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.”
