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

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.
