Shandong Rainbow lined pipes] [lowering the price to build corporate purchasing carnival. Ordinary carbon steel-lined steel pipe is used as the substrate, excellent chemical stability lined thermoplastic, composite or by cold drawing rotational molding, it is both corrosion resistance and mechanical properties of steel, there are plastic tubes, slow fouling and difficult growth of microorganisms features, is transport acid, alkali ideal pipeline, salt, corrosive gases and other media. Lined with food-grade polypropylene, it can be used for food, medicine and drinking water and other industries. Common plastic-lined steel pipe are: polypropylene steel liner tube (GSF.PP), steel-lined PVC pipe (GSF.PVC), steel liner polyethylene pipe, steel-lined polyolefin pipe (GSF.PO) steel liner polytetrafluoroethylene fluoride tube (GSF.F4). Lined pipe Features: 1. 2 having excellent physical properties. It has excellent corrosion resistance 3. The mechanical strength of steel pipe 4 are the same. Health non-toxic, non-fouling, non-breeding microorganisms, fluid quality assurance 5. Chemical resistant, corrosion-resistant soil and marine life, resistance to cathodic stripping 6. Installation process maturity, convenient 7. Weather is good for the desert, salt and other harsh environments 8. Smooth wall, improve transport efficiency, long life lined pipe temperature 1. polypropylene steel liner tube (GSF.PP) of medium temperature: -20 ℃ ~ 105 ℃ 2. steel lined PVC pipe (GSF .PVC) The medium temperature: -15 ℃ ~ 65 ℃ 3. steel liner polyethylene pipe (GSF.PE) of medium temperature: -20 ℃ ~ 80 ℃ 4. steel lined polyolefin pipe (GSF.PO) of medium temperature: -15 ℃ ~ 110 ℃ 5. steel liner PTFE tube (GSF.F4) of medium temperature: -100 ℃ ~ 250 ℃ lined pipe Advantages 1. products using advanced rotational molding process as a whole molding; 2. lining high density, high integrity, no stress; 3.
