CNG Gas Cylinders

Compressed CNG Gas Cylinders

CNG Gas Cylinders
Compressed Natural Gas cylinders (CNG cylinders) is
a popular alternative with truck, transit and refuse fleets.

CNG Gas Cylinder

CNG cylinders are specially designed high-pressure containers utilized for storing compressed natural gas.
These cylinders are constructed from a unique steel alloy and boast a seamless construction.
The gas storage pressure for vehicle CNG cylinders typically reaches 20MPa (3,000 psi).

DSW offers a comprehensive range of industrial gas cylinders, including CNG gas cylinders, in seamless and welded models for storing, transporting, and dispensing industrial gases.

Compressed gas cylinders find regular use in various settings, such as science and engineering buildings, machine shops, retail establishments, and campus dining facilities. Researchers, staff, and contractors rely on compressed gas cylinders to store and utilize various types of gases.

Type 1 CNG Cylinder

Type 1 CNG Cylinders, manufactured and exported from China, adhere to the ISO11439 CNG-1 standard for compressed gas cylinders. These cylinders can store natural gas under pressures of 20MPa or 25MPa and are constructed from 4130X seamless steel tubes, possessing approvals such as ISO9809-1, ISO9809-3, EN, and DOT. It’s important to note that CNG gas cylinders are explosive pressure vessels containing flammable and combustible gases, with the storage pressure for automotive cylinders typically set at 20MPa.

CNG cylinders are categorized into four types. The first category consists of seamless alloy steel cylinders (CNG-1). CNG-2 refers to composite gas cylinders with steel or aluminium lining and a barrel reinforced with long fibres impregnated with “hoop winding” resin. The third category encompasses composite gas cylinders with an aluminium liner, carbon fibre thoroughly wound, and glass fibre ring wound reinforcement (CNG-3). Finally, the fourth category comprises composite gas cylinders with a plastic liner, carbon fibre full winding, and glass fibre 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 cylinder typically includes a cap, a valve, and a safety relief device. The cap protects the valve, while the safety relief device on the valve employs a rupture disc-fusible plug combination for enhanced safety measures.
