Type 2 CNG Composite Cylinder which can storage natual gas under presure 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 4 categories available in CNG gas cylinders.
The first category is seamless alloy steel cylinders (CNG-1).
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 third category is composite gas cylinders with aluminium liner plus carbon fibre fully
wound and glass fibre ring wound reinforcement (CNG-3).
The fourth category is the composite gas cylinder with plastic liner plus carbon fibre
full winding and glass fibre ring winding reinforcement (CNG-4).
Each of these Compressed Gas cylinders has its own 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 cylinders 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.
