This part of EN 10225 specifies requirements for submerged arc welded (SAW) and high frequency welded (HFW) cold formed hollow sections to be used in the fabrication of fixed offshore structures. The thickness limit for SAWL round hollow sections is up to and including 50,8 mm, for HFW round hollow sections up to and including 25,4 mm and for HFW rectangular hollow sections up to and including 12,5 mm. Greater thicknesses for SAWL hollow sections may be agreed provided the technical requirements of this European Standard are maintained. NOTE 1 There is an Annex E about SAWH round hollow sections with thickness limit of 30,0 mm and an Annex F about high strength rectangular HFW hollow sections steel grades S550 to S700 for further information please refer to it. The 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. temperature. NOTE 2 There is an Annex G on the prequalification of steels for fixed offshore structures in arctic areas. Minimum yield strengths up to 690 MPa are specified together with low temperature impact properties at temperatures down to -40 °C.
