ASME cylinders are manufactured to ASME specifications in facilities with a Quality Management System certified to ISO 9002 requirements.
ASME Certified with No 12-Year Recertification
Unlike DOT cylinders, ASME propane cylinders do not require recertification after 12 years from the date of manufacture. This provides a convenient long-term propane storage solution without the need for periodic recertification. The tank is also backed by a one-year manufacturer's defect warranty.
