High Quality SMO 254 Flanges Worldwide

Renaissance Fittings and Piping Inc. offers a wide array of 254 SMO Flanges, which is used in varied industrial and commercial sectors and is quality assured. SMO 254 Slip On Flanges (UNS S31254) is often used in Flue gas desulfurization scrubbers, Components used in petroleum production, Food processing equipment and more. In some applications, SMO 254 Spectacle Blind Flanges has been found to be a more cost effective substitute for high nickel and titanium alloys. SMO 254 Weld Neck Flanges is compatible with the common austenitic stainless steels. SMO 254 Lap Joint Flanges is developed for use in halide – containing environment such as seawater, hydrochloric acid and contaminated sulphuric acid. Meanwhile, these SMO 254 Socket Weld Flanges are also being offered in different sizes and shapes to our customers. The chemical composition of SMO 254 Threaded Flanges typically has a slightly higher copper content than the AL-6XN alloy. The original patent on SMO 254 Ring Joint Type Flanges was based, to some extent, on data that demonstrated that 0.5 % – 1 % copper in stainless steel produced an optimal combination of resistance to reducing acids and resistance to chlorides. SMO 254 Spacer Flanges contains copper only as a residual element, as do most austenitic stainless steels. The physical properties of SMO 254 Long Weld Neck Flanges are essentially equivalent as described herein. However, any differences in drop – evaporation tests for SMO 254 Nippo Flanges are not believed to be statistically significant.
