30、the tolerances in Table 5 except asnoted in 10.2.2.10.2.2 These outside diameter tolerances shall not apply tothe “as-welded” pipe when measured across that portion whichcontains the weld zone.10.3 Wall Thickness Tolerances:10.3.1 The wall thickness of pipe furnished in drawntempers or as fully fini
31、shed shall conform to the tolerancesshown in Table 6, except as noted in 10.3.2 and 10.3.3.10.3.2 The tolerances of Table 6 shall not apply to thatportion of the “as-welded” wall which contains the weld flashor bead.10.3.3 The tolerances of Table 6 shall be increased by100 % for that portion of the
32、“as-welded” wall which containsthe weld zone.10.4 Lengths and Tolerances:10.4.1 Pipe in straight lengths shall be furnished in stocklengths with ends included unless the order requires specificlengths or specific lengths with ends.10.4.2 The tolerances for pipe furnished in straight lengthsshall be
33、as shown in Table 7.10.4.3 The schedule for pipe furnished with specific or stocklengths with ends shall be in accordance with Table 8.10.5 Squareness of CutThe departure from squareness ofthe end of any pipe shall not exceed 0.016 in./in. (0.016mm/mm) of diameter.10.6 RoundnessThe difference betwee
34、n the major andminor diameter of pipe as determined at any one cross sectionshall not exceed 3 % of the nominal outside diameter.11. Workmanship, Finish, and Appearance11.1 The pipe shall be free of defects of a nature thatinterferes with normal commercial applications. It shall be wellcleaned and f

Drillings,milling, and so forth, shall be taken in approximately equalweight from each of the s
37、ample pieces selected in accordancewith 12.1.2 and combined into one composite sample. Theminimum weight of composite sample for chemical analysisshall be 150 g divided into three equal parts.12.2.1 Instead of sampling in accordance with PracticeE 255, the manufacturer shall have the option of deter
38、miningconformance to chemical composition as follows: Conform-ance shall be determined by the manufacturer by analyzingsamples taken at the time the castings are poured or samplestaken from the semifinished product. If the manufacturerdetermines the chemical composition of the material during thecou
39、rse of manufacture, he shall not be required to sample andanalyze the finished product. The number of samples taken fordetermination of chemical composition shall be as follows:12.2.1.1 When samples are taken at the time the castings arepoured, at least one sample shall be taken for each group ofcas
40、tings poured simultaneously from the same source ofmolten metal.12.2.1.2 When samples are taken from the semifinishedproduct, a sample shall be taken to represent each 10 000 lb(4550 kg) or fraction thereof, except that not more than onesample shall be required per piece.12.2.1.3 Due to the disconti
41、nuous nature of the processingof castings into wrought products, it is not practical to identifyspecific castings analysis with a specific quantity of finishedmaterial.12.2.1.4 In the event that heat indentification or traceabilityis required, the purchaser shall specify the details desired.12.3 Ten
42、sion TestsFor the tension tests a specimen shallbe taken from each of the pieces selected in accordance with12.1. The required tension tests shall be made on each of thespecimens so selected.13. Retests13.1 If any test specimen shows defective machining ordevelops flaws, it may be discarded and anot

44、of any test made to determine themechanical properties fail to meet the specified limits, this testshall be repeated on each of two additional specimens takenTABLE 5 Average Outside DiameterATolerancesSpecified Diameter, in.
