SMO 254 Pipe Fittings
Arrow Piping Solutions is a trusted manufacturer, supplier, and exporter of a broad range of SMO 254 Buttweld Pipe Fittings in India. Our range includes ASME SA403 SMO 254 45° Elbow, 254 SMO® 90° Elbow, SMO 254 Reducers, UNS S31254 Pipe Elbows, SMO 254 Pipe Caps, ANSI B16.9 SMO 254 Reducers, and more.
We supply SMO 254 Pipe Fittings such as seamless and welded elbows, tees, crosses, reducers, and pipe caps that are engineered to resist corrosion, acids, and pitting. SMO 254 is an austenitic stainless steel known for its superior strength and corrosion resistance. Due to its high work hardening rate, it is relatively challenging to machine or weld but offers exceptional durability in aggressive environments.
At Arrow Piping Solutions, we employ modern manufacturing technology and precise testing methods to produce pipe fittings that meet global quality standards. Our fittings are widely used in various applications including saltwater handling systems, pulp bleaching plants, food processing units, chemical industries, and heat exchangers.
