1. Understanding Fireproof Sleeve

Fireproof sleeve is generally used to protect industrial pipelines from high temperature, steam, heat radiation, splashing materials, spray, and sparks. They are made of fluffy glass fiber coated with silicone rubber that is resistant to fire, and can be widely applied in metallurgy, petrochemical, electric power, coal, chemical, military, aerospace, and shipbuilding industries to protect cables and pipelines. Fireproof sleeve has excellent characteristics of heat insulation, constant temperature, waterproof, fire resistance, splashing resistance, flame retardancy, and blocking of molten materials. It can sustainably operate at a high temperature of 260℃ without damage, and have an instant temperature resistance of up to 1650℃. The good weather resistance and heat insulation performance of silicone rubber can better protect the workers from burns and block heat loss, thus saving energy and reducing consumption in high temperature areas.

2. What are the main features of Fireproof Sleeve?

Fireproof sleeve is woven into tubes by alkali-free glass fiber or high fluffy glass fiber, and then coated with organic high-temperature oxidation-resistant iron red silicone rubber, which is processed at a high temperature. It can also be used to protect hydraulic hoses, cables, metals, hoses, and various pipeline circuits in high temperature environments and harsh environments such as steel plants, smelters, glass plants, rail transit, and large transformer stations. The main features of firepsleeve are as follows:

(1) Can prevent high-temperature molten materials such as molten iron, copper, and aluminum from splashing;

(2) Can block the heat radiation generated by flames;

(3) Prevent workers from being burned by high temperature pipelines;

(4) Flexible, wear-resistant, moisture-proof, waterproof, oil-resistant, and anti-pollution;

(5) Block heat loss, which is conducive to energy saving and consumption reduction;

(6) Strong dielectric insulation of fireproof sleeves. These characteristics make them applicable to protecting hoses, cables, and pipelines in harsh environments. They can sustain continuous exposure to a high temperature of 550℃ without damage and can withstand a high temperature of 1650℃. The destructive test at 1650℃ can last for half an hour, after which the outer coating begins to carbonize, but the glass fiber remains intact.

Due to the particularity and necessity of the steel casting industry, the level of attention in the industry is high, and various high-temperature environments must be dealt with in daily work. This puts some equipment in a dangerous environment. Many industries are now powered by electricity, and power can only be transmitted through cables. Normal working temperature is far lower than the steel temperature in the environment. This requires insulation sleeves to protect the cables, and fireproof sleeve is the best choice.
