    ASME B31.1 Power Piping Code - Pipe Support Welding

    ASME B31.1 is silent on the pipe support requirement for frame type support. There is also no guidance on how this support is to be design. Frame type support refers to pipe support composed mainly of structural steel members. Examples are; pipe boxed in structural steel members (guide), a beam...

    Branch Connections in Recip Compressor Piping

    It is correct that the area branch replacement method is only for internal pressure design. B31.3 requires a stress reduction factor for cyclic loading. If the compressor loads and unloads once a day, consider it one cycle per day, 365 cycles per year and 7,300 cycles for a system life of 20...

    Tunneling

    A closed circulating water conduit of 233 meters wide by 6.25 meters depth is planned to be tunneled through a highway. The highway is expected to carry loads of say 60 MT by 12 meters long trailer. It is planned to have the conduit located 4 meters beneath the highway. I need advise what is the...

    Responsibiltiy for Smoke Control Systems

    In my place of work, there is a debate as to who is responsible for the design of the smoke removel/control system. The HVAC engineer believes that the Fire Protection Engineer (FPE) is responsible for the design of the system. The FPE believes otherwise.<br> <br> The HVAC engineer believes that...

    Froude number and Steam vent/drain

    A heat exchanger that uses superheat steam to heat cold steam is being provided with drains. The drain shall flow by gravity and at the same time be capable of venting the steam (flash steam)as the drain flow downwards. Suggestions on how to proceed on the design is highly appreciated.

    Long piping - expansion

    This is interesting! Pipe expansion is based on the installed temperature and the operating temperature or design temperature. One would only think that the difference in the operating temperature and the design temperature are wide apart so that the anticipated thermal expansion did not...

    API 650

    No, I have not checked with ASME. API 650 is for atmospheric pressure storage tank. The ASME Code is for pressure vessel. The two are separate standards for separate applications. Para. U-1, letter (c), number (8) of ASME Sec. VIII, Div.1 exempts such storage tanks from the jurisdiction of ASME...

    API 650

    I would like to receive some advises on the criteria for allowable load on field fabricated storage tank based on API 650. What is the acceptable load criteria for a combination of load such as dead load, live load, earthquake and thermal load acting together at the same time?

    Above ground storage tank

    What is the API 650 acceptance criteria for load combination? Say, the load cause by weight, pressure, temperature, and earthquake combined together?
