Long-term production and sales of water lined with plastic composite pipe, what is lined with plastic pipe? Carbon steel pipe lined in ordinary carbon steel pipe as a matrix lined with excellent chemical stability of thermoplastic composite or roto molded, it is both the mechanical properties of the steel pipe, there are plastic tube by cold drawing, corrosion resistance, ease scaling, difficult to grow microbial characteristics, transportation acid, alkali, salt corrosive gases and other media ideal pipeline. Lined with food-grade polypropylene, can be used for food, medicine and drinking water and other industries. Common plastic-lined steel pipe: the steel liner polypropylene tubes (GSF.PP) lined PVC tube steel liner (GSF.PVC) polyethylene tube steel liner the the polyolefin pipe (GSF.PO) steel liner PTFE tube lining poly pipe, (GSF.F4) Features: 1. has excellent physical 2 has excellent corrosion resistance. mechanical strength with steel pipe the same health non-toxic, no scaling, no microbial growth, to ensure the quality of fluid resistant to chemical corrosion, soil and marine life corrosion resistance, resistance to cathodic stripping 6. installation process maturity, convenient 7. good weather resistance, applicable desert, salt and other harsh environments. smooth wall, and increase transmission efficiency, long service life long plastic-lined steel pipe applications: 1. widely used in chemical, electric power, metallurgy, food, wait for the media industry transportation and environmental processing system. Drinking water projects and water supply and drainage conditions of use of plastic-lined steel pipe: 1. Vacuum (negative pressure) DN25-DN80: ≤ 90Kpa DN100-DN150: ≤ 70Kpa ≥ DN200: ≤ 55Kpa 2. Positive pressure: DN25-DN80: ≤ 6.4MPa DN100-DN150: ≤ 6.4Mpa ≥ DN200 ≤ 2.5Mpa lined with steel pipe use temperature: 1. steel liner polypropylene tube (GSF.PP), medium temperature: -20 ° C to -105 ° C lined PVC pipe (GSF.PVC) Medium temperature: -15 ° C to -65 ° C medium temperature of the steel liner polyethylene pipe: -20 ° C to -80 ° C for 4 lined polyolefin tube (GSF.PO), media work temperature: -15 ° C to -110 ° C steel liner PTFE tube (GSF.F4), medium Operating temperature: -100 ° C -250 ° C www.hbthgg.com www.thgangguan.com www.naimoguanjian.com www.bengguan168. com www.hbbengguan.com www.hbbgc.com www.pvdfgc.com www.naimogd.com
