Sockolets
Sockolets are branch connection fittings that use a socket-weld design, allowing a plain-end branch pipe to be inserted and fillet welded to the run pipe for secure attachment.
Ideal for small-diameter, high-pressure piping systems, Sockolets are widely used in oil and gas, petrochemical, and power generation industries for reliable branch connections.
Sockolets feature a socket-weld connection where a plain-end branch pipe is inserted into the socket and secured with a fillet weld, while the fitting itself is fillet welded to the run pipe. Unlike Weldolets, which use a butt-weld with beveled ends, Sockolets are designed for smaller pipe sizes and offer ease of installation in high-pressure systems. Their reinforced design minimizes stress concentrations, ensuring strong and durable branch connections suitable for demanding industrial applications.
Sockolets are manufactured to meet stringent industry standards, ensuring compatibility and performance in demanding piping systems.
