavesFatigue frequency: ≥ 5000 times In the pipeline design of petrochemical plants, compensators often need to consider the working conditions of high temperature and high pressure.
Therefore, in the design, the thermal expansion generated by the pipeline should be considered. Generally, priority should be given to using the flexibility generated by the pipeline's own structure to absorb the thermal displacement of the pipeline. When the pipeline system lacks flexibility due to limitations such as engineering operating conditions and equipment layout, compensation devices can be used to absorb the thermal displacement of the pipeline. Due to the strong compensation ability of rotary compensators.
The change in pressure drop management can reduce the operating cost of the petrochemical plant, while the change in stress of the thermal expansion compensator greatly increases the safety of the pipeline system during operation. Therefore, in the design of petrochemical plants, long-distance petrochemical pipeline design has this advantage.
