Main Features of High-Temperature Fireproof Sleeves

High-temperature fireproof sleeves are made by weaving alkali-free glass fibers or high-loose glass fibers into

a tubular shape, coated with organic high-temperature resistant red iron oxide silicone, and processed at high

temperatures. Our company has developed products specifically for protecting pipelines such as hydraulic

hoses, cables, metals, and hoses in high-temperature environments like steel plants, smelters, glass factories,

rail transit, and large substations, as well as for various harsh environments.

The main features of high-temperature fireproof sleeves are as follows:

1. Can block splashes of high-temperature melts such as molten iron, copper, and aluminum.  

2. Can block heat radiation generated by flames.  

3. Prevent burns from high-temperature pipes.  

4. Flexible and wear-resistant, moisture-proof, waterproof, oil-proof, and pollution-resistant.  

5. Prevents heat loss, which is beneficial for energy saving and reducing consumption.  

6. Strong dielectric insulation of the fireproof sleeve.  

These characteristics make it suitable for protecting hoses, cables, and pipelines in harsh environments. It can be continuously exposed to temperatures up to 550°C without damage and can withstand temperatures up to 1650°C. The destructive test at 1650°C can last for half an hour. After half an hour, the outer coating begins to carbonize, while the fiberglass remains intact.  

Due to the special nature and necessity of the steel casting industry, this industry attaches great importance to it. In daily work, it must cope with various high-temperature environments, which keeps some equipment in a constantly hazardous environment. It can supply power and electricity through cables. The normal operating temperature is far lower than the temperature of the steel in the environment, which requires the use of insulated sleeves to protect the cables.
