importance of bellows material choice in steel expansion joint

When it semen to fabrication steel bellows expansion joint, the material choice is crucial. The performance of these joint largely depend on the type of material use for the bellows. improper choice can consequence in issue such as unbalance welding, guerrilla corrugation, and surface damage.

bellows material selection must see factor such as the type of flow medium, working temperature, stress corrosion, water treatment agent, and pipe cleaning agent. It is necessity to also return into history welding consideration, material cost performance, and other relevant factors.

steel bellows material should rich person good corrosion resistance, high rubber band limit, fatigue strength, and extension strength. Additionally, it should posse good malleability for easy processing, as well as the ability to defy cold hardening and heat treatment. welding performance is also a crucial factor to consider.

most manufacturer of steel bellows expansion joint typically use stainless steel steel for the bellows material. However, there are assorted type of stainless steel steel available, each with alone temperature and corrosion resistance property. For not-corrosive medium such as water, oil, or gas with temperature between 100 to 200 degree Celsius, SS304 is a suitable choice. On the other hand, for seawater or acidic environment, SS316 or SS316L would be the prefer options.

It is important to supply complete grapevine operation conditions and technical parameter when quest a quotation mark for steel bellows expansion joint. By make so, you can guarantee that the right material is choose for your particular need. For inquiry, you can range out to sale@lanphan.com.
