What are the use conditions of metal bellows?

What are the use conditions of metal bellows?

The design, manufacture, installation and operation management of Corrugated Metal Pipe compensator. Therefore, reliability should also be considered from several aspects. Choose the bellows used in heating network selection of materials, in addition to its work efficiency, also should consider its medium, the working temperature and external environment, we must also consider the stress corrosion, water treatment agent, the possibility of pipeline cleaning effect material, and on this basis, with corrugated pipe material, welding, forming, material cost and performance, points out the economic and practical production of materials to optimize the bellows.

Under normal circumstances, the steel corrugated pipe used shall meet the following conditions:

(1) high elastic limit, tensile strength and fatigue strength, to ensure bellows work.

(2) good plasticity to facilitate bellows forming and processing, and through subsequent processing (work hardening, heat treatment, etc.) to obtain enough hardness and strength.

(3) good corrosion resistance to meet the requirements of bellows working in different environments.

(4) good welding performance to meet the requirements of welding process in the production of bellows.

For ditch laying heat pipe network, when in low-lying pipe, rain or unexpected sewage will be soaked bellows compensator, should consider such as iron more corrosion resistant materials, choose nickel alloy, high nickel alloy and so on. As the price of this material rises for bellows manufacturing, we can consider an additional corrosion-resistant layer of surface alloy only in contact with corrosive media. The type of Spiral Corrugated Culvert fatigue life and the reasons for failure analysis design of the compensation can be seen, this aircraft bellows stability, stability and corrosion cycle two pairs of displacement amount is with anti-fatigue life. Too low will lead to lower stability and corrosion resistant metal bellows fatigue life.
