Core Engineering Advantages

✅ Extreme Temp Mastery

Operates seamlessly from -45°C to +300°C (Peak 2hrs)

✅ Toxic Fume Containment

3-layer barrier: Fiberglass core + Oxford cloth 

✅ Mechanical Dominance

Spiral steel wire prevents collapse under 38kPa negative pressure

1. Gas heater exhaust system for oil and gas drilling platforms

Designed for heating flex duct, this extreme working condition solution solves the problem of exhaust gas transportation for diesel/gas indirect combustion heater in -45℃ extreme cold environment. Its double-layer spiral steel wire structure can withstand negative pressure fluctuations, perfectly matching the explosion-proof standard, while blocking the penetration of hydrogen sulfide corrosive media.

2. Acid mist and VOCs extraction system for chemical plants

As the benchmark application of flex heat duct in corrosive scenarios, it is especially suitable for reactor pressure relief, solvent recovery and other scenarios where xylene/acetone vapor exists.

3. Metal casting workshop high temperature dust collection

When welding fume and 300℃ metal sparks exist at the same time, this flexible heat duct shows unique advantages:

Instantaneous temperature resistance of 300°C

Dual-layer wire mesh resists abrasion from metal shavings
