Dual-Wall Exhausts

Marco Blue > Dual-Wall Exhausts

About The Product

Advanced Dual-Wall Exhaust Technology

A dual-wall exhaust consists of an inner pipe that carries hot exhaust gases, surrounded by an insulated air gap and a durable outer pipe. This innovative design significantly reduces the external surface temperature, mitigating fire risks from contact with flammable fluids. Engineered as a robust, integrated unit, it provides a superior and longer-lasting alternative to conventional lagging or thermal blankets, which are susceptible to damage and saturation.

Your Questions Answered

Why Choose Our Dual-Wall Exhausts?

What makes your dual-wall design superior to thermal blankets?

Unlike thermal blankets that can get torn, saturated with flammable fluids, and require frequent replacement, our dual-wall exhausts are a fully integrated, robust solution. The protective outer pipe prevents damage and contamination, ensuring consistent performance and a much longer service life.

How are your exhausts "built for endurance"?

We engineer for longevity by using thicker gauge steel than OEM standards and incorporating heavy-duty, reinforced flex bellows. This construction, combined with the protective outer pipe, provides exceptional resistance to vibration, impacts, and the harsh operational environment of a mine site.

How do these systems simplify maintenance and improve uptime?

Our dual-wall systems are a 'fit and forget' upgrade. They eliminate the need for regular inspection and replacement of fragile blankets. Because they are a direct-fit installation with no special tools required, they reduce maintenance time and complexity, directly contributing to increased machine availability.

Do dual-wall exhausts effectively reduce fire risk?

Yes, this is one of their primary benefits. The insulated air gap between the inner and outer pipes dramatically lowers the external surface temperature. This keeps the surface well below the flashpoint of common hydraulic oils and fuels, significantly reducing the risk of a fire starting from a fluid leak.
