Popular science on PVC casing for water Wells

1. Material Characteristics: The foundation of safety and durability

① PVC tubing adopts high-density UPVC resin as raw material, mixed with antioxidant, UV absorber and other modified additives during production.

② Lightweight: density 1.4g/cm³, only 20% weight of steel pipe, easy for single-person transportation and installation.

③ Chemical stability: resistant to acid, alkali, salt spray and hydrogen sulfide corrosion, no electrochemical rust risk.

④ Sanitary certified: passes GB/T 17219 drinking water hygiene standard, no sediment accumulation after long-term service.

2. Performance Advantages: Analysis of Engineering Adaptability

① Structural rigidity: ring stiffness ≥8kN/m², excellent anti-collapse performance for deep boreholes.

② High flow efficiency: inner wall roughness Ra ≤0.01mm, 35% lower water resistance compared with metal pipes.

③ Long service life: over 50 years service life under -30℃~60℃ environment, nearly zero maintenance cost.

3. Application Scenarios: From daily life to industry

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

② Geothermal well construction: ideal heat exchange pipeline for ground source heat pump systems.

③ Mine drainage wells: resist acid mine water corrosion to avoid frequent steel pipe replacement.
