What Does Burst Pressure Mean?
Burst pressure is the pressure level where a cartridge will rupture. A higher burst pressure means a larger safety margin during storage and use.
Why Is Wall Thickness Important for CO2 Cartridges?
Wall thickness affects strength, pressure resistance, and safety. Larger CO2 cartridges usually require thicker walls to handle higher gas volume and pressure.
Why Do Different Cartridges Use Different Neck Types?
Different neck sizes are designed for different applications and puncture systems. This helps ensure proper sealing, compatibility, and safe gas release.
Why Are 45g and 74g Cartridges Threaded?
45g and 74g cartridges use threaded necks because larger cartridges need a more secure connection to handle higher gas volume and stronger operating pressure.
Manufacturing & Quality Control
Manufacturing Process
- Deep drawing forming
- Resistance pinch welding
- Zinc plated surface treatment
- 100% leak testing
- Hydrostatic pressure testing
- Gas purity control
Quality Assurance
Every cartridge is manufactured under strict production and inspection standards to ensure stable pressure performance, sealing reliability, and export-grade quality consistency.
FAQs
What Is the Standard Pressure of a 12g CO2 Cartridge?
A standard 12g CO2 cartridge typically operates at around 800–1000 psi at room temperature.
Are 74g CO2 Cartridges Threaded?
Yes. Most 74g CO2 cartridges use threaded necks for secure installation and safe high-pressure connection.
What Steel Material Is Used for CO2 Cartridges?
Most steel CO2 cartridges are made from deep drawing carbon steel such as EN10139 DC04 for strength and pressure resistance.
What Applications Use 33g and 45g CO2 Cartridges?
33g and 45g CO2 cartridges are commonly used for inflatable life jackets, marine safety equipment, and industrial inflator systems.
Why Is Burst Pressure Important for CO2 Cartridges?
Burst pressure shows the maximum pressure a cartridge can withstand before rupture. Higher burst pressure means better safety margins.
What Is the Difference Between Threaded and Non-Threaded CO2 Cartridges?
Threaded cartridges provide a more secure connection for larger or high-pressure applications, while non-threaded cartridges are common in smaller disposable systems.
Why Do Larger CO2 Cartridges Require Thicker Walls?
Larger cartridges contain more compressed gas, so thicker walls are needed to maintain strength, pressure stability, and safety.
