With the popularization of people’s awareness of environmental protection and health, new types of environmental protection water supply pipes have sprung up like mushrooms after rain, and their varieties are hard to enumerate. Plastic-lined steel pipes inherit the advantages of steel pipes and plastic pipes while abandoning their respective shortcomings. One of the most important contents in pipe design is to reasonably determine the wall thickness of the pipe according to the conditions of use and requirements, and this parameter directly affects the cost performance of the product.
The advantages of lined pipes in the following:
1. Has excellent physical properties
2. Has excellent corrosion resistance
3. Mechanical strength is the same as steel pipe
4. Hygienic, non-toxic, no fouling, no growth of microorganisms, and ensure fluid quality
5. Resistant to chemical corrosion, soil and marine organisms, cathodic disbondment
6. The installation process is mature, convenient and fast
7. Good weather resistance, suitable for harsh environments such as deserts and saline alkalis
8. Smooth pipe wall, improve conveying efficiency and long service life
Application areas of plastic-lined pipes:
1. Chemical industry: technical pipes and discharge pipes for transporting corrosive gases, liquids, and solid powders in the production of acids, alkalis, salts, fertilizers, chemicals, rubber and plastics, and other industries.
2. Electric power engineering: technical water return water transportation, chemical water, waste residue, fly ash transportation.
3. Forging occupation: transportation of corrosive medium in metal forging.
4. Occupation: discharge of ore powder, pulp, slag, tailings, backfill, ventilation, gas drainage, shotcrete, etc.
5. Pharmaceutical industry: transporting various corrosive media, sewage, and wastewater.
6. Oil field and gas field: oily sewage, gas field sewage, oil and gas mixture, oil production and gathering, and transportation technical pipelines.
7. Agricultural sprinkler irrigation: deep well pipe, water filter pipe, underdrain transportation pipe, drainage pipe, irrigation water supply pipe.
8. Municipal occupation: urban construction of water supply, drinking water, fire water, heat network return water, gas, gas transportation, highway buried drainage, and green belt irrigation and other channels.
