What are the functions and uses of metal bellows

Metal bellows is a kind of pipe with regular wavy appearance. Common metal bellows include carbon steel, stainless steel, steel lined plastic, aluminum, etc. It is mainly used for the connection of pipes and pipes, or for the connection of pipes and equipment, where the small bending radius is required for non-concentric axial transmission, or irregular turning, expansion, or absorption of thermal deformation of pipes, or where the installation of fixed elbows is not convenient.

Metal bellows blank is the ideal matching product for metal hose, bellows, bellows compensator, bellows blank, automobile exhaust pipe, high-pressure hose, threading pipe and other pipe bodies. Use metal bellows blank. It is divided into soft, hard, bright and soft varieties, with reliable quality and complete specifications. The product is corrosion resistant, clean and beautiful, can increase the pressure of the finished hose, withstand high and low temperatures, extend the service life of the pipe body, and reduce costs. It is widely used in machinery, chemical industry, metallurgy, construction and other industries.

Metal corrugated hose (metal corrugated pipe blank) is a high-quality flexible connecting pipe in modern industrial pipeline. It is mainly composed of metal bellows, metal mesh and various joints. The inner pipe is a thin-walled stainless steel corrugated pipe with spiral or ring corrugation, and the outer net sleeve of the corrugated pipe is woven by stainless steel wire or stainless steel belt according to certain parameters. The joints at both ends of the hose shall be prepared according to the joint form of the user's pipe or equipment.

Advantages of using metal bellows:
1. Double seal design (bellows+packing) If the bellows fails, the valve stem packing can also avoid leakage, which conforms to international sealing standards.
2. Safety and environmental protection, no fluid loss, reduce energy loss, and improve the safety of plant equipment.
3. Long service life, reducing maintenance times and operating costs.
4. Robust and durable bellows seal design ensures zero leakage of valve rod and provides maintenance-free conditions.
