Spherical compensators are widely used in superheated steam thermal pipelines

Thread Content

When selecting a spherical compensator, the following factors should be taken into account: 1. Dimensions – the nominal diameter of the hose, the type of connection to be used (mainly flange connection, threaded connection, quick-connect connection), as well as the length of the hose. 　　2. Temperature: The operating temperature and range of the medium inside the flexible hose ； The ambient temperature at which the hose is in operation. At high temperatures, it is necessary to determine the pressure after temperature correction using the correction factor for the operating pressure and temperature of metal bellows at high temperatures, in order to select the appropriate pressure rating. 　　3. Medium: The chemical properties of the medium transported through the hose determine the material of various components of the hose, based on the corrosion resistance parameters of the hose material. 　　4. The pressure is determined by the actual operating pressure of the hose. 　　The spherical compensator is a new type of thermal expansion compensation device for pipelines that features high compensation capacity, small space occupation, cost savings, energy conservation, and safe and reliable operation. It is particularly suitable for high-temperature thermal pipelines, and deserves widespread adoption in such applications.
