Product Details

1、 Introduction to wholesale of stainless steel angle iron flange air ducts

Stainless steel angle iron flange air duct is a municipal infrastructure designed to facilitate air circulation and reduce the concentration of harmful gases. Ventilation ducts, the boards, profiles, and other main finished materials used in the production and installation of air ducts shall comply with the design and current standards of related products. And the wholesale of stainless steel angle iron flange air ducts involves a large amount of procurement.

2、 Wholesale advantages of stainless steel angle iron flange air ducts

1. Service guarantee: During the cooperative sales and construction period, we will accurately control every small step for our customers, ensuring the timely and high-quality creation of every classic project.

2. High quality raw materials: Cooperating with well-known domestic steel companies, the plates are thick, corrosion-resistant, durable, and have a beautiful appearance.

3. Affordable price: Belonging to manufacturer direct sales, it can avoid the price difference earned by intermediaries.

3、 Stainless steel angle iron flange air duct connection

There are two types of stainless steel angle iron flange air ducts: flange connection and non flange connection. Stainless steel angle iron flange air duct is made of angle iron for the flange of galvanized steel plate air duct, and is a type of air duct connection. Generally, large stainless steel angle iron flange air ducts and small air ducts have no flanges. Stainless steel angle iron flange air duct, also known as non flange air duct, has a faster manufacturing process than traditional rectangular air ducts.

4、 Processing flow of stainless steel angle iron flange air duct

1. Pipe cutting:

(1) It should be strictly carried out according to the drawings, and the material should be carefully checked for correct dimensions before cutting.

(2) When cutting, avoid wasting materials.

(3) First, discharge the material as a whole, and then discharge it to control the amount of pipes used.

(4) If stainless steel welded air ducts are used, mechanical or plasma cutting should be used for cutting, while flame cutting can be used for the rest.

(5) The inclination deviation of the incision end face cannot exceed 2 millimeters.

2. Groove preparation: It should be carried out according to the specifications, and the connection is mainly made by welding. If it is a groove for medium and low pressure pipelines, V-shaped should be used. If it is a high-pressure pipeline, a YV groove should be used. The groove processing should be smooth and free of any defects.

3. Welding joint assembly: It is a pipeline assembly, and the pipeline interface needs to be cleaned before that.

4. Pipeline prefabrication: When prefabricating stainless steel welded air ducts, there should be strict prefabrication allowable deviations, and prefabricated components should be numbered according to the specified requirements for quality control.

5. Assembly of pipeline butt welds: The assembly of stainless steel welded air duct butt welds should ensure that the inner wall is flush and the misalignment should not exceed 10% of the wall thickness.

5、 Cleaning method for stainless steel angle iron flange air duct

1. Vacuum suction method: It uses a vacuum suction tube and then manually cleans it. It requires stainless steel ducts to have large inspection holes, but there may be omissions during manual operation, so this method is not commonly used.

2. Power washing method: It uses pneumatic or electric brushes to clean the dirt, and then gathers the dirt together. A vacuum collector can be used for collection, but it requires that the surface of the stainless steel air duct not be damaged.

3. Gas flushing method: Compressed air is delivered through a hose to flush out dirt, which is then transported to a vacuum container where it is concentrated.
