PIPE OR FITTING DISCONTINUITIES Arc burns, long seam discontinuities and other discontinuities in the pipe or fittings detected by radiographic testing shall be reported to the company. (Individual) = 1/2” (12.7mm) (Aggregate length in any continuous 12” (12.7mm) exceeds 2” (50.8mm) Individual indications of HB each greater than 1/4” (6.35mm) in length are separated by less than 2” (50.8mm)Īggregate length of indications in any combination in any 12” of weld exceeds 2” (50.8mm)ĮXCESSIVE PENETRATION Any individual instance of excessive root bead deposition shall not exceed 4mm and not longer than 20mm Any excessive root bead deposits shall be separated by at least 150mm of sound weld metalĮxcluding Incomplete Penetration due to high low and undercutting Aggregate length of indications in any continuous 12” of weld exceeds 2” (50.8mm) The diameter of the cluster exceeds 1/2” (12.7mm) The aggregate length of Cluster Porosity in any continuous 12” of weld exceeds 1/2” (12.7mm) An individual pore within a cluster exceeds 1/16” (1.59mm) Cluster porosity that occurs in the finish pass shall be unacceptable when any of the following conditions occur. (Individual) = 1/8” (3.17mm) The distribution of scattered porosity exceeds the concentration permitted by figure 18 or 19Ĭluster porosity that occurs in any pass except the finish pass shall comply
If more than four ISI indications with the maximum width of 1/8” (3.17mm) are present in any continuous 12” of weld then the weld is rejectable. Parallel ESI indications separated by approximately the width of the root bead (Wagon tracks) shall be considered a single indication unless the width of either of them exceeds 1/32” (0.79mm) In that event they shall be considered separate indications. I dont see an option to access Volume Profile using any API at the moment.
