A 45 degree socket weld elbow is a forged pipe fitting used to change the direction of fluid flow by 45 degrees in small diameter, high pressure piping systems.
Socket weld elbows are typically specified where leak resistance, weld strength, and joint integrity are critical.
The pipe is inserted into the socket and fillet welded, providing a strong and compact connection suitable for Class 3000, 6000, and 9000 pressure ratings.
Stainless steel socket weld elbows are widely used in corrosive and high-pressure service environments where long-term reliability is required.
• 45 Degree Socket Weld Elbow – Used to change flow direction with reduced pressure drop compared to 90° elbows
This fitting is designed in accordance with ASME B16.11 and compatible with global forged fitting specifications.
