    ASME IX requirement for WPS PWHT Temperature range Vs PQR PWHT Temperature

    Hello, I have one question related to a WPS for A351 CF8M (basically a cast 316SS version). The PQR was performed with a PWHT (solution annealing and water quenching) to 1075°C (1967°F), with impact test. Given that QW 407.2 refers to QW 407.1, and the P no. of the base metal being 8, the...

    "M" activity on ITP

    Thank you guys.... @ Andre this is the answer which is close to my personal experience. The question now is: is there some "official" references (i.e. a standard) to this definition? Marco

    Is there a standard for Material Test Reports

    Dear Mumawalde, I suggest you to take a look at EN10204 - Metallic products - Types of inspection documents. Should you need a 3.1 certificate, the doc must reflect property of the material you are purchasing, therefore if reference ASTM indicates chemical analysis and mechanical properties, a...

    "M" activity on ITP

    Dear All, hope the question is not too basic. I have in front of me an inspection and test plan (ITP), on which customer has placed, in his column, a series of H,W,R (to which I am quite used to), and a "M". I know it stands for "Monitoring", but it's not clear to me how I should handle it...

    Attilio, you should go through the FAQs which you find on the official site: http://www.standard.no/en/Sectors/Petroleum/NORSOK-Standard-Categories/M-Material/M-6503/ I guess the answers given there are very clear. Ciao Marco

    Impact test: Energy Vs Lateral Expansion

    Again, I fully agree. Values are 101-106-99 J on HAZ and 90-89-92 on WM, therefore it's more than reasonable to assume lateral expansion values much higher than 0.38 mm (1.00 mm according my experience as well). I will talk to the lab, or try to convince customer. Will let you know how it...

    Impact test: Energy Vs Lateral Expansion

    Thank you Metaljon, I am testing a cast alloy 6Mo (ASTM A351 CK3MCuN). I fully agree with you, the problem is that the submitted WPS/PQR was originarily issued 3 years ago, and I am no more in possess of impact test specimens to be measured. So, I see just 2 solutions: 1) trying to convince...

    Impact test: Energy Vs Lateral Expansion

    Dear All, I have lately submitted (for a new Project) a previously qualified WPS+PQR (according to ASME IX). At PQR stage I carried out a certain no. of impact tests, reporting the results as energy absorbed [J]. Now, my accurate customer is rejecting the PQRs because project specification...

    Preheat and Preheat Maintenance

    Eddy, sounds clear to me. I will note the minimum temperature on the PQR; isn't it mandatory to list the same minimum temperature on the supported WPS? Jbeckhou, I don't have a min/max value. The aim of the operation is just to eliminate moisture on the weld just before starting the welding...

    Preheat and Preheat Maintenance

    Dear All, I have one question. Our welder is carrying out a qualification of a new WPS, by welding a cast coupon in duplex 2205 with duplex 2209. The welding activities shall be distributed during 5 days. To reduce to minimum the presence of humidity on the weld, the welder shall lightly...

    Impact values on Hastelloy C276 cast steel CW12MW

    Dear All, we have produced one sand cast body acc. ASTM A494 CW12MW (corrispondent of Hastelloy C276); it's a pressure containing part, therefore customer requested us to carry out an impact test at T=room (not requested by ASTM A494), guaranteeing 27J minimum. Now, we have carried out the...

    Furnace uniformity survey - API 6A

    Dear all, I have the following question: is there an annex in API 6A which gives guidelines on how to carry out heat treatment furnaces uniformity survey?

    Second Party Inspection VS Third Party Inspection

    I fully agree to what above stated. Moreover, with reference to EN10204 3.2, consider that many manufaturers carry out pre-tests before notifying a Third Party for "official" test. Manufacturer always try to discharge such costs on buyer, having as a result a more expensive price than a...
