Product Description

Product Description

 
This safety pressure relief device is designed specifically for high-pressure gas cylinder systems in tube trailers. It provides overpressure protection during transportation and is suitable for gases such as hydrogen, natural gas, helium, and nitrogen. Its compact design, rapid response, high reliability, and durability comply with multiple international transportation safety standards.

Product Highlights:

1.Compact size and structure with minimal space constraints.
2.Highly responsive; activates pressure relief instantly during abnormal pressure surges to prevent cylinder explosions or
structural damage.
3. Metal-to-metal high-sealing structure effectively prevents leakage.

Product Features:

1.High-pressure-resistant design tailored for gas transportation, ensuring stable and reliable long-term operation.
2.Made of high-performance materials with excellent corrosion resistance for harsh transport environments.
3. Compact size allows easy integration into valve clusters, control panels, or pipeline interfaces, supporting both standard and customized configurations.
 

Application

 

1.Industrial Gas Transportation:
CNG tube trailers: Prevents pipeline overpressure caused by temperature fluctuations or accidents.
Hydrogen transport trailers: Ensures safety of high-pressure hydrogen pipeline systems.
2.Energy Refueling Scenarios:
CNG fueling stations: Acts as a safety isolation device between trailers and station pipelines during gas unloading.
Hydrogen refueling stations: Provides overpressure protection during high-pressure hydrogen unloading.
3.Chemical Industry:
Electronic specialty gas transport (e.g., silane, phosphine): Dual-layer protection against toxic gas leaks.
CO₂ transport: Addresses pressure anomalies caused by dry ice phase changes.

 

Our Advantages

Our company is a science & technology-oriented enterprise specializing in rupture disk safety devices, rooted in Chinese aerospace engineering technology. The development of our first rupture disk for aerospace applications began in 1959. In 1981, this specialized technology was successfully adapted for civilian use, resolving long-standing domestic production challenges of industrial safety devices across multiple sectors in China. In 1986, the company obtained the Manufacturing License for Rupture Disk Devices issued by the Ministry of Labor. In 2000, it was certified as a high-tech enterprise by the Science & Technology Department of Liaoning Province.
