    Women in Engineering.

    As an engineer I would never ignore statistics, and I would never doubt that many women have experienced job discrimination, but as a female engineer I can't say I have ever faced any kind of professional discrimination in work or at university and have (to my knowledge) never been...

    UT Thickness Results are inaccurate for an on-line pipe?

    Thanks for all the helpful information! Did some more digging and it looks like the readings are taken from random points across the line - the reason the pipe looked as if it was getting thicker or thinner each year was because the *minimum* thicknesses were tabulated over the years -...

    UT Thickness Results are inaccurate for an on-line pipe?

    Thanks for all the helpful responses! The pipeline is carrying gas, so no fluid solidification. I did ask about a double check before we started making progress towards replacing the pipe - but I'm only here until September and the earliest another UT check can be performed is December!

    UT Thickness Results are inaccurate for an on-line pipe?

    Thanks for the response! It's consistent all across previous years. The pipe has a nominal of 9.52 (let's say) and 6 or 7 thickness readings (from separate occasions) can be above 10! This could be because of a tolerance, but the pipe switches from 9.6mm in 2008, to 5.8mm in 2009, to 10mm in...

    UT Thickness Results are inaccurate for an on-line pipe?

    I had some UT thickness results back claiming a pipe was significantly thicker than its nominal thickness! We believe that this is because the pipe was on-line at the time, so the temperature of metal altered the speed of sound within the material, making the UT device think that the pipe was...
