    Dog-Legs

    Tman asks about "acceptance criteria." I'm not sure what that means. Why wouldn't you accept a dog leg piping arrangement? Personal or plant preference I presume. As to pennpiper's post, I take the term to mean a change in direction considerably less than 90degrees as in a "L". Maybe I...

    Interviewing Help/Tips

    Tell the truth. You might not get any points for your answer, but dancing around the truth will deduct points. My gut take from your short post is that you need to hone your skills at your present job so that you have credible answers to the teamwork and project deadline questions. If you are...

    Centrifugal Pump Nozzle Loads Verification

    I'll retract the question. I've been away from B31 too long, sorry! B31.1 explicitly shows that E_h should be applied for reaction load calculations. Should have looked before I lept.

    Acceptable to who and on what basis?

    'High energy'' lines

    Does cryogenic cause as much contraction as steam does expansion? It's about the difference in temperatures from the installed temperature. -80C is going to cause roughly the same change in dimensions from a 20C reference point as would +120C. But you can only go so low, whereas steam at 575C...

    Pipework MAWS based on ASME B31.3

    I've often used the latest and greatest version of B31 when doing new piping work in an old facility, so long as the owner did not object. B31 codes have generally grown less conservative and material properties have become more consistent. There is a cost advantage to using the new codes. In...

    Dinosaurs

    It's not stupid if it works, but your boss's opinion of what is stupid holds more weight than your opinion. If it doesn't work, just be mindful of how you present the improvements. Some bosses have an irrational emotional attachment to their masterpiece/piece of crap spreadsheet. From a...

    "I ntelligent" piping material part numbering system

    SRUTGU, If you use a 3D design software (e.g. SmartPlant, AutoPlant, etc) the software developer most likely had some commodity code schema delivered with the software. Look into adopting that before you venture too far down the path of making your own. There are commercial software solutions...

    Piping Material for Flashing Service

    I'm on the EPC side so I don't get to see much of the aftermath. One coal plant I visited had a small mountain of worn-through small bore pipe that they have removed from service over the last several decades. The story is it came from small bore condensate and blowdown lines made of CS...

    Piping Material for Flashing Service

    The ASME B31 codes include a nominal chemical composition of the materials in Appendix A. Otherwise, there are a number of pipe material cross references available on the web, pipe suppliers, etc. ASTM A335 P22 - Pipe ASTM A182 F22 - Forged ASTM A234 WP22 - Wrought Beware the class...

    cement lined pipe spools

    Mikey, The disclaimer about not providing engineering services appears on all my posts. It was not for you, it's a CYA disclaimer for me primarily. The end of it does apply here... the value of my response was equivalent to the price you paid. You might have better luck if you engage a...

    organization strategies

    There are 30+ year people who still struggle with this. It's a habit. Learn and practice it now. David Allen - Getting Things Done Stephen Covey - First Things First Peter Drucker - The Effective Executive [I imagine I'll get a few snarky remarks from the cynics for listing those books...

    Repeat a question from before... same answers?

    No use beating around the bush. Just ask the hiring manager (at an appropriate time during the interview/offer process): 1) What are your expectations for hours per week? 2) How do you compensate for hours worked in addition to your __ hour expectation? 3) How much travel is expected for this...

    Out of practice EIT - shoudl I get a PE?

    If you got cash and a day off from work to burn, you could take the test with just a short review the weekend or two before the test. If you don't pass and your employer doesn't care (or doesn't even know), what's the harm? If you pass... great! - Steve Perry This post is designed to...
