The purpose of this specification is to provide standards for the purchase of q
11、uenched-and-tempered steel plate suitable for use in welded offshore structures. Nothing in this specification should be interpreted as indicating a preference by the committee for any material or process. In the selection of materials and processes, the purchaser must be guided by his experience an
12、d by the service for which the plate is intended. Changes from the previous edition are noted by bars in the margins. Shall: As used in a standard, “shall” denotes a minimum requirement in order to conform to the specification. Should: As used in a standard, “should” denotes a recommendation or that
13、 which is advised but not required in order to conform to the specification. Suggested revisions are invited and should be submitted to the Director of the Standards, American Petroleum Institute, 1220 L Street, N.W., Washington, D.C. 20005. v TABLE OF CONTENTS 1 SCOPE1 1.1 Coverage.1 1.2 Post Manuf

17、ermo-Mechanical Control Processing (TMCP) 1 Scope 1.1 COVERAGE This specification covers two grades of high strength steel plates for use in welded construction of offshore structures, in selected critical portions which must resist impact, plastic fatigue loading, and lamellar tearing. Grade 50 is
18、covered in thicknesses up to 6 in. (150 mm) inclusive, and Grade 60 is covered in thicknesses up to 4 in. (100 mm) inclusive. 1.1.1 It is intended that steel produced to Grades 50 of the basic API Spec 2W, without Supplementary Requirements, although produced in a different manner and of somewhat di
19、fferent chemical compositions, be at least equivalent in minimum performance and, therefore, in service application, to the corresponding grades listed in Sections 5 through 7 of API Spec 2H. Higher performance (i.e., notch toughness at lower temperatures, or enhanced weldability) typically availabl
20、e with TMCP steel may be achieved by specification of Supplementary Requirements. 1.1.2 API Spec 2W steels are intended for fabrication primarily by cold forming and welding. The welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steels and the
21、ir intended service. Because of the characteristic high YS/TS ratio of TMCP steels, users may want to consider welding consumables which avoid under-matched weld metal. Conversely, the steels should be amendable to fabrication and welding under shipyard and offshore conditions. 1.2 POST MANUFACTURIN
22、G HEATING 1.2.1 Due to the inherent characteristics of the TMCP method, plates manufactured to this spec cannot be formed or postweld heat treated at temperatures above 1100F (595C) without some risk of sustaining irreversible and significant losses in strength and toughness. If warm-forming is to b
23、e required during subsequent fabrication, the tensile and notch toughness properties of the finished component shall be verified and the properties shall conform to the requirements of this specification. The procedure for verification shall be subject to mutual agreement. The plates may be post-wel
24、d heat treated at elevated temperatures not exceeding 1100F (595C) providing test coupons are subjected to a thermal cycle to stimulate such fabrication operations, as described in Supplementary Requirement S9. Verification or simulation is not necessary for heating at temperatures not exceeding 400
