The common plate flange is mainly connected by corner code, flange clamp and flange integrated with air duct. It is a kind of galvanized iron sheet air duct.
Although the cost of this type of air duct is low (reducing the consumption of angle steel and reducing the manual consumption of making angle steel flange), it is not as firm as angle steel flange in practical application, and the air leakage is also large.
And it must be processed by machine tools. It can hardly be made by hand. It is usually only used in fresh air system, air conditioning system, etc. the smoke exhaust system is still an air duct often connected with angle steel flange.
Galvanized iron sheet ventilation pipes of air conditioning pipes include normal temperature pipes and refrigeration and heating. The temperature change is small and will not cause pipe deformation.
The galvanized iron sheet pipe for smoke exhaust is a high-temperature pipe. The common plate flange connection will cause deformation and air and smoke leakage. Therefore, the flange is required to have sufficient strength and can not deform for 30min at high temperature
