Non-metallic compensator using environment

Non-metallic compensator using environment
The advantages of non-metallic compensator are simple installation, large radial displacement, no rigidity, small thrust on equipment and space saving. Non-metallic compensator is suitable for pipeline or equipment. It is an important component to compensate the displacement of pipeline and equipment, absorb vibration and reduce noise. As a method of thermal compensation and vibration damping, non-metallic compensators have been widely used in pipelines. Although non-metallic compensator is a weaker link in pipeline, it should be strictly controlled in pipeline design and non-metallic compensator manufacturing. The service life of the pipeline system can be fully realized. By using non-metallic compensators, it is possible to use non-metallic compensators in pipeline systems.
The non-metallic compensator is generally composed of fiber fabric skin, heat insulation material, metal structural members, etc. The skin is used to absorb the stress generated in the pipeline or equipment. Different systems in the medium temperature is different, for the use of high temperature working conditions environment for ordinary type of non-metallic compensator can not meet the working requirements, after installation and can not reach the required service life. The non-metallic high temperature compensator adds a reducer structure on the basis of the common type, which is filled in the cavity formed by the skin, frame and guide barrel through the built-in thermal insulation packing. Alternatively, the furnace charge is cast by installing palladium nails inside the guide barrel to adapt it to the high temperature use environment. The skin as the main compensation element of the non-metallic compensator, its construction, material and profile shape should meet the requirements of the pressure, temperature, vibration and sealing of the used medium, as well as the pipeline interface and installation environment. Need to choose the matching material according to the temperature and the nature of the medium. The thermal insulation packing layer of the selected non-metallic high temperature compensator is needed to prevent the accumulation of dust or particulate matter in the cavity, thermal insulation to relieve the medium temperature on the skin and metal frame. When the medium has a pressure pulse, the skin plays a role in supporting vibration damping, and can absorb noise.
