Large wind pipe flange plate production line - Hao Feng line offers a variety of air conditioning duct. Direct sales hotline: 13573487358 Texas Hao Feng Feng Kai air conditioning air conditioning is renamed under a company. Its advanced equipment and technology class. Production of fans, air duct, air crew, air conditioning equipment and other central chassis and accessories sold throughout the country large and small projects. Duct flange plate, also known as flangeless duct, its production in the form of more efficient than the traditional rectangular duct processing speed, more convenient and less common flange leakage rate pictures. The advantage is saving material, reduce engineering investment; a small amount of air leakage, reduce energy consumption, save operating costs, popular construction enterprises welcome. Flange plate mainly by Corner, flange clamps, and one with the wind pipe flange connected connection duct Although this form of low cost (reducing the amount of angle iron, reducing the amount of manual production angle flange), However, the practical application of it is better angle flange firmly, air leakage is large, and must be processed by the machine, handmade hardly achieve its production, usually applied only to new air system, air conditioning system, exhaust system, or often with angle flanged duct. Flange plate production: standard straight line from the direct compression flange piece. Non-standard pipe, after elbow, tee, cross, accessories, cutting, complete TDF flange forming on a single device. Flange angle by direct stamping die, when you can install the card in the four corners. Connection between flanges with Falanca, from galvanized steel production, after Falanca molding machine cut uniform sizes for installation connections. TDF Flange fused steel pipe because, 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, improved efficiency, appearance smooth, accurate size, interchangeability strong, stable product quality.
