Lined plastic pipeline
Lined plastic pipeline is made of ordinary carbon steel pipe as the matrix, lined with thermoplastic engineering plastic with excellent chemical stability. It is formed by cold drawing composite or rolling molding. It has both the mechanical properties of steel pipe and the corrosion resistance, slow scaling, and resistance to microbial growth of engineering plastic. It is an ideal pipeline for transporting media such as acid, alkali, salt, and corrosive gases. Lined with food grade polypropylene, it can be used in industries such as food, medicine, and drinking water. Common plastic lined pipelines include steel lined polypropylene pipes (GSF. PP), steel lined polyvinyl chloride pipes (GSF. PVC), steel lined polyethylene pipes (GSF. PE), steel lined polyolefin pipes (GSF. PO), and steel lined polytetrafluoroethylene pipes (GSF. F4).
characteristic:
1. Has excellent physical properties
2. It has corrosion resistance performance
3. The mechanical strength is the same as that of steel pipes
4. It is hygienic, non-toxic, does not accumulate dirt, does not breed microorganisms, and ensures fluid quality
5. Resistant to chemical corrosion, soil and marine biological corrosion, and cathodic stripping
6. Mature installation technology, convenient and fast
7. Good weather resistance, suitable for harsh environments such as deserts, saline alkali, etc
8. Smooth pipe wall, improved conveying efficiency, and long service life
Application areas:
1. Chemical industry: Process pipes and discharge pipes for transporting corrosive gases, liquids, solid powders in industries such as acid, alkali, salt manufacturing, fertilizers, pesticides, chemicals, rubber and plastics.
2. Power engineering: transportation of process water return, chemical water, waste residue, and fly ash.
3. Smelting industry: transportation of corrosive media in metal smelting.
4. Mining industry: discharge of mineral powder, slurry, slag, tailings, backfilling, ventilation, gas drainage, and spraying.
5. Pharmaceutical industry: transporting various corrosive media, sewage, and wastewater.
6. Oil and gas fields: oily wastewater, gas field wastewater, oil and gas mixtures, oil production and gathering pipelines.
7. Agricultural sprinkler irrigation: deep well pipes, filter pipes, culvert conveying pipes, drainage pipes, irrigation water supply pipes.
8. Municipal industry: urban building water supply, drinking water, fire water, heating network return water, gas and natural gas transportation, underground drainage of highways, and irrigation of green belts and other channels.
Operating temperature:
1. Working temperature of medium for steel lined polypropylene pipe (GSF. PP):- 20℃～105℃
2. Working temperature of medium for steel lined polyvinyl chloride pipe (GSF. PVC):- 15℃～65℃
3. Working temperature of medium for steel lined polyethylene pipes:- 20℃～80℃
4. Working temperature of medium for steel lined polyolefin pipe (GSF. PO):- 15℃～110℃
5. Working temperature of medium for steel lined polytetrafluoroethylene pipe (GSF. F4): -100 ℃ to 250 ℃
The plastic lined steel pipe is a composite steel pipe made of a variety of modified blend polymers and steel pipes through a special process. It not only retains the strength of the steel pipe and the traditional connection method, but also gives full play to the corrosion resistance, aging resistance, high wear resistance, rust free, non-toxic, smooth inner wall and other characteristics of plastic materials through different modifications of plastic materials. Modified corrosion-resistant plastic lined steel pipes are alternative products for industrial pipelines in industries such as petroleum, chemical, power, coal, shipping, and ports
