Qingdao common plate flange air ductManufacturers believe that ordinary flange duct technology as a fast flange duct technology, has been widely promoted in Europe. It has the advantages of angle steel flange duct, stronger structural strength, no welding riveting, galvanized sheet production, good corrosion resistance, tight connection, low air leakage rate. The finished air duct has beautiful appearance, accurate size rules, smooth appearance lines, and the air leakage volume is far lower than the national standard. It is conducive to the factory, scale, standardization and automation of ventilation pipe production.

Qingdao common plate flange air duct manufacturers believe that common flanges are non-steel connections, and the connection form of air ducts made of galvanized steel plates can be directly pressed with steel plates to form air ducts and flanges integrally. Advanced manufacturing technology, accurate blanking, low material consumption, stable product quality, faster and more convenient processing speed and smaller air leakage rate. The air leakage is small, which reduces energy consumption and saves operating costs.

　　Qingdao common plate flange air ductThe manufacturer believes that in the factory, 80% of the workload in the whole construction process of ordinary flange air duct project is completed by mechanical equipment according to the process flow (including scraping and blanking, forming, joint and corner, sealing treatment, cleaning treatment, making air duct hanger and hanger rod). Only the air duct connection and hoisting work are left on the construction site, and the on-site construction tools are simple and easy to install. Compared with ordinary angle steel flange duct, the whole system is light in weight, easy to install, time-saving, labor-saving and material-saving. The process can shorten the construction period and save the cost.

Qingdao common plate flange air duct manufacturers believe that before connecting the bolts on the four corners, it is necessary to apply sealant on the flange surfaces of the two air ducts with ordinary flanges. After that, the shear angle size of the four flange surfaces at both ends of the ordinary flange pipe needs to be accurate, otherwise the four surfaces of the flange will be uneven after processing, causing the ordinary flange pipe to be twisted and irregular.

　　Qingdao common plate flange air ductThe manufacturer believes that during the processing, the flange surface of the air duct needs to maintain a 90-degree right angle. Too large or too small will affect the quality of the duct flange, such as duct distortion dislocation, installation and connection inconvenience. It is necessary to use an ordinary flange manual flanging machine or a sheet metal hydraulic bending machine that matches the flange surface of the ordinary flange air duct, and use a special upper and lower mold to fold the air duct and the flange connection surface, otherwise it will affect the quality of the flange surface, Such as flange surface damage and uneven deformation.

1. In the process of reinforcing the angle steel flange duct, it should be arranged more neatly. Only in this way can the service life of the angle steel flange duct be prolonged.

2. When the large side size of the angle steel flange air duct is 630~1000mm, the air duct should be reinforced directly on the production line. The arrangement should be regular and the interval should be uniform. The plate surface of the flange duct shall not be obviously deformed.

3. Qingdao common plate flange air duct manufacturer: the pipeline shall be supported and reinforced with over-line screws, and its special gasket shall be placed on the inner wall of the pipeline for external insulation, while non-insulation or internal insulation shall be placed on the outer wall of the pipeline. The over-the-wire screw shall be placed in the center of the conduit. When the air duct section is large, a wire screw shall be added on each side close to the flange for support and reinforcement.
