1.0 OBJECTIVE1. Find the equivalent ASME sectionWI design pressure for tanksTK-2 and TK-3.2. Determine whether the lack of doubler plates under the lifting lugs is acceptable.2. Find the margin of safety against exceeding the 4 9 CFR 178 .245 equirements for the lifting lugs.

3.0 ASSUMPTIONS, RESULTS,AND CONCLUSIONSAssime:1. That both tanks are filled o their design capacity with sodium, and have piping, insulation and heatersremovedso they appear as on heir reference drawings.2. The weight forTK-3 is assumed to be 5000 b, which isgreater than the weight stated on the drawing toallow for insulation and app utances. .The lugs for both tanksare he same, so the lugsfor TK-2 will not beanalysed since the tankweighs only 500 lb.3. The lifting arrahg ement s similar to that show in the sketch.4. The tankheads are an ASME configuration, with the same thickness as the pipe. The cylindricalportion ofthe tankwill then control the design pressure, and no stess analysis is needed for the head or head-cylinderjoint.Conc1 s ons:1. Considering only the primary stress in the tank cylinders, TK-2 has a calculated design pressure of 45 0 psi,and that of TK -2 is 293 psi.Both exceed the design pressure requirement of 49 CFR 425 forDOT 1 portabletanks.2. No doubler plates are necessary.3. The liiing lug attachmentweld has a factorof d e t y of 9 against failure, and meets the requirement of 49CFR 178.245.

3.0 ASSUMPTIONS, RESULTS,AN D C ON C LU S ION SIt is conservatively assumed th at both t anks are filled to their design capacity with sodium, but have piping, insulationand heaters removed so they appear ason their reference drawings.The weight and center of mass fo r TK-3 are calculated since. the drawing does not show the cen ter of mass location. Thecalculated total mass is less than that on the drawing, so the tiedown calcu lation uses a mass slightly arge r than that onthe drawing. The mass and center of mass location of the smaller TK-2 are taken from the reference.The tiedown system presented in this chapter is adequate to restrain tanksTK-2 and TK-3 against the forces required forsecuringhazardous materials by 4 9 CFR 393 when the tiedown is built to the sketches in appendix 8.4.1, fastened to thetrailer deck, and when the tank s secured with straps.

Plan view,tank TK-3 on trailer.Tiedown method for TK-3: fasten 2 wood cradles to a wood traile r deck with nails to prevent lateral m otion. As shownin the sketches in section8.4.1,each cradle consists of two 4x4wood frames with plywood sheathing. Each crad le issecured to the deck w ith 1030d spikes,using 5 nails per frame, evenly spaced in he horizontal frame member. Twostraps over the tank and secured to th e side of the trailer provide longitudinal and vertical restraint.

Due to the small size of the tank, pallet is needed to raise it so straps can have a good lead. It will be carried on thesame trailer with TK-3, but with the cylindrical axis across the w idth of the trailer.
