The United States Department of Transportation has granted to FIBA Technologies Inc special permit DOT-SP 14453, which authorizes a 10-year requalification cycle on certain, compressed gas tube trailers and ISO skid containers.
This special permit requires state-of-the-art, ultrasonic examination (UE) to assess the integrity of the cylinders and tubes. The permit works in conjunction with the recent DOT requirement to perform inspection of the OD neck threads on tubes mounted in a tube trailer or ISO frame bundle.
