Product Description Product Description The outer protective layer of the FrostGuard Thermal Pipe Insulation System is meticulously crafted from high-strength, high-toughness polyethylene material. Utilizing Shandong Donghong Pipe Industry Co., Ltd.'s revolutionary polyethylene modification technology, this layer undergoes a surface polarization process that significantly enhances its adhesive compatibility with polyurethane. This pioneering approach ensures superior adhesion performance, offering unmatched durability and efficiency in thermal insulation applications.Working Steel Pipe Diameter mmOuter Sheath Diameter mmMinimum thickness of outer sheath mm Insulation layer thickness mm426494-5544.030-60478547-6074.530-60529598-6584.530-60630700-7605.030-60720790-8505.030-60820891-9515.530-60920992-10526.030-6010201093-11536.530-6011201194-12547.030-6012201316-14368.040-10014201538-16789.050-12016201760-188010.060-12018201960-208010.060-120Note: can be customized as customer's needs. Our Advantages 1. Working Steel Pipe: Constructed from high-quality seamless steel pipe, spiral welded pipe, and straight seam welded pipe. Before thermal insulation application, our pipes undergo rigorous mechanical rust removal, ensuring they meet or exceed the exacting GB/T8923.1 Sa level 2.5 standard.2. Slepipe: Designed with a unique blend of flame retardant and anti-static polyethylene resin, expertly processed using a single screw extrusion machine. This engineering marvel provides our pipes with unparalleled impact resistance, superior isolation capabilities, and formidable corrosion resistance.3. Polyurethane Insulation Layer: We employ advanced modified flame retardant polyurethane foam, meticulously injected under high pressure to fill the void between the casing and the working steel pipe. This innovative approach delivers exceptional insulation, featuring low thermal conductivity, high compression strength, minimal water absorption, and a remarkable closure rate. 1. Eliminates the necessity for support structures, dramatically reduces heat loss, and completely eradicates the 'support thermal bridge' phenomenon.2. Offers exceptional strength and remarkable toughness, with easy welding capabilities and convenient construction processes.3. Demonstrates exceptionally low thermal conductivity alongside robust waterproof and corrosion-resistant properties, making it ideal for direct burial either underground or underwater.4. Ensures seamless connectivity through flange or quick joint connections, facilitating hassle-free installation.5. Boasts an impressive service lifespan, reliably performing in environments ranging from -20oC to 120oC for over three decades.Connection Method Explore Versatile Connection Methods for Maximum Flexibility Flange connectionFlexible socket connection Step-by-Step Welding Joint Demonstration for Precision and ReliabilityAppliation Cases Insulation steel pipes are indispensable in liquid and gas transmission pipe insulation projects across various sectors such as petroleum, chemical industries, central heating systems, heating networks, central air-conditioning ventilation pipes, and municipal engineering. Our high-temperature prefabricated direct-buried thermal insulation steel pipe stands out as a premier choice, offering exceptional thermal insulation performance, unparalleled safety and reliability, and notably reduced construction costs.
