Galvanized composite steel pipe for water supply and fire fighting with plastic
Plastic coated water pipes, For modified epoxy resin or polyethylene powder inside and outside coated plastic pipe.
Plastic coated water pipes, It has excellent comprehensive performance and strong corrosion resistance, the use of external temperature of -40℃ - 90 ℃. Applicable water delivery temperature is -30℃ - 80℃. The coated plastic steel pipe for water supply is superior in chemical stability and sanitary performance, and fully conforms to the safety evaluation standard of drinking water transmission and distribution equipment and protective materials.
Plastic Coated Water Pipes, Product Features
Water supply coated plastic steel tube coating surface smooth, beautiful, external light color can be optional. Due to the smooth inner wall, can prevent the breeding of microorganisms, small resistance of fluid transmission, can increase the flow, save energy, is used for all kinds of water supply and drainage engineering.
Plastic Coated Water Pipes, Scope Of Application
Mainly used for drinking water supply pipeline, and seawater, reclaimed water, chemical and petroleum, and most acid, alkali, salt, especially suitable for buried pipeline, service life of 50 years.
Plastic Coated Water Pipes, The Performance Index
1, the comprehensive strength is not less than 1.6mpa;
2, in the bending test between the coating did not fall off, fracture phenomenon;
3, in the flattening test between the coating did not fall off, fracture phenomenon;
