Product DescriptionHERMAL PREINSULATED DUCTILE IRON PIPEInsulation materials for prefabricated heating ductile iron pipesThe insulation construction process of prefabricated heating ductile iron pipes is divided into: pipe-in-pipe process and spray-wrap process.1. Pipe-in-pipe processUse special high-pressure injection equipment to inject the uniformly mixed polyurethane liquid raw material into the cavity between the outer protective pipe and the working pipe or pipe fittings to form an insulation structure.2. Spray-wrap processFirst, use special spray equipment to continuously spray the uniformly mixed polyurethane liquid raw material on the outer surface of the working pipe to form a continuous rigid polyurethane foam insulation layer, and then use extrusion equipment to continuously wrap the molten high-density polyethylene (HDPE) sheet on the surface of the insulation layer to form a continuous and dense HDPE outer protective layer.Ductile iron has better corrosion resistance than carbon steel. The service life of the tube is 50 years, and the service life of the steel tube is 30 years. The tube is anti-corrosive both inside and outside.Solves heat loss in district heating systems with integrated insulation that maintains consistent fluid temperatures.Combines ductile iron's strength with multi-layer protection to outperform standard pipes in harsh environments.Pre-insulated construction eliminates field-applied insulation, reducing labor costs and project timelines.Product ParametersTECHNICAL PARAMETERSProduct NameHermal Preinsulated Ductile Iron PipeKeywordsCast Iron PipeTrademarkDATONGStandardIS02531/En545/En598/GBT13295/GBT26081UsageWater Supply Project, Drainage, Sewage, Irrigation, Water Pipeline.Gas Supply, Oil PipelineMaterialsCast Iron(C, Si, Mn, P, S, Mg)PressurePN10, PN16, PN25,PN40ClassK9, K10, K12, C25, C30, C40Internal CoatingA).
