The Difference Between Steel And Plastic Composite Pipe And Lined Plastic Steel Pipe

1. Performance characteristics of steel plastic composite pipe: steel plastic composite pipe is referred to as steel plastic pipe, it is the steel pipe as the base material, coated with plastic material, so it not only maintains the high toughness of the steel pipe, but also has high pressure resistance, impact resistance, rupture resistance and other characteristics. Compared with the traditional galvanized pipe and cast iron pipe, it is more safe and reliable, economic and environmentally friendly. The galvanized pipe can replace the cast iron pipe. The installation mode of steel and plastic pipe is similar to that of galvanized pipe, and the operation is simple. In recent years, steel and plastic pipes have been widely used in developed cities in China. With the continuous transformation of the urban direct drinking water project, steel and plastic pipes will achieve greater market space.
2. Technical properties and characteristics of lined plastic steel pipe: one, by the surface by galvanized and baking paint double anticorrosion treatment of steel pipe and plastic pipe through diameter shrinkage, bonding and other special process composite.2. High strength; working pressure of the system is 2.0 Mpa; working temperature of cold water pipe is 0℃ ~ + 55℃, working temperature of hot water pipe is 0℃ ~ + 75℃, and line expansion coefficient is 2.510-5 / ℃.3. Clean and non-toxic, safe and hygienic, and all the performance indicators meet the requirements of "Hygienic Evaluation Code for Drinking Water Transmission and Distribution Equipment and Protection Materials".4, the inner wall is slippery, no rust corrosion, no scaling, no diameter loss.5. Using silk buckle connection, groove pipe fitting connection, flange connection, the inner surface of the pipe fitting enamel disposal, reliable installation, convenient protection. Six, from DN15- -DN300 specifications and varieties are complete. Application: building water supply and medium water system; hot water, air conditioning circulating water and heating system; fire sprinkler system; industrial water and equipment circulating water system.
A new composite pipe pipe, many places referred to as steel plastic pipe. Steel, is a kind of iron material; plastic, plastic, plastic is generally high density polyethylene (HDPE).
