Sudden Explosion in Hebei! 2 Dead, 2 Seriously Injured!
2025-12-03
On July 29 at 10:13 a.m., Anping County of Hengshui City, Hebei Province, issued a notice stating that an explosion occurred in a street-front shop of a residential community. The accident has resulted in 2 deaths and 2 serious injuries so far. Preliminary investigation shows the explosion was caused by a natural gas pipeline being pierced during the secondary water supply network renovation construction by the water supply company.
As an underground "lifeline" of the city, gas pipelines are a crucial part of urban infrastructure. Online monitoring and early warning of gas pipeline leaks can prevent accidents caused by unprompted micro-leaks. Hanhai Optoelectronics' Passive Optical Fiber Laser Leak Monitoring System enables real-time monitoring of gas leaks in gas pipelines. The monitoring site requires no power supply and can be buried underground simultaneously with the gas pipeline.
Passive Optical Fiber Laser Leak Monitoring System
Preventive Monitoring
Each monitoring channel has a response time of only 10 seconds and a transmission distance of up to 20 kilometers. It can accurately detect trace gas leaks at the ppm level, truly realizing preventive monitoring of gas leaks.
No On-Site Power Supply, Safer System
The monitoring site requires no power supply and is connected via optical fiber. The monitoring platform receives and processes information from each optical sensing terminal on-site in real-time, ensuring more stable monitoring.
Easy Installation, Flexible Configuration
It subverts the traditional system composition mode and adopts a digital design from optical sensing terminals to control systems. The simplified system structure makes installation easier and can meet more application needs of customers.
No Need to Replace Detection Components
The optical sensing terminal is a pure optical device with no loss characteristics. It has high reliability and requires no calibration.
Perfect Replacement for Traditional Catalytic Combustion Alarm Systems
It features an ultra-long overall system service life, significantly reducing the equipment operation cost throughout the life cycle—achieving a permanent solution with one installation.
Diversified Gas Detection Capabilities
It can detect gases such as methane, ethylene, acetylene (custom gas detection solutions can be provided according to customer needs).
