Compressed Gas Cylinder

Compressed Gas Cylinder

DSW Industry offers high- and low-pressure compressed gas cylinders for a safe and reliable gas supply.
Science and engineering buildings, machine shops, retail stores, and campus dining regularly use compressed gas cylinders.
Researchers, staff, and contractors store and use various compressed gases for different reasons.
We store many compressed gases under extremely high pressures, up to 2,500 PSIG (pounds per square inch gauge).

Compressed Gas:
Compressed gas is a term used to describe compressed gases stored in cylinders.
Compressed gas pressure is much higher than that of the surrounding air.
Liquefied, non-liquefied, and dissolved are the three main compressed gas types.

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 vapour pressure greater than 276 kPa (40 psi) at 38 degrees Celsius

Features

Pressure Resistance: Industrial gases such as oxygen, nitrogen, argon, and carbon dioxide are often stored in compressed gas bottles. The pressure in these cylinders can range from 200 to 3000 psi (pounds per square inch) or approximately 14 to 207 bar.
Strength and Durability: Compressed gas cylinders are typically made from durable materials such as steel or aluminium alloy. These materials provide strength and structural integrity to withstand the forces exerted by the high-pressure gases.
Valve System: Each compressed gas cylinder is outfitted with a valve system that allows for controlled release or regulation of the gas flow.
Pressure Devices: Compressed gas bottles often include pressure relief devices, such as burst discs or valves, to prevent overpressurization. These safety mechanisms release excess pressure if it exceeds the maximum allowable limit.
Transportability: Compressed gas bottles are designed to be portable and easy to transport.
Gas Compatibility: Compressed gas cylinders are manufactured to be compatible with specific gases or gas mixtures.
Size Range: These sizes range from small portable bottles used for welding or medical applications to large cylinders used in industrial processes or gas distribution.

Compressed Gas Bottles, which can store compressed gas under pressure of 20 MPa or 25 MPa, are made of 4130X seamless steel tubes with ISO9809-1/ISO9809-3/EN/DOT approval.
These bottles are classified as explosive pressure vessels because they contain flammable and explosive gases.
The storage pressure for automotive cylinders is 20 MPa.

Industrial Applications

Compressed cylinders have a wide range of applications across various industries. Here are some key areas where they find use:
Welding and Cutting: Gases like oxygen, acetylene, and propane are essential for various welding and cutting processes. These gases are stored and delivered in compressed cylinders.
Metal Fabrication: Inert gases like argon and nitrogen create oxygen-free brazing, soldering, and heat treatment environments. These gases are supplied through compressed gas cylinders.
Chemical Processing: Many chemical reactions require specific gaseous environments. Compressed gas cylinders, such as hydrogen, nitrogen, and chlorine, provide a convenient source of various gases for these processes.
Food and Beverage Processing: The food and beverage industry utilizes compressed gases like carbon dioxide and nitrogen for carbonation, inerting, and modified-atmosphere packaging tasks.
Manufacturing: Compressed cylinders are used in various manufacturing processes, including:
Pneumatic tools and machinery operation (using compressed air)
Glass blowing (using oxygen)
Electronics manufacturing (using inert gases like nitrogen)
Calibration and Testing: Various fields use high-purity gases in compressed cylinders to calibrate instruments and test equipment.
