Abstract

Over the past few years, there have been several instances in the oil and gas industry of incompatibilities and failures of stainless steel components carrying or containing chemical products. Material of construction compatibility with chemical products is a vital assessment to ensure asset integrity of critical components is maintained during field operation. The focus of this paper is on the evaluation of neat chemical product compatibility with stainless steel 316L (SS316L, UNS S31603), a commonly used alloy for storage tanks and umbilical tubing. A typical approach to assess the compatibility of stainless steel with neat chemical products involves using a weight loss immersion corrosion test methodology. However, this procedure has the inherent limitation in that it can take a long time to conduct, while data interpretation can be difficult because the induction period for pitting is unknown. This paper presents and discusses data from accelerated stainless steel compatibility tests of various neat c...
