A metal sockolet is a type of pipe fitting used in piping systems to provide a branch outlet. It’s similar to a weldolet but has a socket-like end instead of a weld connection. This socket end allows for easy attachment to the main pipe through welding or threading, providing a smaller secondary pipe connection. Metal sockolets are commonly made from materials like stainless steel, carbon steel, or alloy steel, depending on the requirements of the application. They’re often used in industries such as oil and gas, petrochemical, and power generation for branching off pipelines to accommodate additional connections.
