TDF Flange Duct Manufacturing And Installation Procedure

TDF flange duct is also known as no flange duct, its production form than the traditional rectangular duct processing speed is faster, more convenient, less air leakage rate, the characteristic is to save material, reduce the engineering investment;Small leakage, lower energy consumption, saving operation cost, is popular with construction enterprises.Do you know the production process of TDF flange duct?Let's go and have a look!

The standard straight pipe is directly pressed into a conjoined flange on the assembly line.Non - standard straight pipe, elbow, three - way, four - pass, accessories and so on, complete TDF flange forming machine on single machine equipment.
The flange Angle is formed directly by the mould, and it can be stuck in four corners when installing.Flange connecting flange card, made of galvanized steel plate, cut into a uniform size after the flange card forming machine to be used for installation and connection.

The TDF common plate flange is connected with the pipe steel plate, and it does not need to be riveted like the Angle steel flange. It is connected with a special flange card on the connection of the two sections, and the four corners and 90 degrees flange Angle are connected with bolts.Simple operation, improved efficiency, smooth and smooth appearance, accurate size, strong interchangeability and stable product quality.
