本文件规定了用于制造固定式海洋结构物的可焊接结构钢（板状）的要求。 本标准给出了以下厚度限制: -S355NLO小于等于200mm； -S355MLO、S420MLO、S460MLO、S500MLO最大120毫米（含120毫米）； -S420QLO、S460QLO、S500QLO、S550QLO、S620QLO、S690QLO，小于等于150毫米。 如果符合本欧洲标准的技术要求，可以约定更大的厚度 保持。 本欧洲标准适用于设计用于海上作业的海上结构用钢，包括结构空心型材用钢板（见EN 10225-4）。它不适用于为制造海底管道、立管、工艺设备、工艺管道和其他公用设施而提供的板材。它主要适用于北海地区，但也可能适用于其他地区，前提是适当考虑当地条件。 g、 设计温度。 注:本文件的附录F提供了关于海上固定平台用钢材资格预审的信息 北极地区的结构。 规定了最高690 MPa的最小屈服强度以及温度下的冲击性能 低至-40°C。交叉引用:EN 10163-1EN 10079ISO 4063ISO 9712EN ISO 2566-1EN ISO 14284EN ISO 377EN 10027-1EN 10029EN 1011-1ISO 148-1ISO 3452-1ISO 6892-1ISO 14284EN ISO 4136EN ISO 6892-1EN ISO 15614-1EN 10168ISO 9934-1ISO 377EN ISO 6947ISO 643ISO 4885EN 10027- 2.2 ISO ISO 452-2 2-1 ISO 2-2-2 2-2-2-2-2-2 2 2 ISO 2 2-2 2 2 ISO 2 2 2 ISO 2 2 2 ISO 2 2 2 2 ISO 2 2 2 2 2 ISO 2 2 2 2 2-2 2 2 2 ISO 2 2 2 2 2-2 2 2 ISO 2 2 2 2-2 2 2 2 2 2 2-2 2 2 2 2 2-2 2 2 2-2 2 2 2 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12购买时的2EN包含在购买中这是本文件的一部分。

This document specifies requirements for weldable structural steels, in the form of plates, to be used in the fabrication of fixed offshore structures. The following thickness limitations are given in this standard: — S355NLO up to and including 200 mm; — S355MLO, S420MLO, S460MLO, S500MLO up to and including 120 mm; — S420QLO, S460QLO, S500QLO, S550QLO, S620QLO, S690QLO up to and including 150 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, including plate for structural hollow sections (see EN 10225-4). It does not apply to plates 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. NOTE This document has an informative Annex F on the prequalification of steels for fixed offshore structures in arctic areas. Minimum yield strengths up to 690 MPa are specified together with impact properties at temperatures down to -40 °C.Cross References:EN 10163-1EN 10079ISO 4063ISO 9712EN ISO 2566-1EN ISO 14284EN ISO 377EN 10027-1EN 10029EN 1011-1ISO 148-1ISO 3452-1ISO 6892-1ISO 14284EN ISO 4136EN ISO 6892-1EN ISO 15614-1EN 10168ISO 9934-1ISO 377EN ISO 6947ISO 643ISO 4885EN 10027-2EN ISO 3452-1ISO 15653ISO 12135ISO 15614-1ISO 6947EN 10051ISO 2566-1ISO 4136EN ISO 9934-1EN ISO 4885EN ISO 9712EN ISO 4063EN 10163-2EN 10020ISO 6507-1EN ISO 6507-1EN 10164EN 10160EN 10021EN ISO 643ISO 11484CEN/TR 10261EN ISO 148-1EN 10204EN 1011-2:2001EN 10025-6EN 10025-2EN 10025-3CEN/TR 10347EN 10025-4EN 10025-1All current amendments available at time of purchase are included with the purchase of this document.
