Oil & Gas
Gas detection equipment serves as the core safeguard for safety in the oil & gas industry. It is deployed across the entire value chain—production, storage, transportation, and end-use—to monitor flammable gases (e.g., hydrocarbons, hydrogen), toxic gases (e.g., hydrogen sulfide, carbon monoxide), and oxygen concentrations, as well as volatile organic compounds (VOCs).
Fixed gas detectors are typically installed at critical points, providing real-time monitoring and triggering alarms when gas concentrations exceed safe levels. Portable and handheld devices are used during maintenance tasks, well testing, and confined space entries, ensuring personal safety in dynamic and often unpredictable conditions.
By providing real-time alerts for risks such as leaks, explosions, and poisoning, gas detection equipment ensures the safety of personnel, the stability of equipment, and compliance with environmental regulations.
Oil Industry
Oil extraction:
Gas detection equipment is essential throughout the oil extraction process, where workers face continuous risks from flammable and toxic gases. During drilling, well completion, and production operations, detectors monitor for gases such as methane, H2S, and volatile hydrocarbons that can leak from wellheads, mud systems, or production equipment.
Refinery Process Units:
Refining operations (e.g., distillation, catalytic cracking, hydrocracking) involve high-temperature, high-pressure separation and reactions, which can lead to leaks of gasoline vapors, diesel mists, and hydrogen sulfide (from sulfur-containing crude oil).
Chemical Production Plants:
Processes like ammonia synthesis, ethylene production, and styrene polymerization involve hydrogen (H₂), carbon monoxide (CO), and benzene (C₆H₆) —all highly hazardous.
Storage Tanks and Loading/Unloading Areas:
Tanks storing crude oil, refined products (gasoline, diesel), and liquefied petroleum gas (LPG) are major hazard sources. Leaks can form explosive mixtures.
Wastewater Treatment and Flare Systems:
Wastewater ponds (e.g., oil-water separators, flotation tanks) release hydrogen sulfide and methane due to anaerobic decomposition of organics, while flare gas treatment towers may leak sulfur dioxide (SO₂) and nitrogen oxides (NOₓ).

Natural Gas Industry
Natural Gas Extraction:
High-sulfur natural gas wells (with H₂S content ≥5% by volume) pose risks at wellheads,
drilling platforms, and mud circulation systems.
ENN Group’s gas infrastructure projects across China have long cooperated with Xinhaosi for both industrial and household products.
Natural Gas Pipeline Networks:
Long-distance pipelines are vulnerable to leaks at valve stations,
river/crossing sections, and cathodic protection stations
due to corrosion or third-party damage.
Natural Gas Storage Facilities:
Underground gas storage (salt caverns/depleted reservoirs) and LNG (liquefied natural gas) terminals require monitoring for methane leaks and oxygen concentrations (to prevent asphyxiation).
End-Use Terminals:
CNG/LNG Stations: Compressed natural gas (CNG) storage tanks and dispensers may leak methane; LNG storage tanks and vaporizers require monitoring for methane vapors and cryogenic risks.
Gasoline Stations: Underground storage tanks (gasoline/diesel) and dispenser piping are prone to gasoline vapor leaks.
