Product introduction

Socket Weld (SW) Flanges are a type of pipe flange designed for use in high-pressure and small-diameter piping systems. They are commonly used in applications where leakage prevention and structural integrity are critical. Here are some key features and details about SW flanges:

1. Design:

- SW flanges have a socket-like recess at the base, which allows the pipe to be inserted into the flange before welding.

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

2. Applications:

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

- Commonly used in high-pressure systems, such as hydraulic, steam, and chemical processing industries.

3. Advantages:

- Provides excellent flow characteristics due to the smooth bore and reduced turbulence.

- Offers high structural integrity and resistance to leakage.

- Suitable for high-pressure and high-temperature environments.

4. Limitations:

- Not recommended for corrosive or erosive fluids, as the gap between the pipe and flange can trap contaminants.

- 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!
