Construction code is ASME B31.3(Power Cycle Piping)
But as per my vendor, the selection of penetrometer is the total thickness including reinformcements of the welds.So, based on the thickness the weld reinforcment varies, so vendor argues that it can create confusion(only in border cases) if wall thickness is mentioned in the film.
Generally, the film identification shall be placed on the film to make a corelation with the report & to fullfill the mandatory requirements as laid down by the code.
Kindly advise.

Subject: [MW:13257] Identification of thickness on Radiography films.
Dear Experts,
During Interpreting Radiography films at one of my vendor's works, I observed that, there is no identification /indicate thickness of job on film so I rejected the film. As far as generally everyone related field experience persons are know unless identification of thickness on film it is very difficult to know which penetrameter to be used but my vendor is arguing for the same. According to him one of "Level III" person insisit them there is no need to mentioned thickness in Radiography films and it sufficient if it indicate in Radiography interpretion report.
Suppose in piping number of joints/piping spools are comming with verious thickness in same report in such case it is possible to identify required penetrameter ? My anser is no, each Radiography films must be indicat thickness of joint/job. Requested to suggest/advise.
Sincerely yours,
RK Vichare
