Description

1. Description

The Socket Weld Flange is designed for connecting piping systems by welding the pipe directly into the flange. It provides a strong, leak-proof connection, ideal for systems under high pressure and temperature conditions. Socket Weld flanges are widely used in industries like oil and gas, chemical, power generation, and manufacturing for small diameter piping connections. They offer an effective solution for spaces with limited access.

3. Working

The Socket Weld Flange works by inserting the pipe into the socket of the flange and then welding the pipe to the flange. This creates a robust and secure joint for pressure systems. It is suitable for smaller bore pipe systems, providing both mechanical strength and resistance to leakage. It ensures the piping system remains intact under high-pressure environments.

4. Principle

Socket Weld Flanges operate on the welding principle of creating a permanent bond between the pipe and the flange. The socket weld is ideal for systems where high-pressure applications exist because the joint is made without bolts, providing maximum leak resistance. The socket design also allows for a more compact connection compared to flanged joints.

5. Assembly

Step 1: Select the appropriate flange size based on your pipe and pressure rating requirements.
Step 2: Clean the pipe and the inside of the flange socket to ensure smooth and clean surfaces for welding.
Step 3: Insert the pipe into the flange socket. Align the pipe to avoid stresses.
Step 4: Use TIG or MIG welding to weld the pipe to the flange. Ensure uniform weld bead around the socket.
Step 5: After welding, allow the joint to cool and inspect for defects or cracks.

6. Installation Process

Preparation: Ensure all components are clean, free of rust or debris, and check for compatibility between the flange and pipe.
Pipe Insertion: Insert the pipe into the flange socket. Align it to avoid bending or stress on the joint.
Welding: Use TIG or MIG welding to attach the pipe to the flange. A good quality weld is critical to avoid leaks.
Inspection: After welding, perform a visual inspection and non-destructive testing (such as ultrasonic or X-ray) to ensure the joint is leak-free.
Finish and Test: Clean the flange joint and apply any finishing coatings. Pressure test the system to ensure there are no leaks.

10. FAQ

Q1: What is the main advantage of a socket weld flange over other types of flanges?
A1: The socket weld flange provides a leak-proof connection due to the welding process. It is ideal for smaller bore pipes and systems under high pressure.

Q2: Can a socket weld flange be used for large diameter pipes?
A2: No, socket weld flanges are typically used for small diameter pipes (½” to 2”) and are not suitable for larger diameters where other flange types such as slip-on or weld neck flanges are preferred.

Q3: What materials are typically used for socket weld flanges?
A3: Carbon steel, stainless steel, and alloy steel are the most common materials used, but Duplex stainless steel and nickel alloys are also available for special applications.
