Corrosion resistant alloy
Published: 22 May, 2015
Exposed to a demanding tropical marine atmosphere at the NASA Research Center, Florida, USA, super-duplex SANDVIK SAF 2507 hydraulic & instrumentation tubing has reportedly remained corrosion free after an extensive one year trial.
Typically, hydraulic & instrumentation tubing used in the oil & gas industry are either offshore or shoreline installations subjected to high levels of salt, humidity, UV light and temperature. This is particularly the case in tropical marine installations where seawater evaporates leaving a higher concentration of chlorides on the tubing.
The study saw stainless steel seamless tube samples in 316L, 904L and 2507 positioned 150 feet from the mean high water mark on the east coast of Florida directly facing the Atlantic Ocean for a period of one year.

For a refinery in Germany unscheduled shutdowns were reportedly eliminated following the installation of a new tube bundle in a heat exchanger using hyper-duplex SANDVIK SAF 2707 HD seamless tubes.
Professor Olle Wijk, former head of research and development at SANDVIK, has been awarded the Jernkontoret’s grand gold medal in recognition of his life’s work devoted to the development of steel and the Swedish steel research network. “I was extremely touched by receiving this award and feel proud and humble at the prospect of this distinction – it means a lot to me,” said Professor Olle Wijk.
