YOUR SOURCE FOR SOCKET WELD FLANGES
Socket weld flanges for small-bore, high-pressure piping systems. The pipe inserts into a recessed socket and is fillet welded for a strong, leak-resistant connection.
We maintain one of the largest inventories of socket weld flanges in the Houston area. Every flange is manufactured to ASME, ANSI, and API standards with full material traceability and certification.

We supply flanges for data center cooling systems, fire suppression piping, and critical infrastructure. Hyperscale facilities require precision-manufactured flanges that meet demanding specifications for reliability and performance.
A socket weld flange has a recessed bore (socket) that the pipe inserts into. A fillet weld around the hub secures the joint. This design provides excellent strength for small-bore piping up to NPS 4.
Per ASME B16.11, a 1/16 inch (1.6mm) gap must be maintained between the pipe end and the bottom of the socket to allow for thermal expansion and prevent cracking during welding.
Socket weld flanges are standard in NPS 1/2 through NPS 4 per ASME B16.5. They are available in Class 150 through 2500, though Class 150 through 600 are most common.
