Piping and Valves. Material failure mainly because of corrosion is a highly dangerous and expensive phenomenon in the offshore sector of the oil and gas industry, associated with severe negative consequences such as loss of asset, loss of production due to plant shutdown, loss of human life, and health, safety, and environment HSE problems e. Additionally, piping systems are produced in large numbers for the topside facilities in the oil and gas plants. Thus, the main aim of this paper is to introduce a novel approach for the piping material selection in the offshore industry to minimize the risk of piping corrosion and weight reduction with an optimum cost. The central focus of the study is to develop a material selection tool based on a systematic material selection approach and the existing literature, standards, and specifications.

It replaces the edition. This standard should be seen in conjunction with other NORSOK standards for design, construction and installation of piping and systems. This fourth edition has, to a large extent, been simplified compared to previous edition. Projects shall develop pipe class sheets and valve data sheets to suit actual conditions, based on guidelines and requirements in this standard. The main focus is to establish simple, robust and cost efficient solutions. Material master sheets are included in Annex B and element datasheets ar found in Annex C.
