We provide a range of Audco Triple-offset Butterfly Valves in austenitic stainless steels suitable for cryogenic services as low as -196°C. The valves are offered with extended bonnets to ensure that cryogenic line fluids do not impair the performance of gland packings. The cryogenic range conforms to BS 6364 and is available in classes 150 to 600 in a variety of body styles and end-connections.
The properties of INCONEL alloy 725 are useful for a range of applications that require outstanding corrosion resistance along with high strength. The alloy is used for hangers, landing nipples, side pocket mandrels and polished bore receptacles in sour gas service, where it resists the effects of hydrogen sulfide, chlorides and carbon dioxide. The alloy is also attractive for high strength fasteners in marine applications, where it resists corrosion, pitting and crevice attack in sea water.
