    Engineering Companies and Licenses

    Stevenal makes and excellent point. When I typed that sentence "A has a contract with C to provide a stamped design" should have been an immediate tip off. The state board in this case (as indicated parenthetically in the OP) requires firms offering engineering services to have a designated...

    Engineering Companies and Licenses

    Here's an interesting ethics question. In this example, we have companies A, B, and C. A = Technical Services company, no license to practice engineering (the state requires it). This company used to have a license, but let it lapse. B = Engineering company - has a license. C = Big Client. A...

    Expired License

    Regarding the OP (haven't read this whole thread, sorry): For future reference, you don't need your boss' input or approval to report what you saw to the board.

    Sarcasm

    Looked in the rules and "mollycoddle the poster" was not there. Sorry, that was a bit sarcastic wasn't it? :-D Just messin' with ya. :-)

    Other 'job'

    The first mistake here is treating a non-exempt employee like and exempt one. Non-exempts will have a whole different attitude and would never expect to be fired over not wanting to work overtime. You're the exempt guy. You fill in for him this fall and hope business picks up enough (or...

    Responsible Charge - What does this mean to you?

    RVSWA and Badger seem to be confusing the duties of the designated engineer and the responsible engineer - at least the way it is written in the state of Washington. With a smaller firm, certainly there may be only on PE, but in a larger firm, a PE is expected to provide "direct supervision" to...

    The Meaning of an ASME Code Stamp

    Ok, just to clarify, the inspector reviews calcs for accuracy, but not that the code was applied in proper fashion (adequacy)? The reason I ask, is that I'm on a requirements review team, and some are saying that if we come across a tank that is code stamped, then we can assume it was designed...

    The Meaning of an ASME Code Stamp

    This may actually apply to more than ASME BPVC, but I was wondering what it means exactly to have a stamped/certified vessel (or piping)? Does that mean it was fabricated to the code? Or designed as well? What I'm getting at, is does the inspector who stamps also review the design calculations...

    Job Interview - Technical Questions

    Congrats on the job. For any others interested, I've heard and USED this one. Define "work." This usually catches the post-grads off guard. If they are in one mind set, they want to describe what their work day would be like. If they are still in an academic mindset, they will say: W = F x...

    Pneumatic Test Pressure Basis - Why Less then Hydrostatic?

    Anyone know why the pneumatic test pressures of B31.1 and B31.3 are less than the hydrostatic (110% vs 150%)? Best I can come up with is safety. Pressure is pressure (given all other conditions identical), which means the hydrostatic test is more rigorous.

    Increasing Operating Level of Underground Nuclear Waste Tanks

    Yes, I forgot to meantion we are also doing an ANSYS FEA on the tank to verify loading and stress on the shell. The risk assessment is a great idea. Thanks.

    Increasing Operating Level of Underground Nuclear Waste Tanks

    We are trying to determine a path-foreward for increasing the operating level of our underground nuclear waste storage tanks. Background These are double-shell tanks, nominally 1 million gallons (75 foot dia primary, ~82 foot dia secondary). They were built to ASME BPVC Section VIII Div 2...

    Centrifugal Pump Suction Conditions

    Here are details requested by Andrew "supplier" above. Cyclone inlet pressure: 15psig; cyclone inlet/outlet datum elevation: 0.00; cyclone outlet pressure: 1.00 psig; pump suction datum elevation: -4 ft; line size between cyclone and pump: 6-inch sched 40 stainless; qty of 90 deg bw...

    Centrifugal Pump Suction Conditions

    Thanks for the reply. However, your answer seems to contradict itself. You agree that pumps don't "suck," yet you say they reduce the pressure at the inlet allowing system pressure to "push" more liquid into the pump. But if the system HAS pressure, then why does the pump...

    Centrifugal Pump Suction Conditions

    We are installing a centrifugal pump downstream of a close-packed hydrocyclone. The hydrocyclone vendor was concerned that the pump would draw on the cyclone and reduce cyclone performance. It is my understanding that centrifugal pumps don't "suck." Are there any conditions that...

    Slab On Grade Problem

    First, I'd like to thank you all for responding to this question and giving me such informative and useful responses.<br><br>To clear things up regarding radiological contamination concerns, I'd like to say something about incorporating the slab into the grade.&nbsp;&nbsp;Yes, this could be...

    Slab On Grade Problem

    We're trying to assess the integrity, or come up with assumptions for analysis with regard to an existing slab-on-grade at our site.<br><br>Due to radiological contamination reasons, we plan on pouring a new slab over the existing slab.&nbsp;&nbsp;Removing the old slab is not an...
