Nibron Special®

Extra high strength cupronickel

Oliver Valvetek produces an extensive range of needle and ball valves used in hostile subsea environments around the world. The high strength and corrosion resistance offered by Nibron Special®, available only from Columbia Metals, has made this alloy the perfect choice for gate valve override stems designed and manufactured by the company.

“We have a longstanding historical relationship with Columbia Metals and specify Nibron Special® for use in actuator stems,” says Paul Shillito, Engineering Director at Oliver Valvetek. “We use Nibron® ourselves and specify it on the technical drawings we send to our subcontractors. The valves are ultimately used in deepwater environments where corrosion resistance is of paramount importance, so Nibron® is the perfect alloy.”

Oliver Valvetek is committed to the highest standards of safety and innovation, a focus that has propelled the company forward in the global oil and gas industry. “The high strength of Nibron® gives us the confidence that we can rely on the alloy,” continues Paul. “We have also been particularly impressed by its resistance to marine growth and anti-galling properties.”
