N-HAP hot-dip coated steel pipes are a new type of anti-corrosion material produced using fluidized bed dipping technology. They feature high mechanical strength, strong pressure resistance, excellent electrical insulation, high hardness, smooth inner and outer surfaces, low friction coefficient, good flame retardancy, and very low water absorption (less than 0.003%). They also operate within a wide temperature range (40℃ to 120℃).
Due to these high-performance characteristics, N-HAP hot-dip plastic-coated steel pipes are now widely used in pipeline system construction across various sectors, including electric power, telecommunications, transportation, municipal infrastructure, mining, petroleum, and the chemical industry.
