Qingdao common plate flange air ductThe manufacturer thinks that the ordinary flanged air duct is spiral thin-walled pipe, and the edge is pressed to sew. Its raw material is metal strip, and its process form is rolling. Most of them are used to transport bulk materials and wind. It is a common flange duct without welding, air leakage and water leakage. The whole mechanism straight tube does not need manual beating.

Qingdao common plate flange air ductThe manufacturer thinksOrdinary flange duct is mainly used as follows:

(1) air supply: including ventilation, such as fresh air delivery, exhaust, involving a wide range, such as factory workshop, production site air, because harmful gases need to be discharged to the outside, outdoor air needs to be transported to the room. At this time, large flow and low pressure air conveying pipes should be used, which are suitable for spiral air ducts. Galvanized iron pipes are generally used, and stainless steel pipes are used in corrosive and particularly humid places.

(2) Cold air supply: Qingdao common plate flange air ductThe manufacturer thinksOrdinary pipes of central air conditioning need to add insulation materials. Spiral duct can paste insulation material, the appearance looks very beautiful.

(3) smoke: hotels, restaurants, hotel kitchens produce a lot of smoke, need to be discharged. The circular air duct is mainly an oil chimney. Here, the spiral air pipe should be called fume pipe.

(4) Dust removal:Qingdao common plate flange air ductThe manufacturer thinksSome factories have a lot of dust in the production workshop and require special dust removal devices. Among them, the spiral air duct can be used for pipes with large air volume.

(5) Transport of bulk materials. In the production process of some factories, it is necessary to transport loose particles, especially particles with a small specific gravity, such as foam plastic particles. The use of spiral air duct has low cost and good effect.

Secondly, understand the product characteristics of ordinary plate flange duct. Qingdao common plate flange air ductThe manufacturer thinksCompared with the traditional hand-knock white iron pipe, the common plate flange air duct has the following advantages.

(1) good sealing performance.

(2) Good strength and rigidity.

(3) The ventilation resistance is small, the ventilation noise is small, and the round pipe is better than the square pipe.

(4) Easy installation, few connection points and beautiful appearance.

Qingdao common plate flange air ductThe manufacturer thinksIf it is close to the processing plant or the transportation cost is small, the installation of the air duct bite and the conjoined flange can be completed directly in the factory. Generally taking into account the operating costs, the use of semi-finished processing, on-site installation of bite and conjoined flanges. On-site lofting and biting are generally used for special-shaped pipes. The installation process of the air duct is similar to that of the angle steel flange air duct.

Qingdao common plate flange air ductThe manufacturer thinksThe production of air duct can be customized in the processing plant. In the process of air duct production, the environment is clean, computer lofting, laser cutting, low loss, and flow operation can be formed. The formed air duct has straight folding angle, uniform folding width, circular arc shape, no hole, bite and expansion crack. The air duct shall be reliably reinforced with proper spacing and uniform symmetry.
