Defying High-Temperature Meltdown: How 200℃ SST Seamless Stainless Steel Tube Optical Fiber Cables Conquer Energy Industry "Extreme Forbidden Zones"?

In fields such as energy exploration, power transmission, and heavy industrial manufacturing, there exist "forbidden zones" for standard equipment. These environments are not only subjected to continuous high temperatures exceeding 150℃ but are also filled with high pressure, corrosive liquids, and massive mechanical stress. Traditional polymer-jacketed optical cables often fail instantly in these areas—jackets melt, signal loss spikes due to hydrogen darkening, and mechanical integrity collapses.

To break this deadlock, Beijing Dacheng Yongsheng Technology Co., Ltd. (OFSCN®) has developed the 200℃ SST Seamless Stainless Steel Tube Optical Fiber Cable (Fiber In Metal Tube, FIMT). It is more than just a cable; it is the "steel neural system" for the energy industry’s transition to intelligent monitoring.

1. The "Achilles' Heel" of Conventional Optical Cables

In oil drilling, shale gas extraction, or high-voltage substations, standard cables face three fatal threats:

1. Thermal Degradation: Common Polyethylene (PE) or Polyvinyl Chloride (PVC) jackets start softening above 80℃ and completely melt or decompose beyond 150℃.
2. Hydrogen Darkening: In high-temperature oil and gas environments, hydrogen molecules penetrate the fiber core and react with Silicon Dioxide (SiO2), causing a sharp increase in optical loss and total communication failure.
3. Mechanical Damage: Lateral pressure from deep geological layers and tension during installation can easily snap fragile glass fibers.

2. The Core "Black Technology" of 200℃ SST Cables

The 200℃ SST cable developed by OFSCN® addresses these challenges through structural re-engineering and material innovation.

A. Seamless Stainless Steel Welding Technology (The Seamless Shield)

Unlike common interlocked armor or seamed tubes on the market, this product utilizes high-precision seamless stainless steel long tubes. This metal shell acts as an impenetrable barrier, achieving 100% airtightness. It not only physically isolates moisture and corrosive gases but also effectively blocks the penetration of hydrogen molecules, ensuring the long-term lifespan of the internal fibers.

B. Special High-Temperature Fiber and Coating

The internal fibers are not standard commercial products. They feature special high-temperature resistant treatments. Combined with Polyimide coating materials, the cable can operate stably in environments of 200℃ for long periods, with even higher instantaneous temperature tolerance.

C. Ultra-Small Diameter and High Strength

Despite its stainless steel shell, the outer diameter is typically only 1.0mm to 3.0mm. This "thin as a hair, strong as steel" characteristic allows it to easily pass through the gaps in oil pipes or be embedded within the windings of large power transformers.

3. Conquering the "Forbidden Zones": Typical Applications

• Downhole Oil & Gas Monitoring: In wells thousands of meters deep, the 200℃ SST cable acts as a carrier for Distributed Temperature Sensing (DTS), providing real-time feedback on temperature and pressure changes to help engineers optimize recovery rates.
• Power Cable Temperature Measurement: In urban high-voltage cable tunnels, monitoring joint overheating is critical for fire prevention. This cable is corrosion-resistant and immune to electromagnetic interference, making it the optimal choice for high-voltage environments.
• Industrial Furnace Monitoring: On the outer walls of metallurgical or chemical furnaces, SST cables resist sparks and radiant heat, ensuring real-time upload of critical monitoring data.
