TDF flange

The TDF flange air duct is also called the flangeless air duct. Compared with the traditional rectangular air duct, its manufacturing speed is faster, more convenient, and has a smaller air leakage rate. Its advantages are to save materials and reduce project investment; the amount of air leakage is small, energy consumption is reduced, and operating costs are saved, which is quite popular with construction companies. Developed countries such as the United States and Europe have adopted the flangeless connection of air ducts since the 1990s. At present, this process has been widely used in various projects.

In recent years, the amount of air ducts, which are an important part of air conditioning and ventilation systems, has been increasing every year, and the requirements for them have also become higher and higher. The advancement of science and technology has made new materials and new processes used in the manufacture and installation of air ducts emerge in an endless stream, and the common plate flange air duct is one of them. TDF flange air duct equipment has become a practical tool for large-scale construction and installation enterprises, and the ability to produce TDF flange air ducts has become an important factor affecting the undertaking of key HVAC projects.

The TDF flange air duct is characterized by its own flange, reducing the weight of the air duct, good sealing performance, beautiful appearance, high strength, quick and convenient installation, and low production cost. The use of a TDF flange duct processing line not only changes the previous duct production from inefficient human labor to efficient mechanical production, but also greatly reduces labor intensity, improves work efficiency, and reduces engineering costs.

Compared with the angle steel flange air pipe, for every 10 square meters of air pipe production and installation, in the same construction period, about 60% of labor can be saved, various steel 30 kg, more than 10 sets of various connection bolts, anti-rust 0.2 kg of paint.

The duct flange is made of galvanized steel, and the amount of galvanized steel is increased by about 4%; the production line is adopted, and the production accuracy and quality are easier to control. In addition, the reduction in the amount of section steel and anti-corrosion engineering reduces the environmental pollution caused by paint, which has better economic and social benefits.

The production of TDF flange air pipe requires a common-plate flange machine, and the production of angle steel flange air pipe requires an angle steel flange production line.

In modern installation engineering, with the advancement of science and technology, new materials and new processes emerge in an endless stream in the production and installation of air-conditioning ducts, and common-plate flange ducts are one of them. The air duct is playing an increasingly important role in installation engineering.

The common plate flange is mainly connected by the angle code, the flange clamp, and the flange connected with the air pipe. Although the cost of this type of air pipe is relatively low (reduce the amount of angle steel and reduce the amount of labor for making angle steel flanges), However, in actual application, it is not as firm as angle steel flanges, and the amount of air leakage is large. It must be processed by machine tools. Hand-made can hardly realize its production. It is usually only used in fresh air systems, air conditioning systems, etc., and angle steel is often used in smoke exhaust systems. Flange connected air duct.

The equipment needed to produce the common-plate flange duct includes a multi-function shearing machine, a multi-function undercutting machine, a multi-function beading machine, a common-plate flange forming machine, common-plate flange supporting folding machine, multi-function corner code Punch with tick code.

The TDF flange production process is below.

1. The standard straight pipe is directly pressed into a conjoined flange on the assembly line.

2. After cutting the non-standard straight pipes, elbows, tees, crosses, accessories, etc., complete the TDF flange forming on the stand-alone equipment.

3. The flange corners are directly stamped and formed by the mold, and the four corners can be clamped during installation.

4. The connection between flanges is made of galvanized steel plate, which is cut into a uniform size for installation and connection after being formed by a flange forming machine. Because the TDF common plate flange is integrated with the pipeline steel plate, it does not need to be punched and riveted like an angle steel flange. A special flange is used for the connection of the two pipelines. The four corners are connected with a 90-degree flange angle and then bolted. The operation is simple, the efficiency is improved, the appearance is flat and smooth, the size is accurate, the interchangeability is strong, and the quality of the product is stable.

There are 5 ways to bite the plate air duct

1. Single flat bite: used for the splicing seam of the plate and the longitudinal joint seam of the air duct.

2. Single vertical bite: used for circular elbows, back and forth bends, and transverse seams of air ducts.

3. Single-angle bite: used for the longitudinal joints of rectangular ducts or parts, as well as the corners of rectangular elbows and tees.

4. Joint angle bite: The use is the same as the third method.

5. Double flat bite and double bite: the same as the second method, because this method is complicated and cumbersome, it is not used much.

The TDF flange air duct is controlled by software equipment according to the needs of the site, and the production equipment is used. When installing the air duct, only the flange angle and the fixed card are required to connect. Therefore, the TDF flange air duct has better overall performance in terms of performance and construction.

In modern installation engineering, in the process of making and installing air-conditioning ducts, more and more new materials and new processes emerge in an endless stream, and the TDF flange ducts described by the editor today are one of them. The TDF flange air duct adopts a fully automatic production line, combined with the world’s numerical control and optical fiber information technology. In addition to the production of galvanized straight rectangular ducts, it can also produce elbows, tees, crosses, etc. Kind of special-shaped duct parts. These equipment components are playing an increasingly important role in installation engineering. The following are the application characteristics of TDF flange ducts:

1. The production line has a high degree of mechanization and automation, which greatly improves the production efficiency and the production accuracy of the air duct, and reduces the project cost.

2. The air pipe is flanged by itself, which reduces the weight of the air pipe. Compared with the traditional angle iron flange, it saves flange steel and connecting bolts and reduces material loss.

3. The air duct has good airtightness, which significantly reduces air leakage, saves energy, and reduces the operating cost of the main engine.

4. The windpipe automatically compresses the ribs, with high strength, a beautiful and clean appearance, and no zinc layer damage.

5. Fast production and installation, reduce labor intensity, improve labor efficiency, meet the needs of modern projects, and improve the competitive advantage of installation units.

The TDF flange air duct is mainly input into the computer according to the diameter and shape of the air duct on the spot, and the equipment is controlled by the program software to discharge. The machine-made TFD flange forming machine is used to form a flange on the air pipe by flanging. Use this equipment to make corresponding connection flange angles. When installing on-site, use flange corners and flange fixing clips to connect the air duct to achieve the purpose of installation.
