Applications & Selection Guide

Stainless steel weld-neck flanges in AISI 304 to EN 1092-1 Type 11 — tapered hub butt-welded to the pipe, matching bore, and raised gasket face for maximum joint integrity in stainless systems.

Weld-necks are used on stainless process lines, steam and hot-water service, and cyclic or vibrating duty where the hub's smooth stress transfer prevents fatigue at the flange weld. State the pipe wall at order so the hub bore matches. Select the PN class and DN from the table above; for chloride environments consider 316L equivalents.

Quoted and sold per piece. Include PN, DN, pipe wall, quantity, and delivery country in your quote request for exact pricing and lead time.
