Sandvik Sets New Industry Standards with Next Generation CRAs

Sandvik is setting new industry standards with its next generation of high performance materials to meet the operational demands brought about by extreme water depths below 10,000 feet (3,000 meters) and temperature above 400 degrees Fahrenheit (204 degrees Celsius). These advanced corrosion resistant alloys (CRAs) offer increased reliability and enhanced corrosion resistance in the harshest conditions while reducing environmental impact.

“Introduction of these high performance materials really is a leap in technology similar to that seen following the development and introduction of the first duplex stainless steel,” said Nigel Haworth, Manager Sandvik Business Unit Oil & Gas.

“Whether we are talking topside hydraulic and instrumentation tubing, downhole production casing and tubing or highly versatile control and chemical injection lines, our corrosion resistant alloys are purpose designed to offer safe, reliable and cost effective solutions in the most demanding environments on the planet.”

Such high performance materials enable the production of seamless tube with higher yield strengths providing the capability to produce thinner wall umbilicals, which in turn reduces weight and reel sizes, helping to lower installation costs in deep sea applications.

‘Come Together’ is the Sandvik theme at OTC 2014 in Houston, Texas, bringing together partnerships with its customer to provide industry leading corrosion resistant material solutions.

Examples on display will include seamless tube products manufactured in high-alloy materials, as well as bar and hollow bar, complex components in powder metallurgically-based hot isostatic pressing (HIP) such as manifolds, swivels and wye-pieces, Sandvik ClikLoc rapid action connector for riser applications, wirelines and welding consumables.

“When it comes to corrosion resistance, material quality and cleanliness we set a higher standard within the standard with all material batches fully traceable through every stage of production right back to the original melt,” added Nigel Haworth.

 “Whether the installation is topside, subsea or downhole, understanding the environmental conditions in which the material has to operate successfully is vital.

"Working closely together with our customers we can achieve the optimum corrosion resistant alloy material solution for any given installation.”
