GDF flange
former:
Products
Information：
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. Dingcheng knows
flange structure very well, and quite familiar with the standards
of duct pressure test and leakage test, including SMACNA,
DW**4/**2, GB*******7 standards. Dingcheng flange forming machine
can satisfy different requirements in different markets.
Dingcheng 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.
European
standards recommended the use of slide-on flange because of its
strength, hollow double section and the ability to hide the L’
type corner pieces. GDF integrated flange is widely applied in
Europe as a kind of quick installation duct flange. It shares
common advantages with TDF flange—well seal, free of jointing and
rivet. GDF flange is integrated with duct, connect with 4 bolts
and special duct corner and clamp. One side forms GDF flange the
other forms clip. Or roll forming both GDF flanges in one machine
as different model numbers.
