This state-of-the-art polyurethane-foam tubing is meticulously engineered to insulate central heating and domestic-water pipelines. With an impressive temperature resistance ranging from -50°C to 135°C, it ensures exceptional protection and minimal heat transfer. The robust construction guarantees long-lasting durability and safeguards against pipe damage. Furthermore, its remarkable chemical resistance makes it ideal for diverse applications.Our cutting-edge rigid polyurethane spray polyethylene wrapped prefabricated direct-buried insulation pipe harnesses advanced technology to optimize foam density uniformity and insulation layer thickness consistency. This avant-garde design not only conserves materials but also significantly lowers labor costs, presenting a highly cost-effective solution for transporting hot water at temperatures up to 140°C.Working Steel Pipe Diameter mmOuter Sheath Diameter mmMinimum thickness of outer sheath mm Insulation layer thickness mm426494-5544.030-60478547-6074.530-60529598-6584.530-60630700-7605.030-60720790-8505.030-60820891-9515.530-60920992-10526.030-6010201093-11536.530-6011201194-12547.030-6012201316-14368.040-10014201538-16789.050-12016201760-188010.060-12018201960-208010.060-120 Note: can be customized as customer's needs. Connection Method Pipe fittings are the cornerstone of any piping system, yet they often represent the weak link in the quality of engineering projects. To safeguard the integrity and quality of our customers' projects, Shandong Donghong Pipe Industry Co., Ltd. has established a dedicated production workshop for steel and plastic pipe fittings. We specialize in designing and manufacturing a comprehensive array of matching fittings, ensuring we can provide integrated solutions tailored to meet the specific needs of both our customers and their projects.The Flexible Socket Connection Insulation Pipe Donghong Pipeline proudly presents its newly developed flexible socket connection insulation pipe. This innovative installation method is significantly faster than traditional welding connections, effectively eliminating the common defects associated with welding patches during construction. Insulation Pipe Patch DemonstrationProduct Features Core indicators such as thickness, density, thermal conductivity, closed cell rate and water absorption are uniform, ensuring exceptional overall stability. With minimal axis eccentricity and low thermal conductivity, this product boasts an excellent heat preservation effect. The online spraying of polyurethane offers high reactivity, superior bonding with the steel pipe and the outer protective layer. This insulation pipe remains stable despite temperature changes, with no delamination occurring. Featuring a flat surface for the insulation layer, minimal thickness deviation, and an extensive adjustment range. The outer protective layer employs a polyethylene winding method, ensuring a thin, uniform wall with reduced shrinkage, minimal deformation, and stress. This method significantly enhances the mechanical properties and resolves cracking issues. By reducing the thickness of the polyethylene outer protective layer, costs are saved. Under identical insulation conditions, deformation and stress on the outer layer are minimized, allowing for a significantly thinner protective layer.
