    Support saddle

    To be honest, with the size and weight of the pipes that the saddles would be used for, I would not recommend trying to go outside of the ASME code for this. Should the saddles fail, serious consequences could result.

    Need advice on FEA results

    It is hard to say for sure without seeing the actual FEA setup and results. You could be getting false stress concentrations depending on how the analysis was setup. I agree with TGS4 in terms of the conservative aspect. When in doubt I usually go for the more conservative route to be safe...

    Codes (British Standards to US Standards)

    I am not familiar with the BS EN 13280:2001, ASME RTP-1, or ASME code section X codes. In terms of converting the engineering notes I would simply look at each test and find the closest possible similar test in either one of the ASME codes. From the experience I have had with codes, quite a few...

    Gas Coolers offshore, detecting air short circuiting

    Not sure if this would work for you (depending on the time and resources available) but you could setup a simple test bench. Place the coolers in series as they would be during operation. Attempt to replicate the operational parameters as much as possible. Measure the incoming temperature and...

    Valve designation

    I agree with Mike. There is no standard. Each company sets up their own format. For example, a 2" Figure 1502 low torque service plug valve has a part number of 2PV722MFRAN where the 2 represents the 2" size and the rest is unkown to the end user. For the most part I would contact the supplier...

    Codes (British Standards to US Standards)

    As a question, are you simply converting the sheets for records or is there an actual tank or tanks that you are trying to get certified via US codes. If the later is true you should make sure that the US code will allow this. At the company I work at, we tried a similar thing to have a US tank...

    Heat Rejected from boiler into boiler room

    Hi BronYrAur, Unfortunately with your scenario there are still a lot of unknowns but I will do my best to ensure that all my assumptions are fully stated. After looking through the PDF that you attached, I perceive the combustion efficiency as the overal efficiency of the combustion reaction...

    Fuel Gas Bolier Tested with N-1 Burner

    It really depends on the design of the boilers. For example, depending on the design, runing the boiler with two of the three burners operating could create a situation where fuel pressure increases enough to damage a line or cause a leak. Another scenario could be that the boiler is designed to...

    Exhaust Plume Radiation Model

    Macmet, If you want to learn more about radiation heat transfer from gases you can also try Fundamentals of Heat and Mass Transfer 6th edition by Icropera, DeWitt, Bergman, and Lavine. Chapter 13 discuses radiation heat transfer and Section 13.4 goes into some detailed equations regarding...

    Heat exchanger idea

    You would need to provide a lot more information to be able to use any kind of calculations to determine if the 10 square feet is enough. For example, how are the heat exchanger tubes arranged? If they are too close to each other you could end up reducing your effective heat transfer due to each...
