Product overview
Angle steel flange is a flange made of angle steel (a type of steel with an L-shaped cross-section). The processed angle steel still maintains its two edges perpendicular at 90 degrees, without flanging or wrinkling.
Product features
High strength: Angle steel itself has high strength, so angle steel flanges also have high load-bearing capacity.
Good stability: The structure of the angle steel flange is stable and not easily deformed, making it suitable for situations that require high stability.
Easy installation: The connection method of angle steel flange is simple and easy to install, which can improve construction efficiency.
Diversity: Angle steel flanges can be customized according to different needs to meet pipeline connection requirements of different specifications and shapes.
Strong corrosion resistance: Angle steel flanges can undergo anti-corrosion treatment during the manufacturing process, such as galvanizing, painting, etc., to improve their corrosion resistance.
Classification
Angle steel flanges can be divided into two types based on their bending direction:
Angle steel positive coil flange: The angle steel is rolled outward, with the opening facing outward.
Angle steel anti roll flange: The angle steel is rolled inward with the opening facing inward.
Craftsmanship
The production process of angle steel flanges mainly includes the following steps:
Material preparation: Select appropriate angle steel materials to ensure their quality and specifications meet the requirements.
Cutting: According to the size and shape requirements of the flange, use a sawing machine or cutting machine to cut the angle steel.
Bending: Place the cut angle steel into the bending machine for bending processing, forming the basic shape of the flange.
Drilling and welding: Drilling holes on flanges for subsequent connection with pipelines or other equipment. Then, use welding equipment to firmly weld the flange to the pipeline or other equipment.
Surface treatment: Rust removal, painting and other surface treatments are carried out on the welded flanges to improve their corrosion resistance and aesthetics.
Application scenarios
Angle steel flanges are applied in the following fields:
Industrial fields: such as petroleum, chemical, water supply and other industries, used in pipeline systems for transporting medium and low pressure liquids and gases, such as oil pipelines, chemical pipelines, thermal pipelines, etc.
In the field of architecture, it is used in steel structure buildings such as bridges and large buildings to connect components such as steel pipes and beams.
In the field of ships, it is widely used in ship pipelines, ship water tanks, and other places to facilitate the connection, disassembly, and replacement of internal pipelines in ships.
Ventilation duct connection: Angle steel flanges also play an important role in ventilation duct systems. They have high strength and can withstand large pressures and weights, making them suitable for situations where high sealing requirements are placed on ventilation systems.
Advantage and disadvantage
Advantages:
Strong load-bearing capacity: Angle steel flanges have high load-bearing capacity and are suitable for situations where they can withstand high pressure and weight.
Reliable connection: The connection between angle steel flanges and pipelines or other equipment is simple and reliable, ensuring the sealing and stability of the system.
Strong corrosion resistance: Angle steel flanges that have undergone anti-corrosion treatment have high corrosion resistance and can be used for a long time in harsh environments.
Shortcoming:
High production cost: Compared to other types of flanges, the production cost of angle steel flanges is higher, especially in large-diameter air ducts, which require thicker and larger specifications of angle steel, further increasing material costs.
The processing difficulty is relatively high: In the actual operation process, it is difficult to achieve that the two edges of the angle steel flange are perpendicular to each other at 90 degrees, without flanging or wrinkling.
