ANSI B16.5 3 Inch Stainless Steel SPECIAL FLANGE

Long Weld Neck Flange Information

A "Stainless Steel Special Flange" typically refers to a flange that has unique or custom features tailored to specific requirements beyond standard flange designs. These special flanges are often designed to meet particular needs in industrial applications where standard flanges may not suffice.

Special flanges are designed to meet specific requirements that standard flanges cannot accommodate. This customization can include non-standard dimensions, unique facing types, special materials, or specific pressure ratings tailored to the application.

Stainless Steel Special Flanges are made from stainless steel, offering excellent corrosion resistance and durability. The choice of stainless steel ensures that the flange can withstand harsh environments and applications where corrosion is a concern.
