PART 178_SPECIFICATIONS FOR PACKAGINGS--Table of Contents

 

               Subpart H_Specifications for Portable Tanks

 

Sec. 178.245-4  Tank mountings.



    (a) Tanks shall be designed and fabricated with mountings to provide 

a secure base in transit. ``Skids'' or similar devices shall be deemed 

to comply with this requirement.

    (b) All tank mountings such as skids, fastenings, brackets, cradles, 

lifting lugs, etc., intended to carry loadings shall be permanently 

secured to tanks in accordance with the requirements in Section VIII of 

the ASME Code (IBR, see Sec. 171.7 of this subchapter) under which the 

tanks were fabricated, and shall be designed to withstand static 

loadings in any direction equal to twice the weight of the tank and 

attachments when filled with the lading using a safety factor of not 

less than four, based on the ultimate strength of the material to be 

used. The specific gravity used in determining the static loadings shall 

be shown on the marking required by Sec. 178.245-6(a) and on the report 

required by Sec. 178.245-7(a).

    (c) Lifting lugs or hold-down lugs may be added to either the tank 

or tank mountings. If lifting lugs and hold-down lugs are added directly 

to the tank, they shall be secured to doubling plates welded to the tank 

and located at points of support, except that lifting lugs or hold-down 

lugs with integral bases serving as doubling plates may be welded 

directly to the tank. Each lifting lug and hold-down lug shall be 

designed to withstand static loadings in any direction equal to twice 

the weight of the tank and attachments when filled with the lading using 

a safety factor of not less than four, based on the ultimate strength of 

the material to be used.

    (d) All tank mountings shall be designed so as to prevent the 

concentration of excessive loads on the tank shell.

    (e) A DOT 51 portable tank that meets the definition of 

``container'' in Sec. 450.3(a)(2) of this title must meet the 

requirements of parts 450 through 453
