General Requirements4.1 Material furnished to this specification shall conform tothe applicable requirements of the current edition of Specifi-cation A999/A999M, unless otherwise provided herein.5. Materi

29、als and Manufacture5.1 Pipe may be either hot finished or cold drawn with thefinishing treatment as required in 5.3.5.2 Grade P2 and P12The steel shall be made by coarse-grain melting practice. Specific limits, if any, on grain size ordeoxidation practice shall be a matter of agreement betweenthe ma

30、nufacturer and purchaser.5.3 Heat Treatment:5.3.1 All pipe shall be reheated for heat treatment and heattreated in accordance with the requirements of Table 2.NOTE 3It is recommended that the temperature for tempering shouldbe at least 100 F 50 C above the intended service temperature;consequently,

31、the purchaser should advise the manufacturer if the servicetemperature is to be over 1100 F 600 C.NOTE 4Certain of the ferritic steels covered by this specification willharden if cooled rapidly from above their critical temperature. Some willair harden, that is, become hardened to an undesirable deg

32、ree when cooledin air from high temperatures. Therefore, operations involving heatingsuch steels above their critical temperatures, such as welding, flanging,and hot bending, should be followed by suitable heat treatment.6. Chemical Composition6.1 The steel shall conform to the requirements as toche

33、mical composition prescribed in Table 1.7. Workmanship, Finish, and Appearance7.1 The pipe manufacturer shall explore a sufficient numberof visual surface imperfections to provide reasonable assurancethat they have been properly evaluated with respect to depth.Exploration of all surface imperfection

34、s is not required but maybe necessary to ensure compliance with 7.27.2 Surface imperfections that penetrate more than 1212 %of the nominal wall thickness or encroach on the minimumwall thickness shall be considered defects. Pipe with suchdefects shall be given one of the following dispositions:7.2.1

35、 The defect may be removed by grinding provided thatthe remaining wall thickness is within specified limits.7.2.2 Repaired in accordance with the repair welding pro-visions of 7.6.7.2.3 The section of pipe containing the defect may be cutoff within the limits of requirements on length.7.2.4 Rejected

36、.7.3 To provide a workmanlike finish and basis for evaluat-ing conformance with 7.2, the pipe manufacturer shall removeby grinding the following:7.3.1 Mechanical marks, abrasions (see Note 5) and pits,any of which imperfections are deeper than116 in. 1.6 mm.NOTE 5Marks and abrasions are defined as c

37、able marks, dinges, guidemarks, roll marks, ball scratches, scores, die marks, and the like.7.3.2 Visual imperfections, commonly referred to as scabs,seams, laps, tears, or slivers, found by exploration in accor-dance with 7.1 to be deeper than 5 % of the nominal wallthickness.7.4 At the purchasers

38、discretion, pipe shall be subject torejection if surface imperfections acceptable under 7.2 are notscattered, but appear over a large area in excess of what isconsidered a workmanlike finish. Disposition of such pipe shallbe a matter of agreement between the manufacturer and thepurchaser.7.5 When im

39、perfections or defects are removed by grinding,a smooth curved surface shall be maintained, and the wallthickness shall not be decreased below that permitted by thisspecification. The outside diameter at the point of grinding maybe reduced by the amount so removed.7.5.1 Wall thickness measurements s

40、hall be made with amechanical caliper or with a properly calibrated nondestructivetesting device of appropriate accuracy. In case of dispute, themeasurement determined by use of the mechanical caliper shallgovern.7.6 Weld repair shall be permitted only subject to theapproval of the purchaser and in

41、accordance with SpecificationA999/A999M.7.6.1 All repair welds in P91 shall be made with one of thefollowing welding processes and consumables: SMAW, A5.5/A5.5M E90XX-B9; SAW, A5.23/A5.23M EB9 + neutral flux;6Available fromAmerican Society for Nondestructive Testing (ASNT), P.O.
