RE: [MW:24130] what is the difference between QAP and ITP

Hi,

 

ITP – Inspection test plan includes tests, its acceptance tolerance, type of instruments used, its accuracy etc –

Ex –

Pipe thickness – ultrasonic method, XXX instrument, nominal thickness 10mm, acceptable "-0mm +1.6mm" etc, frequency each pipe measured from outside, at 6 locations, procedure for testing – as per Doc # - XXXXX

ITP is a in house document of a manufacturer. (in some complicated cases, and close tolerance requirement cases clients asks for ITP also)

In ITP manufacturing process also defines, but where as in QAP it is not required.

 

Whereas QAP means it's a quality plan and broad details will be their…

Ex- Pipe,

Thickness, Dia, Length

Frequency – each pipe

Acceptance norms – Client spec / ASTM code / Project spec / approved drawing etc

Client witness / TPI witness etc

QAp is a client approval document.

 

 

 

Thanks & Regards,

ITP is given by customer which covers only main inspection calls e.g. full component after welding UT of only some joints, final machining dimensions and after assembly inpection whereas QAP is made by the manufacturer which covers all the stage wise inspection..
