Common types of stainless flanges

The function of welded steel stainless steel flange is to butt weld the flange and pipe. The structure is reasonable, the compressive strength is high, the bending stiffness is large, and it can withstand ultra-high pressure, continuous bending and temperature fluctuations, and the sealing performance is reliable.

ASME B16.5 A182 F316L weld neck flanges

Weld neck flanges: The function of weld neck (WN) flanges is to weld the flange directly to the pipe, providing a reasonable structure with high strength and rigidity. They can withstand high pressure, repeated bending, and temperature fluctuations, ensuring reliable sealing performance.

EN 1092 1 forged slip on flanges

SO Flanges: SO flanges are suitable for connecting galvanized steel pipes with a rated working pressure not exceeding 2.5 MPa. The sealing surface of SO flanges can be divided into flat face, raised face, and tongue-and-groove types. They are primarily used in low-pressure systems such as untreated compressed air and low-pressure circulating water, where their main advantage is relatively low cost.

Lap joint flange or loose flange finished in Haihao Group

Lap Joint Flanges: Commonly known as the loose flange, comes in several common types, including the weld ring lap joint flange, the slip-on lap joint flange, and the flared lap joint flange. They are typically used in situations where the medium has low temperature and pressure but is corrosive. In such cases, the part of the flange that comes into contact with the medium is made of corrosion-resistant material, such as stainless steel, while the external part uses carbon steel flanges to achieve sealing.

ANSI ASME B16.5 socket weld flange

Socket Weld Flanges: These flanges are often used in pipelines with a nominal pressure of PN ≤ 10.0 MPa and a nominal diameter of DN ≤ 40.

Integral Flange

Integral Flanges: Integral flanges are generally integrated with equipment, pipelines, fittings, or valves. These flanges are typically used in applications where they are part of the equipment or valve itself.
