CNG production requires long and complex steps; in the end, CNG remains gaseous with essential substances such as methane, nitrogen, CO2, propane, and ethane still contained within.
CNG boasts superior heating values than petrol; where 10 liters of petrol could take a car 100km, only 6-7 liters of CNG would suffice.

ISO11439 CNG-1 Standard Compressed Gas Cylinder

CNG Gas Cylinders, which can store natural gas under pressure 20MPa or 25MPa, are made of 4130X
seamless steel tube with ISO9809-1/ISO9809-3/EN/DOT approval.
which are explosive pressure vessels containing flammable and explosive gases.
The storage pressure for automotive cylinders is 20MPa.


There are four categories available in CNG gas cylinders.
The Type 1 category is seamless alloy steel cylinders (CNG-1).
Type 2 CNG-2 is a composite gas cylinder with steel or aluminum lining and a barrel reinforced
with long fibers impregnated with “hoop winding” resin.
The Type 3 category is composite gas cylinders with aluminum liner plus carbon fiber fully
wound and glass fiber ring wound reinforcement (CNG-3).
The fourth category is the composite gas cylinder with plastic liner plus carbon fiber
full winding and glass fiber ring winding reinforcement (CNG-4).

Each of these Compressed Gas cylinders has its advantages and disadvantages, and it depends.

The main cylinders used worldwide are steel cylinders, generally made from high-quality
chromium-molybdenum steel, and the ISO 11439 and ECE R110 standards can meet
the requirements of most countries.
CNG pressure in bar
Worldwide, most vehicle cylinders are rated to handle a working pressure of 3,000 psi (200 bar);
In the US, however, the standard pressure rating for vehicle cylinders is 3,600 psi (250 bar).

How much gas is in a CNG cylinder?

A 12 kg cylinder contains 60ltrs of water capacity; 5 liters equals one kilogram; therefore, its maximum CNG load capacity is 10kgs depending on the pressure in its gas station.

DSW holds ISO9001 and IATF16949 certifications as management systems certifications and ISO9809, ISO11439, and ECE R110 certifications to approve CNG cylinder production.
