Product Description
Product Overview
The ASME B16.5 F310S Socket Weld Flange Class 150 RF is engineered for small-diameter, high-pressure piping systems, delivering exceptional performance in demanding industrial environments.
Socket Weld Flange Design
Socket Weld Flanges feature a specialized connection method where the pipe end inserts into the flange socket and is welded externally. This innovative design provides:
- Smooth internal pipeline transition with minimal flow resistance
- Simplified welding and alignment compared to butt welding
- Optimal performance for small-bore, high-pressure systems
Note: Requires careful consideration for highly corrosive media due to potential gap between pipe and socket
