[MW:6842] PQR according to ASME section IX

Dear All,

I'm preparing some WPS documents for procedure qualifications and
production documentation according to ASME section IX. In my opinion a
procedure qualification made in plate is also valid for pipes
according to ASME section IX as long as the essential variables are in
range of the specification, but can anyone tell me the paragraph where
this is mentioned in the rules? Welding process is PAW but this in my
opinion is also not an essential variable for diameter qualification.

Thanks in advance.

Herman Pieper
