[Jie Weinuo recommend to you the star product - a total of flange duct] flange surface is not flat, rectangular flange rotated 180 degrees, with the same specifications of the flange screw holes do not coincide, the inner edge of size or two pairs of diagonal dimension line does not exceed the permissible deviation equal to a total of flange duct processing quota, the impact of duct components normally assembled at the construction site. Small deviations caused during the installation of unnecessary modifications #, drilling; deviation caused by excessive rework and waste. Flange plate production: standard straight line from the piece directly pressed into the flange. Non-standard pipe, after elbows, tees, crosses, accessories, cutting, completed TDF flange forming on a single device. Flange angle by direct stamping die, when you install the card in the four corners can be. Connection between flanges with Falanca, made of galvanized steel production, after Falanca molding machine cut into uniform sizes for installation and connection to use. TDF Flange steel pipe due to fused, do not like the angle flange-like punch riveted on the pipeline connecting the two sections dedicated Falanca, bolted flange rear corners plus 90 degree angle. Simple operation, improve efficiency, the appearance of smooth, smooth co-flange duct, accurate size and interchangeable flange plate duct area calculation, stable product quality Industrial Co., Ltd.
