Standard for Design Requirements for Tube Trailers and Tube Modules (Formerly TB-25)

CGA C-29 – Standard for Design Requirements for Tube Trailers and Tube Modules (Formerly TB-25)

CGA C-29 defines basic design requirements for tube trailers and tube modules, manufactured or modified on or after May 11, 2009, to maintain structural integrity during normal conditions of handling and transport. A tube trailer or tube module manufactured in accordance with standard is less likely to have a separation of the tubes from the trailer or bundle or an unintentional release of product when subjected to the multidirectional forces that can occur in a highway collision including a rollover accident. Tube modules shall meet the loading and accident protection standards that are applied to tube trailers.

This standard does not address multiple-element gas containers (MEGCs). The design requirements for a MEGC are found in Title 49 of the U.S. Code of Federal Regulations (49 CFR) Part 178.75.
