Product advantag
Low-Temperature and Corrosion-Resistant: Made of specialized low-temperature-resistant materials, it resists brittle cracking when spraying liquid CO₂ at -78.5°C. It's also chemically resistant and suitable for use in a variety of environments, including humid and chemical environments.
High-Pressure Safe: Operating pressure reaches 15MPa, burst pressure exceeds 30MPa, and pulse fatigue testing has been passed to eliminate the risk of high-pressure leaks and ensure operational safety.
Flexible and Precise Spraying: The hose is available in optional lengths (0.5-2m) and features a small bend radius, allowing it to penetrate tight spaces. When paired with a directional nozzle, it extinguishes fires directly at the core.
Lightweight and Easy to Maintain: 40% lighter than traditional metal hoses, the hose features a smooth, easy-to-clean surface with no wrinkles or dust accumulation. Its service life is over 8 years, reducing replacement frequency.
FAQ:
Q: Has the hose's low-temperature resistance been tested? Will it crack if continuously sprayed at -78.5°C?
A: It has passed extreme low-temperature testing. After continuous spraying of liquid CO₂ at -78.5°C for 30 minutes, the hose showed no signs of embrittlement or cracking, meeting the GB 4351.1-2005 low-temperature resistance standard.
Q: Is the 15MPa working pressure compatible with all commercially available CO2 fire extinguishers? Is there a burst pressure test report?
A: It is compatible with 10-40L CO2 fire extinguishers (mainstream working pressure 12-15MPa). The burst pressure has been measured at 32MPa, and a third-party pressure test report is available, far exceeding the safety threshold.
Q: What is the hose's specific bending radius? Can it fit into narrow spaces such as equipment gaps? A: The minimum bending radius is ≤10cm, allowing it to easily bypass equipment corners. When paired with a directional nozzle, it can penetrate gaps of at least 5cm, meeting the precise firefighting needs of precision instruments, distribution cabinets, and other applications.
