Socket Weld Tee
Socket Weld Tee Manufacturer & Supplier
A Socket Weld Tee is a pipe fitting that can combine or split fluid flow. It has a T-shaped form, with one inlet and two exits at 90-degree angles. These fittings are designed for small bore piping systems and are typically used in high-pressure applications.
