Applications & Selection Guide
Stainless steel flat (plate) flanges in AISI 304 to EN 1092-1 Type 01, machined with a flat gasket face and standard bolt circle for welded stainless connections.
Flat flanges connect stainless piping to tanks, pumps, and equipment in water treatment, food processing, and general industry at PN10–PN16 ratings. They are the economical choice where pressures are moderate and the joint is not highly cyclic; specify weld-neck for critical or high-pressure service. PN/DN combinations are listed in the table above.
Quoted and sold per piece. Send PN, DN, quantity, and destination in a quote request; gaskets and bolt sets in matching stainless grades can be quoted together.
