Product introduction

Socket Weld (SW) Flanges are flanges designed for high-pressure, small-diameter piping systems. The Socket Welding Flange is a commonly used connection component in low- and medium-pressure piping systems. Its design features a pipe inserted into the flange's inner bore, followed by a fillet weld at the pipe end. Because the weld is located on the flange's outer circumference, welding is simple and provides high weld strength, making it a common and reliable connection method in industrial pipelines, petrochemicals, natural gas transmission, and power engineering. Its compact structure and easy installation make it particularly suitable for applications with small pipe diameters and stable pressure requirements. They are typically used where leak prevention and structural integrity are critical. Here are some key features and details of SW flanges:

1. Design:

- SW flanges have a socket-like groove on the bottom that allows the pipe to be inserted into the flange before welding.

- The pipe is then fillet-welded along the outer edge of the flange, creating a secure and leak-proof connection.

2. Applications:

In actual engineering applications, socket weld flanges are widely used in pipeline systems conveying flammable, explosive, and toxic media due to their excellent sealing and structural stability, ensuring safe operation. They are also suitable for long-term use in high-pressure, small-diameter pipelines, effectively reducing maintenance frequency. For businesses, choosing socket weld flanges not only reduces the risk of system leakage but also improves the overall lifespan and operational efficiency of the pipeline. As a key connection and sealing component, socket weld flanges have become an indispensable core element in modern pipeline engineering.

- Suitable for small-diameter pipes (typically up to 4 inches or DN100).

- Commonly used in high-pressure systems such as hydraulics, steam transmission, and chemical processing.

3. Advantages:

- Due to their smooth inner bore and low turbulence, they provide excellent fluid flow characteristics.

- They offer high structural strength and reliable sealing, making them less susceptible to leakage.

- Suitable for harsh operating conditions such as high pressure and high temperature.

4. Limitations:

- Not recommended for use with corrosive or highly abrasive media, as impurities may accumulate in the gap between the pipe and flange.

- More challenging to inspect and maintain compared to other flange types.

5. Standards:

- SW flanges are manufactured according to various standards, such as ASME B16.5, ANSI, and DIN.

6. Installation:

- Proper alignment and welding are crucial to ensure a secure and leak-free connection.

- A small gap (typically 1/16 inch) is left between the pipe and the flange shoulder to allow for thermal expansion during welding.

Socket Weld flanges are a reliable choice for high-pressure piping systems, offering durability and ease of installation in compact spaces. Let me know if you need further details!
