Steel lined polyethylene pipeline/steel lined PE pipeline：

Steel lined and internally sprayed modified polyethylene (PE) steel plastic composite pipes, components, and containers are made of carbon steel pipes as the matrix. According to the different working conditions and technical requirements of users, the steel pipes are lined with chemically stable thermoplastic composite materials such as PE, and advanced hot rolling molding technology is used to melt and combine PE plastic with the steel matrix into one. Steel lined polyethylene pipes have the characteristics of low density, high strength to quality ratio, low brittleness temperature, good toughness, good corrosion resistance and insulation performance, easy coloring, and easy construction and installation. Specially designed for corrosive media containing chloride ions, it has unique properties and is an excellent anti-corrosion material.

Performance characteristics of steel lined polyethylene pipes/steel lined PE pipes：
1. Superior acid, alkali, salt and some organic solvents resistance
2. Superior insulation and resistance to electrochemical corrosion
3. Working under the condition of negative pressure and vacuum degree of 72mmHg
4. Smooth surface with low friction coefficient, excellent resistance to foreign objects and wear

Steel lined polyethylene pipes/Steel lined PE pipes are mainly used in municipal and building water supply and drainage, gas, heating, wire and cable threading, agricultural water-saving irrigation and industrial sewage, mining mineral transportation and other fields.
In developed countries and regions abroad, steel lined PE pipelines account for over 90% of intercity buried gas pipelines and 60% of the market share in water supply pipelines. Moreover, mature construction standards have been established for steel lined PE pipelines abroad. After the gradual ban of galvanized pipes in China, steel lined PE pipelines have a competitive advantage in areas such as building water supply, and are also rapidly growing in fields such as gas, industrial water supply and drainage, communication, and agricultural irrigation.
