The packing type compensator sets two sections of pipe together, and the gap in the middle is sealed with flexible packing and tightened with a gland. Both ends of the compensator are connected to the pipeline with flanges to eliminate damage to the pipeline caused by thermal stress caused by temperature changes. Spherical compensators mainly rely on the angular displacement of the sphere to absorb or compensate for the lateral displacement of the pipeline in one or more directions. The compensators should be used in pairs. A single spherical compensator has no compensation capability. Can be used as a universal joint for pipes. This compensator has a large compensation capacity. No blind force. The force on the fixed pipe frame is small, and the seal adopts injectable combined sealing technology to achieve long-term reliable sealing.
Square compensator, also known as natural compensator, is the earliest compensation method adopted in China. Generally, steel pipes are welded or pressed, and the displacement of the pipes is compensated by bending the steel pipes.
The bellows compensator is assembled by welding and welding stainless steel bellows, pipes and flanges. As long as the expansion and contraction of the bellows is used to absorb the deformation of the compensation pipe, in recent years, the corrugated compensator has completely replaced the square compensator.
Rotary compensator is a new type of compensator for thermal expansion compensation of thermal pipelines. The structure of the rotary compensator mainly consists of the integral sealing seat, sealing gland, large and small heads, anti-friction centering bearings, sealing materials, rotating cylinder and other components. When installed on the thermal pipeline, two or more groups are required to form a relative The rotation absorbs the thermal displacement of the pipeline, thereby reducing the stress on the pipeline.
The above is the classification introduction of compensators. If you want to know more about compensators, call us, or come to the factory for on-site inspection and visit. We sincerely welcome customers to visit us.
