Stainless steel rectangular welded air duct is a ventilation duct with a rectangular or square cross-section, made of stainless steel material. Stainless steel has excellent corrosion resistance, high temperature resistance, and good mechanical strength.

Strong corrosion resistance: Stainless steel rectangular ducts can resist the erosion of various chemicals and are suitable for ventilation systems in various harsh environments.
Good high temperature resistance: Stainless steel rectangular ducts can maintain stable performance in high temperature environments and are not easily deformed or aged.
High mechanical strength: Stainless steel material has high strength and hardness, allowing the air duct to withstand large wind pressure and loads.
Beautiful appearance: The stainless steel rectangular air duct has a smooth surface and a beautiful and elegant appearance, suitable for installation in places with high requirements for appearance.
Easy installation: Stainless steel rectangular air ducts have fewer connection points, making installation convenient and saving construction time and costs.

Stainless steel rectangular welded air ducts are used in the following fields due to their excellent performance:
Building ventilation system: used for central air conditioning systems, fresh air exchange systems, etc., to ensure indoor air circulation and improve indoor air quality.
Industrial gas transmission: used in the chemical, food, pharmaceutical and other industrial fields to transmit high temperature, high pressure or corrosive gases.
Environmental engineering: used in exhaust gas treatment systems and emission control engineering to effectively cope with harsh working environments.
Special occasions: such as clean operating rooms and laboratory ventilation and air delivery systems in medical facilities, food processing production lines, etc., where it is necessary to keep products clean and pollution-free.

The manufacturing process of stainless steel rectangular welded air ducts includes multiple steps such as material preparation, cutting, bending, welding, and surface treatment. Among them, welding is a key link that requires the use of appropriate welding methods and parameters to ensure the quality and strength of the weld seam. At the same time, in order to further improve the corrosion resistance of the air duct, passivation treatment or coating with anti-corrosion coating can also be carried out.

In order to ensure the normal operation and prolong the service life of stainless steel rectangular welded air ducts, regular maintenance and upkeep are required:
Regular cleaning: Use a soft brush and vacuum cleaner to remove dust and debris from the surface of the air duct, preventing dust and dirt from affecting the ventilation effect.
Check sealing: Regularly inspect the connections and seals of the air duct to ensure they are intact. If there is any looseness or damage, it should be repaired in a timely manner.
Avoid corrosion: Avoid bringing corrosive substances into contact with the surface of the air duct to prevent corrosion from occurring.
Regular inspection: Regularly inspect the appearance and structure of the air duct to ensure that it is not damaged or deformed, and promptly identify and address any issues.
