Sockolet Socket Weld Branch Outlet
Our Sockolet is hot forged branch connection fitting with socket weld end, designed for high-pressure pipeline branch tapping without cutting main pipe. Strictly manufactured to MSS SP-97 & ASME B16.11 standards, all sizes keep full nominal dimension without minus tolerance, widely used for power, chemical, oil & gas instrument piping.
Overview
Sockolet (Socket Weld ) is a forged reinforcing branch outlet fitting, also known as socket weld branch saddle. Instead of traditional tee cutting, it is welded directly onto the main pipe to create reinforced branch connection, offering higher pressure resistance and structural strength than standard tees.
Integrally hot forged from carbon steel A105 or stainless steel A182 F304/F316L, uniform thick wall for heavy load service. We control all dimensions strictly, guarantee zero minus tolerance on wall thickness and outer diameter, no thin-wall cutting corners. Three standard pressure classes (3000LB / 6000LB / 9000LB) meet various high-pressure industrial working conditions.
Core Key Features
- One-piece hot forging forming, reinforced saddle structure, superior load & pressure bearing capacity
