Crafted with precision, the fire sleeve's core material is the superior alkali-free glass fiber. Utilizing advanced sand mixing technology, these fibers are meticulously twisted into robust strands, then intricately woven into a seamless circular tubular form using a sophisticated 8-shaped track. This meticulous process ensures an unparalleled uniformity in weaving and a structure that's exceptionally tight and reliable. To further enhance its resilience, the tubular form is enveloped in a high-grade silicone rubber coating through an advanced coating mechanism, followed by a thorough vulcanization in the drying channel. This innovative construction allows the sleeve to retain its flexible and elastic properties across a wide temperature range, from a chilly -65℃ to a scorching 260℃, and can withstand brief exposures to temperatures as extreme as 1600℃ for 15 to 30 seconds. Remarkably, even if the silicone rubber succumbs to the heat, the fiberglass remains steadfast and operational. These remarkable sleeves are indispensable in high-temperature environments across various industries, including iron and steel production, smelting, marine applications, and chemical sectors. They are ideal for safeguarding cables, fluid pipes, rolling mill cable oil pipes, generators, electrical voltage equipment, large-scale construction projects, hydraulic systems, automotive harnesses, and exhaust pipes, ensuring unparalleled protection and performance.
