Supplier's note

  1. Technical Breakthroughs:

    • Corrugated Design: Enables ±30mm flexibility in the Pro model, reducing pipe stress by 40% compared to rigid alternatives.
    • 316L Stainless Steel: The Pro model’s material offers triple the corrosion resistance of standard 304 stainless, critical for diesel exhaust’s acidic byproducts.
    • Flange Reinforcement: Advanced and Pro models feature bolt-hole spacing optimized for heavy-duty applications, ensuring 25% stronger connections.

  2. Version Selection Guide:

    • Base Model: Ideal for standard diesel engines (e.g., light commercial vehicles) operating in moderate environments.
    • Advanced Model: Recommended for industrial machinery and high-temperature applications (e.g., mining equipment) needing enhanced durability.
    • Pro Model: Designed for extreme conditions (e.g., marine engines, power generators) where sustained high pressure (300 psi) and temperatures up to 800°C are standard.

With the Pro model’s 800°C tolerance, you can safely handle exhaust gases from high-output diesel engines. Pair its 316L stainless steel with the flange’s reinforced design to ensure zero leaks even under prolonged stress.
