Product Description
Product Overview
20" WN-SG A105N CL.300 SCH.40 B16.5 Carbon Steel Weld Neck Small Groove Flange designed for high-pressure industrial applications.
Key Specifications
Parameter Value
Size Range 20"
Pressure Class Class 300
Standards ASTM A105N
Face Type WN-SG Weld Neck Small Groove
Specification ANSI B16.5
Coating Options Anti-rust Paint, Cold and Hot Dip Galvanized, Zinc Plated, Yellow Transparent, Oil Black Paint
Face Type: Small Groove
Small Groove Flanges are self-aligning components that create efficient channels for fluid and gas transport in industrial systems. These flanges do not contact the transported media and can be attached to pipes without welding processes.
Flange Type: Weld Neck (WN)
Weld neck flanges feature a tapered hub design that effectively redistributes stress to connected pipes, reducing high-stress concentration at the flange base. Manufactured through forging processes, these flanges are welded directly to pipes for secure, permanent connections.
Material Specifications: ASTM A105/A105N
ASTM A105 flanges are forged carbon steel components designed for ambient and elevated temperature service in pressure systems. A105N designation indicates normalization heat treatment, providing enhanced mechanical properties for critical applications.
