Type 2 CNG Composite Cylinder, which can store natural gas under pressure 20MPa or 25MPa 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 first category is seamless alloy steel cylinders (CNG-1).
CNG-2 is a carbon fiber cylinder with steel or aluminum lining and a barrel reinforced
with long fibers impregnated with “hoop winding” resin.
The third 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.
A complete automotive CNG Composite cylinder has a cap, a valve, and a safety relief device.
The cap protects the valve, and the safety relief device on the valve should be of
the rupture disc-fusible plug combination type.
