Corrosion resistant alloy

Published:  11 June, 2015

sandvik.jpgExposed 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.
