Ciencia popular sobre revestimiento de PVC para pozos de agua

1. Material Properties: Foundation of Safety and Durability

① PVC well casing is mainly made of high-density unplasticized polyvinyl chloride (UPVC) resin, blended with modified additives such as antioxidants and UV absorbers.

② Lightweight: Density reaches 1.4 g/cm³, only 20% of steel pipe; one person can carry and install it.

③ Chemical inertness: Resists corrosion from acids, alkalis, salt spray and hydrogen sulfide, with no risk of electrochemical oxidation.

④ Sanitation certification: Passed drinking water hygiene standard GB/T 17219, no sediment accumulation after long-term service.

2. Performance Advantages: Engineering Adaptability Analysis

① Structural strength: Ring stiffness ≥8kN/m², delivers strong anti-collapse performance for deep wells.

② Fluid efficiency: Inner wall roughness Ra ≤0.01mm, reduces water flow resistance by 35% compared with metal pipes.

③ Service life: Over 50 years of service within -30℃ ~ 60℃ environment, nearly zero maintenance cost.

3. Application Scenarios: From Daily Life to Industry

① Rural safe drinking water projects: Eliminates rust and algae growth issues.

② Geothermal well construction: Ideal heat exchange channel for ground source heat pump systems.

③ Mine drainage wells: Resists acid mine water corrosion, avoiding frequent replacement of traditional steel pipes.

4. Customized Solutions

JCDRILL specializes in non-standard design:

① Size customization: Supports diameters from 50 mm to 800 mm, wall thickness tolerance controlled within ±0.2 mm.

② Functional upgrade: Can be compounded with fiberglass layer to improve impact resistance, or added conductive coating for anti-static requirements.

③ Regional adaptation: Formula parameters adjusted for special geological conditions such as permafrost, high salinity and alkalinity.
