Spiral air duct is a thin pipe made of metal strip coils with spiral bite, circular and non welded shape. It is mostly used for air supply and fresh air flow transportation, replacing the previous white iron pipe (i.e. manual bite iron pipe) as one of the ventilation pipes.
The type, full function, circular pipeline does not require manual tapping, and the installation program of the spiral air pipeline significantly reduces the connection points between the pipeline and the pipeline, reducing the leakage of the connection part of the spiral air pipeline to a small extent, which is a typical spiral air pipeline.
The processing length of ventilation ducts is 3-6m, while the length of ordinary square ventilation ducts is only 1-1.5m; Connecting two spiral air ducts only requires one pipe joint, while in the past, the connection of rectangular ventilation ducts often required a vertical double flange system.
The processing of stainless steel Jinan ventilation ducts can be divided into circular and rectangular shapes. We can produce finished ventilation ducts of various shapes, specifications, models, and plates according to the different requirements of the engineering site. Finished stainless steel pipes have excellent physical and chemical properties such as corrosion resistance, heat resistance, and high strength. Ventilation pipes are mainly used in various process exhaust systems with high airtightness requirements, solvent exhaust systems, organic exhaust systems, exhaust gas exhaust systems, and outdoor parts of ordinary exhaust systems, wet and hot exhaust systems, exhaust dust removal systems, etc.
Ventilation pipeline processing
Precision bite forming process: The molds used for large equipment are all of special steel structures. Even after five years of safe use, the surface of the pressing mold remains unchanged, ensuring that the surface of the galvanized iron sheet is not damaged. The damage greatly prolongs the service life of the ventilation pipe. In addition, the board seam is smooth, tightly occluded, with strong connection force and good sealing performance.
The exquisite spiral pressing steel bar processing technology endows the spiral air duct with excellent strength to withstand pressure. With the addition of spiral steel bars, the thickness of the bite seam plate is four times that of the pipe body, and the pipeline has a high degree of rigidity, demonstrating its sturdy and special ability to withstand large pressure loads without damage or deformation. The thickness of the material plate can be reduced by 15%, saving costs.
