Welcome to inquire! Contact: Zhang. Installed in the smoke ducts of corrugated compensation in addition to meet normal operating temperature of the outer margin still should consider the temperature 50 ℃ to meet the requirements of accident conditions. Installing the hot aisle corrugated compensation in addition to satisfying the normal operating temperature outside is still to be considered 20 ℃ temperature margin to meet the requirements of instant over-temperature condition should be able to withstand the pressure required for 120% of positive and negative pressure. bellows compensation device is piping hot fluid, primarily for paved straight pipe. For hot water, steam, oil media, sports Buried compensator by external sleeve slip sliding sleeve, to compensate for thermal expansion. Bellows are suitable for medium pressure ≤2.5MPa compensation works, medium temperature -40 ℃ ~ 600 ℃. Using the new flexible graphite sealing material ring sleeve valve compensator, which has high strength, low coefficient of friction (0.04 to 0.10) metal tube compensation, not aging, effective, easy to maintain.
