Features of Class 150 Socket Weld Flange
- Design: The pipe is inserted into the recessed area of the flange, and the outer edge is welded to ensure the strength and sealing of the connection.
- Pressure Rating: Class 150 indicates that it is suitable for systems with a maximum pressure of 150 psi.
- Applications: Suitable for medium to low-pressure systems requiring high-strength connections, such as pipes transporting liquids, gases, and steam.
- Materials: Typically made from carbon steel, stainless steel, or alloy steel to meet different environmental requirements.
- Standard: Complies with the ANSI / ASME B16.5 standard, ensuring consistency in dimensions, pressure ratings, and materials.
The design of the Socket Weld Flange allows the pipe to be inserted into a recessed area inside the flange, which is then welded around the outer edge to secure it. This type of flange is suitable for pipe connections that need to withstand moderate pressure.

FAQ
A Socket Weld Flange is a type of pipe flange designed to allow the pipe to be inserted into a recessed area inside the flange and then welded around the outer edge. It provides a strong and sealed connection, typically used in moderate pressure applications.
The pipe is inserted into the recessed socket of the flange, and the outer edge is welded around to form a strong and leak-resistant connection.
No, Socket Weld Flanges are generally designed for medium to low-pressure systems. For high-pressure applications, other types of flanges, such as Weld Neck Flanges, are recommended.
