Fire Sleeves | High-Temperature Protection for Industrial Hoses and Cables

Fire Sleeves

Why Choose Our Fire Sleeves?

Fire sleeves are durable, flexible sheaths designed to protect fuel, oil, and hydraulic lines from heat damage. Manufactured from silica glass and fibre braided tubing, coated with silicone rubber and infused with iron oxide, our sleeves withstand temperatures up to 1200°C. This innovative solution not only insulates and shields hoses but also prevents flammable or corrosive fluids from spraying onto critical lines.

Benefits

Long-Term Effectiveness
Designed to continuously operate at temperatures exceeding 260°C, our fire sleeves provide reliable, long-term protection.
High-Temperature Protection
Withstands temperatures above 1000°C for up to 20 minutes, ensuring safety in extreme conditions.
Maintenance-Free
Once fitted, our fire sleeves are built to last the life of the engine, requiring minimal maintenance similar to standard exhaust systems.
Non-Flammable
Direct exposure to flames doesn’t burn the material; instead, it forms a protective silicon dioxide crust.
Easy to Install
The flexible design fits easily over hoses and cables and can extend to cover couplings and fittings, simplifying the installation process.

Thermal Assessment Capabilities

In Q1 2022 a North American Gold Mine had a fire event on site. To mitigate the risks of fires from occurring, the site’s mobile maintenance team engaged Mammoth to carry out thermal audits across their Load, Haul and Ancillary fleet.
The deliverables included; identifying potential fire risks and recommending controls to reduce touch surface temperatures below the flash point of flammable fluids.

Sound Attenuation

Komatsu 930E grid box and exhaust attenuation

The client operated an open cut coal mine in NSW. The sound power target for its fleet of Komatsu 930E trucks was set at 120 dB(A) to meet the boundary noise requirements. The current noise level was recorded at 124 dB(A), 4 dB(A) louder than the prescribed limits.

Sound Attenuation

Hitachi EH5000 Sound Suppressed Exhaust System

A site running Hitachi EH5000 trucks that were fitted with standard sound suppression mufflers was having issues with them due to high back pressure, cracking and falling apart prematurely. The current mufflers were not meeting the sound reduction requirements the site was seeking to achieve. The client was exceeding boundary noise limits due to upscaling of fleet size and required noise reduction to be achieved on existing trucks to continue mining at night.
