ISO 11120


For international transportation, International Organization for Standardization (ISO) 11120 is the internationally recognized design standard for seamless steel tubes of up to 3000 liters capacity.

CP Industries designs and manufactures seamless pressure tubes that meet the ISO 11120 standard. Working with a notified inspection body in the United Kingdom, CP Industries has obtained approvals for these tubes to the European Transportable Pressure Equipment Directive (TPED). Tubes bearing the TPED marking are approved for transportation in all of the countries in the European Union.

In addition to TPED-approved ISO tubes, CP Industries has merged ISO standards with DOT regulations to allow us to offer tubes that are dual certified to both USDOT and European ISO 11120/TPED — thus providing our customers with steel tubes that have the flexibility to satisfy regulations on both sides of the Atlantic.
