Plastic pipe corrosion Features: ☆ good anti-corrosion steel-plastic liquid pipeline corrosion and metal body is fully effective isolation, only contact with the polyolefin or PTFE coating, with good anti-corrosion effect, extend the life of the pipeline . ☆ excellent mechanical strength of steel-plastic pipe and galvanized steel pipe corrosion has the same excellent mechanical strength, impact, bending, pressure and intensity of a strong endurance. ☆ good hygiene performance ???? Plastic pipe corrosion coating of food-grade plastic or polyethylene epoxy powder form, non-toxic, odorless, cited health indicators in line with national standards of living water pipeline. ☆ fluid resistance is small? Plastic corrosion pipe wall is smooth, friction coefficient, flow speed, easy accumulation of scale, small fluid resistance. Fully lined flanged double eccentric butterfly w
