Guardian of Industrial Long-Distance Monitoring: OFSCN® 300°C SST High-Temperature Optical Fiber Cable

Across kilometers of oil and gas pipelines, within exploration wells thousands of meters deep, or inside high-temperature chemical transport systems, traditional point-type sensors have long reached their limits. How can we achieve real-time, zero-blind-spot monitoring across entire spans? How can we ensure data stability for years under the dual challenges of intense heat and corrosion?

The OFSCN® 300°C SST seamless stainless steel tube high-temperature optical fiber cable, developed by Beijing Dacheng Yongsheng Technology Co., Ltd., is the irreplaceable "Guardian" of long-distance industrial monitoring, thanks to its exceptional compatibility with distributed sensing.

1. Eliminating "Blind Spots": The Advantage of Distributed Sensing

Traditional sensors are placed at intervals, leaving the gaps between them as "blind spots" for potential safety hazards.

• Full-Line Sensing in One Cable: The OFSCN® 300°C SST cable turns every centimeter of fiber into a sensing point. When paired with a DTS (Distributed Temperature Sensing) system, it provides real-time feedback on temperature at thousands of locations across the entire line.
• Instant Response: Whether it is a temperature change caused by a minor pipeline leak or an abnormal vibration impact, the distributed system can pinpoint the fault location with meter-level precision within seconds.

2. Core Advantages: Why It Stands Guard Over the "Lifeline"?

As a core unit for long-distance monitoring, the 300°C SST cable is specifically reinforced for extreme operating conditions:

A. Superior Hydrogen Shielding and Anti-Hydrogen Darkening Technology

In environments reaching 300°C, hydrogen ingress is the primary enemy of optical fibers. Once hydrogen enters the fiber core, it causes rapid signal attenuation (darkening), rendering the monitoring system useless.

• Physical Barrier: Utilizing 316L seamless stainless steel tubes with longitudinal laser welding creates a 100% hermetic physical barrier.
• Extended Lifespan: This advanced encapsulation significantly blocks hydrogen ion penetration, ensuring a long service life for monitoring systems in harsh environments.

B. High Rigidity for Vibration Sensitivity

For DAS (Distributed Acoustic Sensing) applications, the rigidity of the cable determines its sensitivity.

• Metallic Conduction: The high-rigidity alloy jacket conducts even micro-vibrations from the outside directly to the internal Silicon Dioxide (SiO2) fiber core.
• Low Damping: The specialized 15-micron thin polyimide coating minimizes signal damping, allowing the system to capture subtle mechanical intrusions or fluid leak sounds from kilometers away.

C. Extreme Mechanical and Chemical Protection

• High Tensile Strength: The 3.0 mm diameter specification offers a tensile strength exceeding 1200 Newtons (N), sufficient for deep-well suspension or long-distance pull-through installations.

• Corrosion Resistance Options: Beyond standard 316L, Alloy 825 jackets are available to handle high salt spray, high sulfur, or acidic corrosive environments.

3. Empowering the Future of Digital Industry

The application of OFSCN® 300°C SST cables goes beyond simple "temperature measurement"; it is building the nervous system of industrial digitalization:

• Smart Oil & Gas: Realizing full-depth production fluid profile monitoring in oil wells.
• Power Grid Safety: Monitoring temperature rise in high-voltage cable tunnels to prevent fire hazards.
• Chemical Parks: Establishing a comprehensive safety network for reaction towers and long-distance transmission pipelines.

4. Conclusion: Invisible Protection, Visible Peace of Mind

Safety monitoring has no finish line. Beijing Dacheng Yongsheng Technology Co., Ltd. is committed to providing "kilometer-level" security for global industrial infrastructure through stronger, more sensitive, and more durable fiber optic sensing technologies.
