    Geodetic elevation question

    Thanks for the input. The monument predates the tank and is consistent with other, newer momuments whose accuracy have been verified. There's been a little shift from the 1929 Datum (1978 adjustment) -- but not seven feet! The surveyor is deceased, the engineering company that designed and...

    Geodetic elevation question

    I'm looking at a drawing of a tank foundation. The drawing says "0'-0" elevation equals 32' geodetic elevation". I go out to the field. Not far from the tank is a surveyers monument. It has an elevation of 23.94'. The base of the tank sure isn't 8 feet above the monument. It's only a few...

    304 SS vs A333 CS for low temperature ethylene

    Hi. We bring in ethylene through a 2" sch 160 pipeline, at pressures up to 1400 psig. The pipeline is A53 carbon steel, with a minimum temperature rating of -20F. In the event of a sudden depressurization, the temperature could drop as low as -40F. So we want to replace the pipeline with...

    Where to locate burner?

    My company is installing a thermal oxidation unit. The planned location of the burner is within 20 feet of the electrical shop. Hmmm. Are there regulations governing how close the unit can be to an occupied building, or the process, or a storage tank? If so, where would I find them? Many...

    Best Estimation Manual?

    As part of my job I need to estimate piping materials and installation costs. However, before my boss will approve the cost of $137 for a 2007 Means book, he wants to know how it compares with other estimation books. I was forced to admit that I don't know any other estimation data sources...
