Compressed Gas Cylinder
DSW Industry offers a variety of high and low pressure Compressed gas cylinders for a safe and reliable gas supply.
Compressed gas cylinders are used regularly in science and engineering buildings, machine shops, and retail and campus dining.
Researchers, staff, and contractors store and use various compressed gases for different reasons.
Many compressed gases are stored under extremely high pressures. (Up to 2,500 PSIG or pounds per square inch gauge).
The sudden release of gases from a cylinder can transform it into a projectile capable of penetrating concrete block walls.
When handled correctly, compressed gas bottles pose no danger. However, if mishandled, they can be a severe hazard to you and the area around you.
Gas cylinders are equipped with a valve that controls the gas release. A cap, collar, or neck ring protects the valve assembly when the gas isn’t used. When dispensing from a gas bottle, a pressure regulator assembly controls the gas flow at the desired level.
Compressed Gas: A material in a container with an absolute pressure greater than 276 kilopascals (kPa), or 40 psi (pounds per
square inch) at 21 degrees Celsius or a total pressure greater than 717 kPa (104 psi) at 54 degrees Celsius, or both, or any liquid
flammable material having a Reid vapor pressure greater than 276 kPa (40 psi) at 38 degrees Celsius

Compressed Gas Bottles, 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 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 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 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.
