Can you explain the difference between socket and socket weld fittings?

Difference Between Socket and Socket Weld Fittings

In the piping industry, socket and socket weld fittings are commonly used for connecting pipes or components. While both types of fittings serve a similar purpose, they have key differences that distinguish them.

Socket Fittings:

• Socket fittings are designed to be glued or cemented onto the pipe rather than welded.
• They are easier to install and do not require special welding equipment.
• Socket fittings are suitable for smaller pipe sizes and low-pressure applications.

Socket Weld Fittings:

• Socket weld fittings are welded to the pipe by inserting the pipe into the socket and then fillet-welding it.
• They provide a strong and leak-proof connection, making them ideal for high-pressure and high-temperature applications.
• Socket weld fittings are better suited for larger pipe sizes and critical systems where leakage is not acceptable.

In summary, socket fittings are non-welded connections that are easier to install and suitable for low-pressure applications, while socket weld fittings involve welding for a secure and reliable connection, making them a better choice for high-pressure systems.
