PU Internal Coating Application:1.Can be used for water supply projects, can also be used to transport waste water with a high content of solid particles,industrial water and surface water, and pipe installation when the tilt is large, resulting in high flow rate environment.2. PU lined ductile iron pipes in line with the requirements of the standard can transport all types of water, domestic sewage and various types of industrial waste water, ductile iron pipes can not transport less than PH1 or more than PH13 sewage. PU External Coating Application:External corrosion protection of pipelines in highly corrosive soil environment, for example:1.Through the sea, salt, marsh and other humid areas;2.Resistivity <750 ω.cm;3.Acid peat soil;4.Soil containing garbage, oxide scale, slag or contaminated by waste water or industrial waste liquid, or requiring special reinforced protective coating.Production ProcessQuality ControlTransportationTransporting:1.DN80-DN300: Usually by bundles; 2.DN350-DN2000: Usually by bulk; 3.During transportation, the pipes are fixed by timbers, blocks, nails & steel ropes with cushions at the side in possible moving directions; 4.Bulk or containers for shipment, and trucks or train for inland transport.Government AuditsCompany
