Product introduction
High-Pressure 90° Socket Weld Elbow
A forged steel piping component designed to create precise right-angle turns in high-pressure systems (3000psi+) using socket weld connections for maximum joint integrity.
Technical Specifications
Critical Design Features
90° Short/Long Radius:
SR (1D) for compact installations
LR (1.5D) for reduced pressure drop
Reinforced Hub Design: 20% thicker wall than standard SCH160 elbows
Full Bore Construction: Maintains ID continuity to minimize flow restriction
Weld Prep Bevel: 37.5° chamfer for optimal weld penetration
Material Grades
Carbon Steel: ASTM A105N (Normalized)
Stainless Steel: ASTM A182 F316L (Low Carbon)
Alloy Steel: ASTM A182 F11/F22 (Chrome-Moly)
Corrosion-Resistant: Hastelloy C276/Nickel 625
