What is a Threaded/Socket Weld Square Head Plug?

A Threaded/Socket Weld Square Head Plug is a forged pipe fitting designed to seal the end of a pipe or fitting. It features a distinctive square-shaped head for easy installation and removal using a wrench, making it ideal for maintenance or inspection points in piping systems.

Threaded Square Head Plug: Equipped with internal threads (typically NPT, BSP, etc.), this plug allows for quick, leak-tight closure without the need for welding—perfect for low-pressure systems and installations where future disassembly is required.
Socket Weld Square Head Plug: Designed with a socket for precise pipe insertion and strong weld joints, offering a permanent and pressure-resistant seal suitable for high-pressure or high-temperature systems.

These plugs are essential for closing off open pipe ends, protecting system integrity, and ensuring safety during maintenance or system shutdowns.
