Special white iron processing scissors, square hammers, files, pliers, tweezers, angle rulers, steel rulers, white iron shears, pipe cutters, electric rolling machines, white iron wire presses, white iron bucklers, and electric welding machines, angles, etc. are also used to weld air duct racks. The white iron processing is relatively simple, and ordinary manual processing can stop the white iron processing.
II. The main items in the industry are:
1. White iron pipes: white iron thick iron various exhaust, exhaust and dust absorption pipes, central air conditioning cold air pipes, white iron ventilation pipes, kitchen smoke extraction pipes, insulation pipes, paint stoves smoke hoods.
2. White iron engineering: hotel restaurant supermarket engineering, workshop ventilation engineering, industrial (factory) ventilation (ventilation) purification engineering, water curtain cooling engineering.
3. External processing: plate shearing, folding, stamping, hydraulic.
4. Consumption and sales of processing with supplied materials or customized products: all kinds of metal white iron products, aluminum plates, stainless steel and all kinds of square and round products, water closet, stainless steel workbench, shelf, water tank, vacuum bucket.
The application of new technology and equipment of common plate flange connection characterized by the innovation of white iron air duct structure has promoted the scientific development of metal air duct processing skills.
The traditional connection between the white iron air duct sections is the process of connecting the pipe sections with multiple bolts after the angle steel or flat steel flange and the pipe end are fixed by flanging, riveting or welding.
The new process of common plate flange air duct connection is a new process that uses the rolling forming principle to roll out the flange shape at both ends of the air duct, and then combines the air duct sections through flange corner pieces and flange clamps.
The primary process of white iron air duct processing is seaming processing and flange manufacturing. Because angle steel (flat steel) flange manufacturing is labor-intensive, material consuming, long processing cycle, and many quality assurance links, it has constantly become the primary factor limiting the construction power and quality of the ventilation and air conditioning system. The new process and equipment of common plate flange air duct with self formed flange of air duct body instead of angle steel (flat steel) flange are recognized and selected by relevant units and personnel in design, construction and inspection of the industry once they are introduced due to their outstanding process characteristics.
