    Leaving management

    I went from management back to individual contributor, and I don't regret it one bit. I had 17 direct reports, and It wasn't easy to manage them. I missed doing engineering, and after four years I begged for my old job back. I had a hard time getting management to agree to the move. It took nine...

    Health Insurance and Consulting

    Good point gravityandinertia. I never looked at it that way. I just wanted to see what others are doing to provide health insurance for their families. Thanks for the insight.

    Health Insurance and Consulting

    I have always wanted to go out on my own and try consulting. When I look at the cost of health insurance for my family, it makes me reconsider every time. Is there an affordable way to get health insurance for an independent consultant. Any insight from others on this forum is greatly...

    MDMT determination for PWHT vessel

    I am working on an MDMT determination for a vessel that has PWHT because it is in caustic service. PWHT is not otherwise required. If a vessel has PWHT for service, do I get to take the 30 deg reduction in MDMT that is allowed by paragraph UCS-68(c). I am having trouble determining exactly...

    Company B

    I had a similar situation a few years back. I had a job that I liked with good pay. I received an offer of a 20% pay increase from another company. I felt like I needed to accept the higher offer, so I went to the new company. I hated the new job, I wished that I could have my old one back...

    Friction Factor to use in bolt torque formula

    I am using a Nickel Anti-Seize thread lubricant on the studs of a flanged joint. I am trying to calculate the target torque to achieve the desired bolt stress. I am having trouble determining the proper coefficient of friction to use in the formula. The product data sheet for the particlar...

    Using Fig. UCS-66 for SA-333 Gr. 3

    Thanks for the reply doct9960. I agree with you that it goes on curve B. The reason that I asked my question is that it does not make sense to me that this material should be on curve B. I just wanted to see if I was missing something. It is equivalent to SA-203 material except that it is pipe...

    Using Fig. UCS-66 for SA-333 Gr. 3

    I am trying to use Fig UCS-66 for a nozzle neck constructed of SA-333 Gr.3 material. The shell of the vessel is constructed of SA-203 Gr. E material. In the notes section, SA-333 material is not assigned to any curve. I assume that it would have the same requirements as the SA-203 Gr. E since...

    Re-rate of pre-1968 vessels

    The only documentation that I have for the code of construction is in the general notes on the fabrication drawings: Design, construction and welding to be in accordance to the 1952 edition of the ASME code for unfired pressure vessels.

    Re-rate of pre-1968 vessels

    I am not actually doing a rerate of the vessel. We have vessel fabrication drawings but no certified documentation for the vessel rating. There is not a U-1 and the nameplate is missing. I am to perform the calculations to verify the rating of the vessel. I was under the impression that you...

    Re-rate of pre-1968 vessels

    What I have is a vessel built to the 1952 edition of the code. The material is A-212-B F.Q.

    Re-rate of pre-1968 vessels

    Does anyone know the reason why vessels that were built to the 1968 or previous editions of the pressure vessel code cannot be re-rated using the current code?

    UKRAINE STEEL

    Thank you for your replies. The manufacturer was aware of the material restrictions at the time of quoting and the end user has asked that the material be replaced. So that is how we are proceeding.

    UKRAINE STEEL

    I am having some nozzles added to a vessel. As a part of the specification for the alteration, it states that materials from Eastern Europe or Russia need to be approved on an individual basis. The vessel fabricator has manufactured some of the nozzles using SA106 GrB material from a Ukrainian...

    Nozzles on a blind flange

    I am adding (3) 1-1/2 nozzles to a 20" 300# manway cover for use as termowell connections. My nozzles meet the requirements of UG-36(c)(3)for not needing re-inforcement. When I do an appendix 2 calculation for the flange thickness, the required thickness is greater than the 2-9/16" thickness...
