What is Welded Flange?

A welded flange is a type of pipe fitting used to connect two sections of pipes, valves, or other equipment. It involves two flanges, a gasket, and bolts, where the flanges are typically welded to the pipes, and the gasket is placed between the flanges to create a seal when the bolts are tightened. Welded flanges are critical components in various industrial applications, such as petrochemicals, aerospace, and construction.

Features of Welded Flanges

1. High strength: Welded flanges are known for their high strength, which is crucial for supporting heavy loads and maintaining the integrity of the piping system.

2. Leak-proof: The combination of a gasket and precise welding ensures a leak-proof seal, reducing the risk of leakage and prolonging the service life of the equipment.

3. Ease of installation and maintenance: Welded flanges can be easily installed, removed, and modified, reducing downtime and maintenance costs.

4. Variety of materials: They are available in various materials, such as stainless steel, carbon steel, and alloy steel, to cater to specific requirements in terms of corrosion resistance and thermal performance.
