Product Description
ASME B16.5 F310S Socket Weld Flange Overview
Socket Weld Flanges are engineered for small-diameter, high-pressure piping systems. The connection method involves inserting the pipe end into the flange socket and performing external corner welding, ensuring smooth internal transitions and minimal flow resistance. While easier to weld and align than butt welding, these flanges require careful consideration in highly corrosive environments due to potential gaps.

F310S High-Temperature Stainless Steel Properties
F310S is a high-chromium, medium-nickel austenitic stainless steel specifically engineered for extreme high-temperature conditions. It delivers exceptional oxidation resistance, maintaining structural stability at temperatures up to 1093°C (2000°F) without significant oxide scale formation. Compared to standard 304 or 316 stainless steels, F310S provides superior strength and creep resistance under thermal cycling conditions.

Flange Facing Types Explained
Raised Face (RF) flanges concentrate bolt preload force on smaller gasket contact areas for reliable sealing. The Class 150 flange utilizes this effective sealing surface. SMLSCO also provides Full Face (FF) for low-pressure applications and Ring Type Joint (RTJ) for ultra-high pressure conditions, meeting diverse project sealing requirements.
