A Study on the Structural Form of Sealable Duct Flange
A structural form of sealable duct flange is proposed to address the shortcomings of the use of angle steel flanges in airtight air ducts,such as the inability to ensure the bonding effect of the end face,low reliability of airtight measures and lack of consolidation measures,so as to solve the problems of increased construction costs and welding and design difficulties caused by casing welding,ventilation enclosure and duct diversion.The flange of this structural form adopts the measures such as integral forming,annular sealing groove,flange gasket,and factory tightness test,which can solve the airtight problem after flange connection.It effectively reduces the difficulties of welding and design on the premise of facilitating construction and improving the overall tightness of the airtight air duct.
