CONSTRUCTION AND APPLICATION

Type 2 CNG Cylinder 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.
The construction of a Type 2 CNG Cylinder involves a metal liner that is hoop-wrapped with a composite material along the straight sides of the cylinder.
The metal liner can withstand the operating pressure independently, while the composite wrap provides additional strength and safety.
This construction balances the durability of an all-metal cylinder and the lightweight benefits of a fully composite cylinder.
Type 2 cylinders are used in various applications, including vehicles that run on CNG.
They balance weight and durability, making them suitable for many users who require a lighter option than Type 1 but do not need the extreme lightness of Types 3 and 4.

Selecting the Ideal Gas Cylinder: Type 1, Type 2, Type 3, or Type 4?

Each type of CNG cylinder has advantages and considerations, making them suitable for different applications based on weight requirements, durability, and cost-effectiveness.

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.
