- 77.140.10 Heat-treatable steels
This document specifies requirements for weldable structural steels made of hot finished seamless and high frequency welded hollow sections to be used in the fabrication of fixed offshore structures.
The following thickness limitations are given in this standard:
for seamless hollow sections up to and including 65Ã‚Â mm;
for HFW hollow sections up to and including 25,4Ã‚Â mm.
Greater thicknesses can be agreed, provided the technical requirements of this European Standard are maintained.
This European Standard is applicable to steels for offshore structures, designed to operate in the offshore sector but not to steels supplied for the fabrication of subsea pipelines, risers, process equipment, process piping and other utilities. It is primarily applicable to the North Sea Sector, but may also be applicable in other areas provided that due consideration is given to local conditions e.g. design temperature.
This document has an informative AnnexÃ‚Â E on the prequalification of steels for fixed offshore structures in arctic areas.
Minimum yield strengths up to 770Ã‚Â MPa are specified together with impact properties at temperatures down to Ã¢â‚¬â€œ40Ã‚Â Ã‚Â°C.
