the Houston Chapters of NACE and ASM
January 14, 2014 at the HESS Building.
7:30 Technical Talk on ISOTROPIC QUALITY STEEL FOR OIL AND GAS APPLICATIONS
Speaker: Patrik Ölund of Ovako Steel, Stockholm, Sweden
Location: HESS, 5430 Westheimer Rd. Houston , TX 77056
ISOTROPIC QUALITY STEEL FOR OIL AND GAS APPLICATIONS
Oil and gas exploration and production provide many challenges to design of products used and the materials applied. The class of engineering steels is particularly suited to be used for conditions of high fatigue, wear, toughness and strength requirements. Experience in other challenging industries, such as Mining, Bearings and Heavy Vehicles, has shown that a high level of cleanliness, particularly with respect to sulfides and undeformable oxides and calcium aluminates, and repeatability of the steel chemistry are essential for optimized toughness and fatigue performance.
The presentation will i) cover theoretical considerations and results of the developed steel making process for isotropic quality steel, ii) discuss the steel quantification methods used for the process development and quality assurance, iii) show fatigue and impact testing of material in both longitudinal and transverse direction, iv) discuss and demonstrate the influence of stressed volume on the fatigue life of a component and v) discuss the influence of degree of reduction on the fatigue life of a component. The corrosion properties of steel made by these improved processes will also be presented.
Patrik Ölund is head of group research and development at Ovako. Educated at The Royal Institute of Technology (KTH), Stockholm, Sweden (1985–1990), he worked at the Swedish Institute for Metals Research (1990–1995) doing research relating to inclusions, fatigue and heat treatment. In 1995 he joined Ovako in the research department, which he now heads. Most recently, Ölund was 2013 winner of the Kami Prize, presented to a distinguished scientist whose research has become the basis of a technical development within the Swedish steel and metal industry.
