F4 compensator (expansion joint)
Use range:Used to eliminate pipeline, container or equipment due to climate change caused by stretching or for other reasons which led to the expansion or displacement; as a slow vibration sensor, installed in the pump or other high-frequency mechanical import and export both ends to reduce or eliminate vibration; used to absorb the design and actual installation of the deviation.
Excellent performance:Solve metal compensator compensate poor, and poor corrosion resistance, reduce business costs, improve production efficiency: working and reliable. Compact body and strong ability to compensate and improve the life of the pipeline.
