    Defining ISO9001 clauses on Validation and Verification in the context of pressure vessels

    in very basic terms you have your assumptions reversed: Validation is the assurance that a product (or service) meets its user's requirements, i.e. calcs for a pressure vesel design. Verification is the determination of a product's (or service's) conformance to original specifications, i.e...

    machining witness or reference point explanation;

    Mfgenggear, i agree and understand the machining methods you mention, but i have performed many searches and not found a document to reference. i guess i will put it on the engineer and machine shop to answer how they can assure planarity prior to placing the equipment onto the pedestals...

    machining witness or reference point explanation;

    mfgenggear, no place on the bottom was machined each skid weighs 16tons, so flipping the skid becomes a problem. mikehalloran, to complicate the issue, i have 6 pedestals @ different heights (3 pairs)and piping connections that have to match up to existing piping. so leveling to such tight...

    Steam Reheater Mystery Marks

    i am assuming that this is a relatively new construction. i agree with the inspectors except for the 3rd picture of the bend. i would say that is a thermal crack. regardless, if you did not find evidence of FOD (foreign object damage), like loose material in the bottom of the vessel, i would...

    machining witness or reference point explanation;

    Mike, thanks for the response. what you have described is what i have observed over the years. my quandry is, i was looking at a skid that has some pedestals welded on it and the tops had to be machined "flat & true" to the base of the skid (within .001"). however, the drawing nor the skid...

    machining witness or reference point explanation;

    (not for CNC programing, i have already read up of zero reference points - tool, machine & part) but to establish a beginning point in relationship to the whole part? i am not a machinist but have seen some machining operations and heard machinists use the term witness point or reference point...

    What do you charge for a second site visit?

    i normally call to confirm any site visits. the cost of a phone call beats the hassle you go thru in your situation.

    in-process NDE requirements question

    stanweld - agree & have heard the PO reasons for not doing NDE, even informational weldtek - agree on the Minimum requirements. seems butt welds are covered more than any other type of welds for NDE & i do not seem to have the same uphill battle with Sec VIII fabricators/buyers

    in-process NDE requirements question

    FYI, i did look @ B31.3 344.7 and it says "when specified in the engineering design". may original question remains. gtaw, your post is why i asked this question. i cannot seem to get it thru to some that a little in-process NDE is cheap compared to rejects or failures or safety

    in-process NDE requirements question

    does any Code prescribe or require in-process NDE (mt, pt,ut,etc)? i have searched various Codes and cannot find any requirements. everything i see is for final inspection. TIA
