    How many copies of the BPVC does a cargo tank maker need?

    metengr, yes, the IHS subscription does seem like it could be a good choice -- thanks for pointing it out. And "thank you" to you and ASMEQC for your opinions on how many copies are needed. I appreciate all. -Sean

    How many copies of the BPVC does a cargo tank maker need?

    Good question, metengr! Section XII is indeed intended for transport tanks, but it's not yet allowed as an *alternative* to the others, for haz-mat service (which is what I'm trying to figure out). Haz-mat tank makers still have to build to the other 4. The DOT seems to be trying to get XII...

    How many copies of the BPVC does a cargo tank maker need?

    Hello: If a small-ish tank trailer manufacturing company is getting started and needs to buy the needed ASME B&PV Code, how many copies of the *same* sections would it need? A shop like this, intending to build to DOT-406, DOT-407, and MC-331, needs BPVC Sections II (Part A and B), V, VIII...

    Transport tank design under BPVC Section VIII -- using design margin = 4.0 or 3.5 ?

    I hadn't heard the "VIII Light" comment about XII before, but I guess that sounds about right, from what I can tell. You're right that XII is more *technically* appropriate for transport tanks -- that's what it was created for, with input from the DOT. But the hazardous materials reg's haven't...

    Transport tank design under BPVC Section VIII -- using design margin = 4.0 or 3.5 ?

    Thanks for your thoughts, jtseng123. I think that vendors who build *transport* tanks for hazardous materials have it a bit different: they *have* to get an ASME code stamp in order to comply with the hazardous materials regulations. This includes some very common tank trailers and tank...

    Transport tank design under BPVC Section VIII -- using design margin = 4.0 or 3.5 ?

    Hello: The current US hazardous materials reg's require that transport tanks for many commodities (such as non-pressure liquid tanks for gasoline built to MC-306/DOT-406, and high-pressure tanks for propane built to MC-331) use the 1998 Edition of ASME BPVC Section VIII, which calls for a...

    Hazardous Materials Reg's incorporate by reference the 1998 Edition of BPVC - any effect?

    Hello: The U.S. Hazardous Materials Regulations (HMR) (at 49 CFR Parts 171–180) incorporate by reference the 1998 edition of the ASME Boiler and Pressure Vessel Code (BPVC), which has now been superseded by several updated editions. The HMR primarily affects the design, manufacture and repair...
