Successful use of gas cylinders by consumers is not only based on their operational characteristics. But, above all, reliability and safety. For the production and operation period, there were no cases of failure – with a safety margin of 2.6 P (P-working pressure). Pressures of 78 – 82 MPa would be destructive in automobile cylinders, and the cyclic durability reaches 20,000 cycles, with a guaranteed 15,000. Each batch of gas cylinder tests confirms safe for use before reaching consumers.

When it comes to technical products, following the correct rules of operation and maintenance is vital to prevent dangers. LPG vehicles are no exception. It reduces the risk of self-ignition. Through evaluating physical and chemical parameters of gases such as temperature and concentration.

For an ignite or explosion, fuel needs to mix with air in gas tanks. The presence of gas in a cylinder under high pressure prevents air from entering. In tanks containing gasoline or diesel fuel, the vapours mix with air. Liquefied petroleum and natural gas have lower temperatures and concentration restrictions than liquid petroleum fuels. Gaseous fuels are safer when following the regulations of operation and maintenance. In the surface layer, the gas evaporates and forms an explosive mixture with air. Making liquefied petroleum gas is more dangerous in operation.

Break test result. When natural gas leaks, it rises approximately twice as fast as air and dissolves into the atmosphere. Most countries in Europe have CNG filling stations in urban areas of residential and public buildings. With countries using natural gas to refuel vehicles. Car gas cylinders must meet the margins of safety and condition of non-fragmentation destruction before use. Making them far less dangerous than they’re made out to be.

Quality Control

During the production,  step-by-step control is carried out with a mark of the quality of each operation in a special technological passport for absolutely every cylinder.

Green Tech’s Quality Management System includes certifications  ISO 9001, IATF16949, ISO 45001 and ISO 14001

Here are just a few of these tests:

  • Flame exposure: The surface of the cylinder is loaded to working pressure then
    heated to 590°C while the gas is vented through a safety device.
  • Resistance test to defects of the cylinder’s composite shell: Defects are applied to the shell at a certain depth and length. The cylinder must withstand at least 3000 cycles at pressure loading 1.3 P.
  • Prolonged exposure to loads: A cylinder with a pressure of 1.3 P is maintained at temperatures of 65+°C for 1000 hours. In the subsequent burst test, the balloon
    must withstand pressure no less than the calculated one.
  • Impact resistance: The cylinder is dropped three times onto a concrete surface from a height of 1.8 meters in different positions, after which it must withstand at least 3000 cycles of pressure loading 1.3 R.
