Oxygen Cylinder

oxygen cylinder

An oxygen cylinder is a high-pressure container used for storing and transporting oxygen, widely used in medical, industrial, diving, aerospace, and firefighting fields. With its portability, reliability, and safety, it is a crucial device for providing oxygen support.

Working Principle

An oxygen cylinder stores oxygen under high pressure, and when in use, the oxygen release is controlled by a valve. Oxygen cylinders are usually made of high-strength materials that can withstand high pressure, ensuring the safe storage and stable supply of oxygen during transport and use.

Structural Components

The main components of an oxygen cylinder include:

  • Cylinder Body: The container for storing high-pressure oxygen, usually made of seamless steel or aluminum alloy, providing high strength and corrosion resistance.
  • Valve: Installed at the neck of the cylinder to control the release of oxygen, commonly includes needle valves and ball valves.
  • Regulator: Attached to the valve, it reduces the high-pressure oxygen to a usable lower pressure, ensuring safe usage.
  • Safety Devices: Includes burst discs and safety valves to prevent explosion due to overpressure.
  • Pressure Gauge: Displays the pressure inside the oxygen cylinder, helping to monitor the oxygen storage status.
  • Protective Cap: Protects the valve and regulator from external impacts, enhancing the safety of the oxygen cylinder.


  • High Portability: Compact design makes the oxygen cylinder easy to carry and move, suitable for various settings.
  • High Reliability: Made with high-strength materials and strict manufacturing processes, ensuring durability and safety.
  • Wide Applications: Suitable for medical aid, industrial cutting, diving, aerospace, and more.
  • High Safety: Equipped with multiple safety devices to prevent leaks and explosions, ensuring safe use.

Application Scenarios

Oxygen cylinders are widely used in the following scenarios:

  • Medical Aid: Used in hospitals and ambulances to provide oxygen support for patients with breathing difficulties, improving treatment outcomes.
  • Industrial Cutting and Welding: Supplies oxygen for metal cutting and welding processes, enhancing work efficiency.
  • Diving: Provides breathing oxygen for divers underwater, ensuring diving safety.
  • Aerospace: Supplies oxygen in aircraft and spacecraft, supporting the life support systems of pilots and astronauts.
  • Firefighting and Rescue: Provides breathing support in fire scenes, protecting the safety of firefighters.

Purchasing Guide

When purchasing an oxygen cylinder, consider the following points:

  • Material and Quality: Choose cylinders made of high-strength, corrosion-resistant materials to ensure durability and safety.
  • Capacity and Pressure: Select the appropriate capacity and pressure rating based on actual needs to ensure adequate oxygen supply.
  • Brand and Certification: Choose reputable brands and internationally certified products to ensure quality and safety.
  • Accessories and Attachments: Consider the quality and compatibility of accessories like valves, regulators, and safety devices.
  • After-Sales Service: Choose suppliers with good after-sales service to ensure maintenance and support during use.


To ensure the proper functioning and extend the service life of an oxygen cylinder, regular maintenance is essential:

  • Regular Inspections: Periodically inspect the cylinder body, valve, regulator, and safety devices to ensure they are intact and functional.
  • Cleaning: Keep the exterior of the cylinder clean to prevent dust and debris from affecting performance.
  • Pressure Testing: Regularly check the internal pressure of the cylinder to ensure normal oxygen storage status.
  • Replace Accessories: Periodically replace worn or damaged accessories like valves and regulators to maintain safety.
  • Storage: Store the oxygen cylinder in a cool, dry place away from heat and direct sunlight, and keep it away from flammable materials.


As a crucial device for oxygen storage and supply, oxygen cylinders play an important role in medical, industrial, diving, aerospace, and firefighting fields. Proper selection, use, and maintenance of oxygen cylinders can enhance efficiency, ensure safety, and extend the equipment's lifespan, providing reliable oxygen support across various industries.
