How much can the corrugated compensator withstand temperature?
The temperature resistance of the corrugated compensator depends mainly on the temperature resistance of the bellows material. The use temperature of the compensator is -20℃, up to 600℃, and even higher. It needs a variety of temperature-resistant metal materials to meet the use requirements. But the temperature resistance of the material is limited, by the material itself to solve such a large temperature range of temperature resistance is impossible, but also to take other measures to improve the use of expansion joints temperature. Most of the corrugated compensator working temperature below 400 ℃, carbon structural steel, low-alloy structural steel and stainless steel and other materials can be competent.
Other measures when the metal material can not fundamentally solve the problem, you can use the heat insulation approach. Fill different temperature-resistant heat insulation materials between the guide sleeve and bellows to avoid direct contact of high temperature medium with bellows, so that the medium heat is slowly transferred to the bellows, while natural or artificial cooling measures are taken outside the expansion joint to make the actual temperature of the bellows lower than the use temperature allowed by the bellows material. It is also possible to continuously pass steam or air with low temperature between the inflow sleeve and bellows.
