We are manufacturers of Alloy 20 Lap Joint Flanges that exhibit an ameliorated general corrosion resistance to sulphuric acids, much needed in the synthetic rubber manufacturing plants and mixing tanks. Supplied with pressure fittings (NPT), ASTM B462 Alloy UNS N08020 Blind Flanges that can be connected to a pipe or valve, equipment with a nozzle and their insusceptibility to acidic attack is a popular reason for them being in the offshore and oil industry. We are suppliers of Alloy DIN 2.4660 Weld Neck Flanges, a niobium added flange that decreases carbide precipitation during welding at elevated temperatures, thus being vital in the field of pickling equipment and process piping.
