Proceedings of the Biennial International Pipeline Conference, IPC | Year: 2012

The paper describes the results of elaborated development work and the application of the very latest technology on steel, plate and pipe making, the recent demand on grade API-5L X70 or even API-5L X80 for specific sour service applications can be met. Furthermore the paper will point out the overall production concept which provides the fundament for the production of such steels with consistent and reliable resistance to hydrogen induced cracking (HIC). The essential parameters will be explained. This includes the utilization of an appropriate quality assurance system. Recent achievements in terms of strength level, thickness and sour service conditions will be explained. Copyright © 2012 by ASME.

The developments of plates are strongly driven by demands from highsophisticated pipeline and structural applications. Such needs reflect in plates with higher thickness, larger width, higher toughness also at lower temperatures, higher strength and/or better resistance to sour environments. The requirement profiles are, in some cases, exceptional and have become achievable, in an extreme combination of alloying and processing technologies, only as a result of comprehensive development work and plant investments. A broad potential for innovation derives by the utilization of the key-technology TMCP (Thermo-Mechanical Controlled Process). The status of present-day heavy plate production will be presented. An outline of the production facilities, routes and process variants will be given. As a central element to achieve high-class requirements, aspects and parameters of the metallurgical design will be explained. The utilization will be explained and illustrated with selected recent applications. © EDP Sciences, 2011.

Substantially financial benefits and environmentally friendly effects can be achieved when using highstrength fine-grained structural steels in an appropriate constructive design. In steel construction, fine-grained structural steels with yield strength up to 1300 MPa are presently available, that can be used with the traditional methods of steel construction for assessment, processing, operation, deconstruction and disposal. They open up new possibilities to manufacture extremely stress-resistant structures with a comparatively low weight. Steel structures with yield strength up to 700 MPa can be used on the basis of the current state of the art as described in the national technical approvals of Eurocode 3 (EN 1993-1 and EN 1090) through building control authorities. In addition to some typical examples of application, considerations for the application of extremely stress-resistant fine-grained structural steels and aspects of sustainability will be shown.
