Once a cylinder has successfully passed all visual inspection and hydrostatic re-test requirements, it is to be permanently marked with the re-test date, month and year, and licensed re-test agency’s number in the proximity of the previous hydrostatic test date. The pressure vessel (fire suppression cylinder) must be decanted, cleaned then dried. (ii) The cylinder is used exclusively for air; argon; cyclopropane; ethylene; helium; hydrogen; krypton; neon; nitrogen; nitrous oxide; oxygen; sulfur hexafluoride; xenon; chlorinated hydrocarbons, fluorinated hydrocarbons, liquefied hydrocarbons, and mixtures thereof that are commercially free from corroding components; permitted mixtures of these gases (see § 173.301(d) of this subchapter); and permitted mixtures of these gases with up to 30 percent by volume of carbon dioxide, provided the gas has a dew point at or below minus (52 °F) at 1 atmosphere. Reference the table in this paragraph that specifies cylinder retest pressure and retest period. We also provide hydrostatic testing services for fire extinguishers, scuba tanks and other gas cylinders to ensure there are no leaks and they are in good operating condition. Hydrostatic (Hydro) Testing for CO2 cy linder is a process where components such gas cylinders are tested for strength and leaks. The reason for this is to ensure the tank is capable of holding gas pressures far greater than it is normally required to. This test ensures the cylinder can safety hold the maximum fill pressure. All DOT-3AL marked CO2 cylinders are to be inspected and hydrostatically re-tested every five years as required in CFR Title 49 Part 180.205(c).
