Plastic-lined pipes are based on ordinary carbon galvanized steel pipes, lined with thermoplastics with good chemical properties, and are cold-drawn composite or rotomolded. They have the mechanical properties of steel pipes and the corrosion resistance of plastic pipes. It is slow to scale and difficult to grow microorganisms. It is an ideal pipeline for transporting acid, alkali, salt, corrosive gas and other media.

Usage:

1. Chemical industry: process pipes and discharge pipes for transporting corrosive gases, liquids, solid powders in the manufacturing industries of acid, alkali and salt, fertilizers, pesticides, chemicals, rubber and plastics.

2. Electric power engineering: power plant process water return water transportation, chemical water, waste residue, and fly ash transportation.

3. Smelting industry: transportation of corrosive media in metal smelting.

4. Mining industry: discharge of ore powder, slurry, slag, tailings, backfilling, ventilation, gas drainage and shotcrete, etc.

5. Pharmaceutical industry: transporting various corrosive media, sewage, and wastewater.

6. Oil and gas fields: oily sewage, gas field sewage, oil and gas mixtures, oil production and gathering and transportation process pipelines.

7. Agricultural sprinkler irrigation: deep well pipes, water filter pipes, underdrain conveying pipes, drainage pipes, and irrigation water supply pipes.

8. Municipal industry: urban building water supply, drinking water, fire water, heating network return water, gas, natural gas transportation, highway underground drainage and green belt irrigation and other channels.
