1、 Introduction to stainless steel angle iron flange air duct

Stainless steel angle iron flange air ducts, due to their excellent physical and chemical properties such as corrosion resistance, heat resistance, and high strength, are mainly used in various process exhaust systems with high air tightness requirements, solvent exhaust systems, organic exhaust systems, waste exhaust systems, and outdoor parts of ordinary exhaust systems, wet and hot exhaust systems, smoke exhaust and dust removal systems, etc.

2、 Characteristics of stainless steel angle iron flange air duct products

1. Beautiful appearance, smooth inner wall, low resistance, good air tightness, high pressure strength, suitable for very complex exhaust engineering.

2. It can eliminate flammable and non flammable chemical corrosive gases without the need for additional sprinkler fire extinguishing equipment. Made of stainless steel, the material is sturdy and easy to maintain integrity.

3. The internal coating of the air duct has high resistance to chemical acidity and alkalinity, impact resistance, corrosion resistance, and high temperature resistance. It is suitable for temperatures between 150 ° F and 300 ° F (66 ° C~149 ° C).

3、 Preparation before installation of stainless steel angle iron flange air duct

1. The construction of the building envelope structure has been completed, all obstacles and debris have been cleared, and all ground debris has been cleared.

2. When installing the air duct of the purification system, the floor of the internal installation components of the building has been prepared, the concrete leveling of the walls has been completed, and it must be carried out under the condition of ensuring that there is no dust or dust prevention measures indoors.

3. The installation site must have complete auxiliary materials and have construction technicians to provide quality and technical guidance.

4、 Precautions for installation of stainless steel angle iron flange air duct

1. It is strictly prohibited for other pipelines to pass through the air duct

2. The air ducts installed in flammable and explosive environments should have good grounding. The installation of air ducts through living or production areas must be tight, and no air duct interfaces should be installed.

3. The fixation of outdoor vertical air ducts shall not be connected to lightning rods or building lightning protection facilities.

4. The installation of air ducts must comply with the following technical regulations:

(1) The configuration of the connection between air ducts and ventilation equipment and accessories shall not reduce the size of the connecting pipes at their connection points.

(2) Hangers should not be installed at air vents, air valves, inspection doors, and self-control mechanisms, and should not be fixed on flanges to avoid deformation of the air duct and affect its function.

(3) The installation of hangers must comply with the corresponding installation regulations. Suspended air ducts and components should be equipped with fixed points to prevent swinging, such as fixed brackets, supports, etc. The location and quantity of fixed points should be determined according to the system situation.

(4) The material and thickness of the flange gasket vary depending on the temperature of the conveying air.

(5) When air ducts and components pass through walls and roofs, rain covers should be installed. When the air ducts that pass through the roof exceed 1.5m, cables should be pulled, which should be galvanized or made of steel wire rope. The cables should not be fixed on the flange of the air duct and should not be pulled on lightning rods or lightning nets.

(6) The installation of flexible short pipes should be moderately tight and not twisted. The length of flexible metal or non-metal air ducts with stretchability should not exceed 2m, and there should be no dead bends or dents.

(7) The support and hanger of the insulated air duct should be located outside the insulation layer and should not damage the insulation layer.

5、 Maintenance of stainless steel angle iron flange air duct

1. To keep the surface of the stainless steel plate smooth and clean, place it on a spacious and dry moisture-proof wooden cushion frame, and stack it neatly. Stainless steel and aluminum plates should be placed against wooden frames and not stacked flat to avoid scratching the surface during dragging. When cutting, a scratch free marking tool should be used. Wooden hammers or hammers with rubber sleeves should be used during operation, and iron hammers should not be used to avoid rust spots at the drop point.

2. The materials used for flanges should be classified and coded, and rain and snow protection measures should be taken to prevent exposure to the outdoors. Reduce rusting phenomenon. Ventilation ducts should be stacked in a flat and spacious area without standing water. When stacking, they should be numbered according to the system, neat, reasonable, and easy to transport.

3. The handling and loading of air ducts should be handled with care to prevent damage to the finished product.

4. Another thing worth noting is that the paint film should be evenly coated during painting, without any defects such as accumulation, omission, wrinkles, bubbles, or color mixing. Ordinary steel plates must be sprayed with a layer of anti rust paint before crimping to ensure that the seams are not easily rusted. Thin steel plate anti-corrosion paint, executed according to the design.

5. After the inspection of the finished air duct processing products, the connection numbers and project names should be written in the order of the main and branch pipe systems, and stacked and coded reasonably. Waiting for transportation out of the factory.
