Anti-corrosion spiral steel pipes for water supply and drainage
Anti-corrosion spiral steel pipes designed for water supply and drainage feature a layer of polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, and non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC) on the inner wall, with a thickness ranging from 0.5 to 1.0 mm. These plastic-coated steel pipes combine the strength, ease of connection, and resistance to water flow impact of traditional steel pipes with the corrosion resistance, cleanliness, and lack of scaling of plastic pipes. Additionally, they offer better strength and fire resistance compared to purely plastic pipes, with a design life of up to 50 years.
