Our DOT vessels can be designed and fabricated in a wide range of sizes and configurations for use in transportation assemblies.

CP Industries is approved by the DOT to manufacture 3A, 3AA, 3AAX and 3T specification pressure vessels and to perform requalification testing of these vessels, normally required at five-year intervals.

CP Industries adheres to these exacting specifications when building all DOT vessels, ensuring a reliable product that meets all safety standards. Every finished vessel is tested and inspected as specified, with a final hydrostatic test to 5/3 times the design service pressure.

The DOT’s legal jurisdiction is limited to the U.S.; however, DOT vessel design specifications are recognized and accepted in many other parts of the world, including South America, Asia, Africa and Australia.

UNDER NO CIRCUMSTANCES are gases other than those authorized by the DOT to be used in these vessels; otherwise, the structural integrity of the vessels can be impaired and result in catastrophic failure, personal injury and/or property damage.
