Characteristics of directly buried bellows compensator
Although the direct acting bellows compensator is the same as the ordinary bellows compensator used in overhead and trench, it is used to compensate the pipe expansion caused by heating, and the stainless steel is made of stainless steel. However, the direct buried bellows compensator and the common ripple compensator must not be confused. Ordinary bellows compensator can not be immersed in sewage, but not directly buried in the soil. The direct buried bellows compensator adopts the measures of isolating the compensator from the water, so as to realize the fully buried directly, so that the life of the corrugated compensator is the same as that of the pipeline.
Metal bellows compensator, bellows expansion joint, also known as wave expansion device, is a kind of pipeline compensation component widely used in the world in recent ten years. In recent years, this new type of component has been widely used in different fields of our country. Directly buried heating pipeline is widely used because of its advanced technology and low construction cost, and the compensation method and compensator of buried pipeline are also developed. The bellows expansion joint used in the direct buried pipeline shows obvious advantages compared with the traditional PI compensator, because of its easy installation, small volume, small footprint and high compensation capacity
