Abstract：
The most practical and reliable way to improve the tightness of the metal duct is to improve the sealing effect of the plate connection. The clearance compensation performance is a continuous and effective condition for the flange connection system in various working conditions. Reveals the leakage mechanism of the air duct angle joint and the flange connection system by a feature study. Puts forward a scheme to improve the tightness of the corner joint of the metal duct and the flange connection system of the metal duct for the first time. Verifies the design scheme according to the engineering test method.
