How to Protect Multi-Million Dollar Industrial Equipment in 700°C "Hellish" Temperatures?

In the modern heavy industry sector, high temperatures often go hand-in-hand with high productivity. However, they also bring significant safety risks. Steel furnaces, chemical reactors, deep-water oil and gas wells, and aerospace engines—the value of these assets is often measured in millions or even hundreds of millions of dollars. Once temperature monitoring fails, it leads not only to expensive equipment damage but also to catastrophic production accidents.

Facing the "hellish" heat of 700°C, conventional monitoring methods often fail due to material melting or signal drift. The OFSCN® 700-C-SST seamless stainless steel tube high-temperature optical fiber cable, developed by Beijing Dacheng Yongsheng Technology Co., Ltd., is specifically designed to solve this challenge.

1. The Core Pain Point: Why Do Conventional Monitoring Methods Fail?

In environments exceeding 300°C, the plastic jackets of ordinary optical cables carbonize and disappear, and the Silicon Dioxide (SiO2) structure inside the fiber becomes extremely fragile. At operating temperatures of 700°C, metal oxidation, hydrogen penetration (hydrogen darkening), and thermal stress can cause total signal interruption, leaving expensive equipment in a "blind monitoring" state.

2. 700-C-SST: The "Body Armor" for Multi-Million Dollar Assets

The OFSCN® 700-C-SST is not just an ordinary cable; it is a precision-engineered protection system. How does it achieve real-time guardianship under extreme heat?

A. Hardcore Protection with Seamless Stainless Steel Tube (SST)

The outer layer features a 316L seamless stainless steel tube. Unlike common wrapped or seamed tubes, this seamless tube is formed via longitudinal laser welding, providing 100% airtight and watertight integrity. It acts as an indestructible "skin," shielding the inner fiber from corrosive gases and moisture.

B. Specialized High-Temperature Fiber and Coating

The internal fiber is not standard communication fiber. It utilizes advanced coating technology (such as Polyimide or Metal coatings). This ensures that the Silicon Dioxide (SiO2) matrix of the fiber does not suffer performance degradation at 700°C, maintaining stable and reliable signal transmission.

C. Distributed Sensing: 360-Degree Dead-Zone-Free Monitoring

When paired with demodulation equipment, the 700-C-SST enables Distributed Temperature Sensing (DTS). This means the entire cable acts as thousands of sensors, capturing temperature changes every centimeter in real-time. If a local hotspot occurs, the system issues an alert within seconds, preventing multi-million dollar equipment from being destroyed.

3. Wide Range of Applications

Currently, the OFSCN® 700-C-SST plays a critical role in several high-value sectors:

• Oil and Gas: Monitoring high-temperature and high-pressure conditions in wells thousands of meters deep to prevent blowouts.
• Power Systems: Fire monitoring for high-voltage cable joints and cable mezzanine levels.
• Metallurgy and Chemicals: Hotspot monitoring for reactor walls and furnace linings.
• Aerospace Research: High-temperature structural testing for engines and experimental chambers.

4. Conclusion

In the face of extreme conditions, reliability is the greatest driver of productivity. The OFSCN® 700-C-SST cable from Beijing Dacheng Yongsheng Technology Co., Ltd. uses advanced material science and manufacturing processes to build a solid high-temperature firewall for your most valuable assets.
