Steel Coupling

Product Details:

Stainless Steel 304 Socket Weld Coupling 1. Product Description

A Socket Weld Coupling is a type of pipe fitting used to connect two pipes or a pipe to a fitting by inserting the pipe into a recessed socket end and then welding around the joint. The coupling provides a strong, leak-proof joint, typically used in high-pressure systems.

2. Material 3. Design Features 4. Sizes

• Common Sizes: 1/8” to 4” (or larger per availability)

• Dimensions per ASME B16.11

5. Applications

• Chemical and petrochemical plants

• Power generation systems

• Oil and gas industries

• Food and pharmaceutical industries

• High-pressure fluid transport lines

6. Advantages

• Strong, permanent joints with good strength

• Suitable for high-pressure and high-temperature applications

• Less prone to leakage compared to threaded fittings

• Compact design suitable for tight spaces

• Corrosion resistant due to SS 304 material
