1、 Introduction to Stainless Steel Spiral Duct Factory

Nanjing Hangyao Ventilation Equipment Co., Ltd. aims to produce first-class products and create high-quality projects. In the process of development, we have made steady progress, based on excellent product quality, stable economic strategies, and solid market development, to achieve long-term stable development of the enterprise. We are a high-tech environmental protection enterprise specializing in the research and development, production of ventilation and cooling equipment, and undertaking ventilation and cooling projects. The company adheres to the business philosophy of "product innovation, quality first, service first, and customer trust".

2、 Advantages of Stainless Steel Spiral Duct Factory

1. Strict selection of raw materials: High quality stainless steel and pure iron sheet are carefully selected for the production and manufacturing of air ducts. The materials are sturdy, aesthetically pleasing, and the inner walls are smooth. The surface of the iron sheet is passivated with zinc coating to improve its protective and decorative properties.

2. Craftsmanship: Stainless steel is reinforced with ribs through automatic production lines, inner wall reinforcement drilling, common plate flange drilling, laminating to square forming in one go. Angle steel flange air ducts are also matched with standard hole flanges for easy installation.

3. Precision quality: The product undergoes over 20 strict inspections and nearly 50 standards, with layers of checks and multiple channels of control including initial inspection, re inspection, and full inspection, ensuring a 99.9% pass rate for product use. The mechanism bite has no air leakage and good airtightness.

4. On demand customization: We can provide one-stop solutions according to customer requirements, from surveying and drawing to batching and construction installation. We can customize various specifications of air ducts, which are easy to operate, time-saving, labor-saving, and worry free.

3、 Scope of application of stainless steel spiral air duct

Stainless steel spiral air ducts have a wide range of applications and can be specifically distributed in purification system return air ducts, central air conditioning ventilation ducts, industrial air supply and exhaust ventilation ducts, environmental protection system suction and exhaust air ducts, mining gas drainage pipes, mining coated cloth air ducts, etc.

4、 Construction conditions for stainless steel spiral ducts

1. The basic maintenance and support structure construction are completed, and any obstacles that may hinder the construction are cleaned up. The ground is kept clean and free of debris.

2. The reserved hole size is correct, without any omissions, and is 100mm larger than the actual cross-sectional area of the air duct on each side.

3. The auxiliary facilities in the construction site are complete, such as climbing ladders and scaffolding, construction power supply and safety protection devices（Such as safety nets, safety ropes, safety helmets, etc）Including firefighting equipment, etc.

4. The installation of spiral ducts should include construction plans and design drawings, as well as guidance and on-site emergency plans for the quality, technical, and safety requirements of construction personnel.

5、 Cleaning method for stainless steel spiral air duct

1. Vacuum suction: Use a handheld vacuum suction tube to operate. Use a brush to directly contact the inner wall of the pipeline to remove dirt. This method requires a large inspection hole in the air duct so that operators can access it as much as possible, but it is more likely to miss some dust and dirt because the air duct cannot form a complete negative pressure condition. The following methods can create negative pressure conditions.

2. Power scrubbing: Use pneumatic or electric brushes to scrub dirt, and then the dirt is sucked into the vacuum collector using the same method and direction as gas flushing. This method requires as much care as possible not to damage the appearance of the insulation material.

3. Gas flushing: This method uses a hose with a nozzle connected to the air duct to deliver compressed air. Design the nozzle so that compressed air can drive dust and dirt in. The dirt and dust dried by compressed air are transported along the air duct to the vacuum collection container.
