Haotian Brand HighTemperature Sleeve Features and Applications
1.Safe and Environmentally Friendly, Protects Workers' Health
Alkali-free fiberglass has strong tensile strength, does not wrinkle or break, is resistant to vulcanization, smoke-free, halogen-free, non-toxic, non-flammable in pure oxygen, and has good insulation properties. After curing with organic silicone rubber, its safety and environmental performance is further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which pose great harm to human health and the environment.
2.Excellent High-Temperature Resistance
The surface organic silicone structure of the high-temperature sleeve contains both 'organic groups' and 'inorganic structures'. This special composition and molecular structure allow it to combine the properties of organic materials with the functions of inorganic materials. Compared to other polymer materials, its standout feature is its high-temperature resistance. With a main chain structure based on silicon-oxygen (Si－O), the bond energy of C-C bonds is 82.6 kcal/mole, while the bond energy of Si-O bonds in organosilicone is 121 kcal/mole, thus it has high thermal stability. Under high temperatures (or radiation exposure), the chemical bonds of the molecules do not break or decompose. Organosilicone can withstand high temperatures as well as low temperatures, usable over a wide temperature range. Both its chemical and physical mechanical properties change little with temperature.
3.Anti-Splash, Multiple Protection
In the smelting industry, the medium temperature inside electric furnaces is extremely high, easily causing high-temperature splashes (the same is true in the welding industry). After cooling and solidifying, these splashes can form slag on pipes or cables, causing the outer rubber layer of the pipes or cables to harden and eventually become brittle and crack. This can damage unprotected equipment and cables. The high-temperature sleeve coated with multiple layers of silicone can achieve multiple safety protections, with a high-temperature resistance of up to 1300 degrees Celsius, effectively blocking splashes of high-temperature molten materials such as molten iron, molten copper, and molten aluminum, preventing damage to surrounding cables and equipment.
4.Insulation and Heat Preservation, Energy Saving and Consumption Reduction, Radiation Resistance
In high-temperature workshops, many pipes, valves, or equipment have very high internal temperatures. Without protective materials, this can easily lead to personnel burns or heat loss. Haotian's high-temperature sleeve has better thermal stability than other polymer materials, as well as radiation resistance and insulation properties, preventing accidents, reducing energy consumption, and preventing the heat of the medium inside the pipes from being transferred directly to the surrounding environment, which could excessively raise the workshop temperature and save cooling costs.
5.Moisture-Proof, Oil-Proof, Weather Aging Resistant, Pollution Resistant, Extends Equipment Lifespan
The high-temperature sleeve has strong chemical stability, being unreactive to oils, water, acids, and alkalis in organosilicone. It can be used long-term without aging within 260℃; its lifespan in natural environments can reach several decades, greatly protecting pipes, cables, and equipment in such conditions and significantly extending their service life.
6.Ozone Resistant, Voltage Resistant, Arc Resistant, Corona Resistant
Because the surface is coated with organosilicone, whose main chain is -Si－O－, it is not easily decomposed by ultraviolet light and ozone. The high-temperature sleeve has excellent electrical insulation properties, with its dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity ranking among the best in insulating materials, and their electrical performance is minimally affected by temperature and frequency. Therefore, they are a stable electrical insulating material widely used in the electronics and electrical industries.
7.Flame Retardant, Reduces Fire Incidence and Spread Rate
If flammable or toxic media are transported within the pipes, leakage can easily lead to fires or casualties; cables often burn due to localized high temperatures. The high-temperature sleeve is made from extremely heat-resistant fiberglass weaving, with the silicone surface adding appropriate flame retardants and other special materials to give it excellent flame retardancy. Even in the event of a fire, it can prevent the spread of flames and still protect the internal pipelines intact for a long time, providing ample time for rescuing data and important information. 7 Common Usage Areas:
High-temperature areas in industries such as steel, smelting, shipbuilding, and chemical, as well as in heating area cables, fluid pipelines, rolling mill cables, oil pipes, saw cutting edge cables, generator sets, electrical voltage equipment, large buildings, hydraulic systems, automotive wiring harnesses, and exhaust pipes, etc.
