Popular science on PVC casing for water Wells

1.Material Characteristics: The foundation of safety and durability

① PVC tubing is made of high-density polyvinyl chloride resin (UPVC) as the main material and is produced by adding modified components such as antioxidants and UV absorbers.

②Lightweight: With a density of 1.4g/cm³, it is only 20% of that of steel pipes and can be moved and installed by a single person.

③ Chemical inertness: Resistant to acid, alkali, salt spray and hydrogen sulfide corrosion, with no risk of electrochemical rusting.

④Hygiene certification: Passed the GB/T 17219 drinking water hygiene standard test, with no sediment after long-term use.

2. Performance Advantages: Analysis of Engineering Adaptability

① Structural strength: Ring stiffness ≥8kN/m², and the deep wellbore has strong anti-collapse ability.

② Fluid efficiency: The inner wall smoothness Ra is ≤0.01mm, reducing water flow resistance by 35% compared with metal pipes.

③ Life cycle: It has a service life of over 50 years in an environment ranging from -30℃ to 60℃, and the maintenance cost is close to zero.

3. Application Scenarios: From daily life to industry

① Rural safe drinking water project: Eliminate the problems of rust and algae growth.

② Construction of geothermal Wells: As an ideal heat exchange channel for ground source heat pump systems.

③ Mine drainage well: Resistant to corrosion by acidic water in the mine, avoiding the frequent replacement of traditional steel.

4. Customized Solutions

JCDRILL focuses on non-standard design:

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

② Function upgrade: It can be compounded with a glass fiber layer to enhance impact resistance, or a conductive coating can be added to prevent static electricity.

③ Regional adaptation: Adjust the formula parameters for special geological conditions such as permafrost and high salinity and alkalinity.
