    Excessive construction project weld reject rate

    I have read a lot of posted data relating to weld reject rates and what people and or projects believe to be an excessively high reject rate. Regardless of the perceived acceptable rate, all rejects get negative press and doesn't matter if its based on skills, materials or...

    Valve identification for NACE Valves in the field

    I'm wanting to know if there is a surefire way to identify if a valve is NACE compliant in the field? Please note, As a project gets delayed or extended, tags become illegible or simply fall off the valves. Tracking down the MRR / MTR is sometimes a tremendous chore in itself. The lack of tag...

    Pneumatic testing

    Downhand, I'm not sure what Code or Standard you are testing to. ASME B31.3 clearly states the procedure under 345.5. I see where it addresses achieving the test pressure incrementally and holding to relieve the stresses and strains at each increment. Then reduce to design, "before" examining...

    Controlling Pipe Dimensional Quality

    You dont have to ship very many trucks back for the supplier to get on the same page and use the suppliers that do comply with your projects level of expectations. If your not in a position to help direct your Purchasing Contracts folks and Quality people, you just have to make the right...

    AWS D1.1Ed-2008-4.1.3.2-Tack Welder Qualification

    "So does not require revalidation whatsoever" If there is reason to question the welders ability to weld or they haven't used the process for a period of 6 months. See 4.33., which applies to welders, welding operators or tacker welders. (retest after lapse of qualification) It appears that...

    ASME Section V Article 9 Subsection T-923

    I read the ASNT referenced in the previous post and it seems to agree that the requirements are really not standardized. I guess the most direct question would be, what will ASME Section v accept as the equivalent? (1)Would J2 meet their equivalent criteria. (2) Will ASME accept the AWS CWI...

    Post Weld Heat Treatment of Monel

    Just for the record, I wanted to let you folks know that (since I asked the question, I learned) Welded MONEL alloy 400 components normally go into service as welded.(that part I knew) If there is a concern that the enviironment could induce stress corrosion cracking (e.g, steam containing...

    Clansman, Review the Essential Variables for both, as related to the manufacturers recommendations (and label on the wire) They must be welding flat. or horiz., not sure thats a good field wire. -Doesn't AISC refer you to AWS D1.? (for SS or CS) Structural? " There is no Shortcut to...

    holiday inspection

    You should be able to find that information in the Engineering specification used to order and install the pipe. A good rule of thumb is, If the coating was specified, the testing is required. It would seem a waste of money to pay for a coating that doesn't perform as specified. Or wasn't...

    Risk assessment based on exposure time.

    Larger corporations use Recordable Incident Rates and Lost time incident rates to determine saving, based on avoiding accidents and lost times at given, known associated costs. I'm thinking that there is a predetermined cost associated with various incidents posted on OSHA.org or check the...
