Rotary compensator

A rotary compensator, also known as a rotary expansion joint, is a device used in piping systems to absorb thermal expansion, displacement or vibration of pipes. It compensates for axial displacement caused by temperature changes, pressure fluctuations or pipe deformation by allowing the pipe or equipment to rotate. Rotary compensators are usually installed at the corners of the pipe or the part that needs to rotate. They can effectively reduce the mechanical stress of the pipe and equipment and prevent pipe rupture, leakage or other failures caused by excessive stress. The device is widely used in pipeline systems in the petroleum, chemical, electric power, steel, metallurgy and other industries.
