The corrugated pipe has good plasticity, which is convenient for processing and forming of stainless steel corrugated pipe, and can obtain sufficient hardness and strength through subsequent processing processes (cold work hardening, heat treatment, etc.).
The principle of the rotary compensator promotes energy conservation and environmental protection and promotes the healthy development of the environmental protection industry. Suggestions for the development of bellows compensators.
The steel frame wound four-layer stainless steel spiral corrugated pipe is a new type of corrugated pipe with high-density polyethylene as the basic material, and the outer spiral wound wall layer lined with steel plates to strengthen the hollow reinforcement.
The bellows expansion joint is a device with a telescopic function composed of a metal bellows and a component. It can compensate for thermal deformation, mechanical deformation of the pipeline, and absorb various mechanical vibrations, and reduce the deformation of the pipeline and increase the service life of the pipeline.
[Abstract] The characteristics, compensation types, advantages and disadvantages of the metal bellows expansion joints in direct-buried heating pipelines, their advantages and disadvantages, the setting steps, and the matters needing attention in design and use are introduced.
The manufacture of metal bellows begins with the selection of raw materials and passes through the main process links such as tube blank manufacturing, bellows forming, shaping, heat treatment, surface treatment, quality inspection, etc.
