Hastelloy C22 Lap Joint Flanges

Hastelloy C22 Lap Joint Flanges are highly specialized pipe fittings that utilize a two-component assembly: a stub end and a loose-fitting back-up flange. The stub end, which is the wetted part, is welded to the pipe, and the loose flange slides over it. This unique design provides exceptional ease of alignment, as the bolt holes on the flange can be rotated to match the corresponding holes, making installation and frequent dismantling for inspection or maintenance much simpler. By using the highly corrosion-resistant Hastelloy C22 material for the stub end, these flanges are ideal for chemical processes where piping is lined or frequently accessed. Zeron Fasteners is a trusted manufacturer and supplier of robust and precise nickel alloy Lap Joint Flanges.
