Specifically, you\nask what criteria establishes the minimum design metal temperature (MDMT) marking that\nmust be included on the name plate on a cargo tank motor vehicle (CTMV) in accordance\nwith the American Society of Mechanical Engineers Code (ASME Code), as prescribed in\n§ 178.337-17.\nSection 178.337-17(a) specifies that each cargo tank certified after October 1, 2004 must have\na corrosion-resistant metal name plate and specification plate permanently attached to the\ncargo tank itself or the CTMV chassis. Further,§ 178.337-17(a)(3) states that ifthe\ninformation required by this section is displayed on a name plate required by the ASME\nCode, the information need not be repeated on the specification plate. To answer your\nquestion regarding the rp.arked MDMT, it is the lowest temperature permitted according to the\nASME Code. Please note that the MDMT is generally not the same as a pressure vessel's\nlowest design temperature in the marking required by§ 178.337-17(b)(4). A cargo tank's\ndesign temperature range is based on operating conditions, and is the lower of environmental\n(ambient) temperatures or the fluid temperature in or transiting the pressure vessel.\nI hope this information is helpful. Please contact this office should you have additional\nquestions.\nSincerely,\n/)\nOL#l~'\n(/ T.

Based on the prior \"Operational\" premise, we should be telling industry that this\nentry is not the ASME \"MDMT\" and they should be putting in temperatures that ret1ect their best judgment of\nthe ambient/environmental temperatures the tank might operate in.\nfJattie - can you get something put together to convey this to industry/Thanks\nStan\n-----Original Message-----\nFrom: Greg McRae Imailto:Greg.McRae@trin.flSill\nSent: Tuesday, June 29, 2004 10:49 AM\n1\n\n<<>>\n\nTo: Staniszewski, Stanley \nSubject:\nRe: New regulations for MC-331 Nameplate information.\nWe are going under the assumption that Design Temperature will be a requirement on the nameplate.

That become effective in Oct.\nIn paragraph 178.337-17 ,Markings, (b) 4\nIs the stamping required in line 4 the same that is already required by ASME? An example of the stamping on a truck tank\nnameplate of SA-612 material is as follows,\nMAWP 250 psi@ 125 degrees----- (Propane at 125 degrees is 250 psi vs. the material max.range is 200 degrees)\nMDMT -8 degrees@250 psi\nI hope the MDMT doesn't confuss someone in the middle of winter in Minnesota on a -40 degree day and think the tank\ncan no longer can be operated.\nRegards,\nGreg McRae\nEngineering and Technical Director\nTrinity Industries Inc.\nLPG Container Div.\nCEM Group\nph.214-589-8559\nfx. 214-589-8303\n2","truncated":false,"body_characters":5202}
