ISO 9809 Seamless Steel Oxygen Gas Cylinder
The Oxygen Cylinder with CGA540 valve is a high-pressure seamless steel gas cylinder designed for
medical, industrial, and specialty oxygen applications. Manufactured in accordance with
ISO 9809, this cylinder offers excellent mechanical strength, pressure stability, and long-term safety
for oxygen storage and transportation.
Equipped with the internationally recognised CGA 540 valve connection, it ensures secure gas regulation,
reliable sealing, and compatibility with standard oxygen regulators used in North America and global markets.
Product Overview
Reliable Oxygen Storage for Medical and Industrial Use
This CGA540 oxygen cylinder is engineered to meet the demanding requirements of
hospitals, laboratories, welding facilities, industrial plants, and gas filling stations.
The seamless steel construction eliminates welded joints, significantly reducing leakage risk and improving safety
under high-pressure operation.
With multiple size options ranging from small portable cylinders to large industrial formats, it supports flexible
deployment across a wide range of oxygen supply systems.
CGA 540 Valve – Secure and Standardised Oxygen Connection
Designed for Safety and Precise Gas Control
The CGA 540 valve is a critical safety component specifically designed for oxygen service.
It provides a robust mechanical connection between the cylinder and regulator, preventing incorrect gas connections
and ensuring stable oxygen flow.
- Secure and leak-resistant sealing
- Compatible with standard oxygen regulators
- Reduces risk of incorrect gas connection
- Suitable for high-pressure oxygen applications
ISO 9809 Seamless Steel Cylinder Construction
High-Strength Materials for Long Service Life
The cylinder body is manufactured using high-quality seamless alloy steel,
offering excellent resistance to internal pressure, mechanical impact, and fatigue caused by repeated filling cycles.
- 34CrMo4
- 30CrMo
- 37Mn
Each cylinder undergoes strict inspection and pressure testing to ensure full compliance with international safety
standards.
