Duct Flange Former also called flange former,flange forming machine

 

There are mainly two kinds of flange systems of duct connection. American standard and European standard, which is TDF flange recommended by SMACNA association and TTF/LT mate flange as well as improved GDF flange recommended by British Refrigeration Association. Comifo knows flange structure very well, and quite familiar with the standards of duct pressure test and leakage test, including SMACNA, DW144/142, GB50243-97 standards. Comifo flange forming machine can satisfy different requirements in different markets.

Comifo flange machine adopts heavy duty underpan, arc welding frame, high grade motor, high precision bearing, thermal refined and grinded roll shafts. Its reliable transmission system is free of maintenance. The surface panels have been spray painted. 

 

TTF/LT mate flange has well seal, strong and durable joint structure. Therefore it is specially suitable for producing a duct with large sectional area.

>15 forming stations produce an integral flange

>Manufacturing speed of approximately 26FPM(8m/min)

>Consists of a manual decoiler, rollforming machine and cutting unit

>Cut to length without burrs

>Optional  sealant injection device
