Crafted with unparalleled precision and utilizing the finest high-quality alkali-free glass fiber, our fire sleeve stands as a paragon of superior pipeline safety solutions. The alkali-free glass fiber is meticulously combined into strands using advanced sand mixing equipment, ensuring unmatched consistency and resilience. These strands are expertly woven into a circular tubular embryo tube, following a precise tight 8-shaped track that guarantees both the uniformity of the weave and the structural integrity. This innovative embryo tube is then seamlessly coated with premium silicone rubber via a specialized coating cylinder, before undergoing a meticulous vulcanization process in a state-of-the-art drying channel. The result is a remarkable insulation sleeve that retains its soft and elastic properties under a wide temperature range from a chilling -65℃ to a scorching 260℃. Furthermore, it exhibits extraordinary endurance, maintaining its integrity even at an intense 1600℃ for 15 to 30 seconds. Importantly, the fiberglass component continues to perform efficiently even when the silicone rubber faces the fiercest of flames. This extraordinary product finds its applications across a plethora of high-temperature environments including iron and smelting industries, maritime applications, chemical processes, and more. It is the ideal choice for safeguarding cables, fluid pipes, rolling mill cables, oil pipes, generators, electrical voltage equipment, large-scale building infrastructures, hydraulic pressure equipment, automotive harness systems, and exhaust pipes, reinforcing them against extreme conditions with unmatched reliability.
