ASTM A182 254 SMO Valves
Arrow Piping Solutions is a leading manufacturer and exporter of ASTM A182 254 SMO Valves in India. These valves are crafted using 254 SMO, an austenitic stainless steel grade with outstanding performance in marine environments, cryogenic conditions, and high-temperature applications. Our SMO 254 Valves are engineered to handle extreme conditions and offer exceptional corrosion resistance, mechanical strength, and pressure ratings.
The austenitic microstructure of 254 SMO ensures high impact strength at both room and cryogenic temperatures (as low as -196°C). Our UNS S31254 SMO 254 Cryogenic Globe Valves are ideal for extremely low-temperature use. Additionally, with high nickel content and proper heat treatment, our SMO 254 Ball Valves perform efficiently in high-temperature applications like ballast water systems, heat exchangers, firefighting systems, and cooling systems in marine settings.
All valves are manufactured using hot forged bar stock, then heat-treated per ASTM specifications. Every SMO 254 Valve from Arrow Piping Solutions undergoes strict quality control, including leak testing, pressure testing, and compliance with ANSI/ASME/API/MSS standards.
