1. What are DN100 PVC Pipes for Well Casings?
DN100 PVC pipes for well casings are professionally engineered polyvinyl chloride (PVC) pipes with a nominal diameter of 100mm, deployed as protective liners in boreholes and wells. These pipes shield water sources and maintain well integrity by preventing soil and contaminant intrusion, ensuring stable and long-lasting water extraction capabilities. The DN100 denomination corresponds to an internal diameter of approximately 100mm, making these pipes suitable for medium to large groundwater extraction systems, agricultural irrigation, mining dewatering, or municipal supply infrastructure.

11. FAQ – Technical Terms Explained
Q1: What is the raw material specification for DN100 PVC pipes for well casings?
DN100 PVC pipes for well casings are made from unplasticized polyvinyl chloride (PVC-U), free from hazardous heavy metals and compliant with ISO 1452 for potable water safety and chemical resistance.
Q2: What is meant by 'Pressure Rating (PN)'?
'PN' refers to Nominal Pressure—an indicator of the working pressure the pipe can safely endure in bar (e.g., PN10 = 10 bar/145 psi). Choose the rating based on well depth and hydrostatic load.
Q3: What installation standards should be followed?
Installation should conform to standards such as ISO 11722 (well casing) and ANSI/AWWA A100 (water wells), ensuring joints are correctly torqued and pipes are properly aligned vertically.
Q4: How does wall thickness classification work?
Wall thickness is defined by pipe Class or SDR (Standard Dimension Ratio). DN100 common classes: Class 10 (4.2mm wall), Class 12.5 (5.4mm wall); higher class = greater burst strength.
Q5: Can DN100 PVC pipes for well casings be used in thermal wells?
Yes, but with temperature limitations: max 45–60°C for continuous operation, as per ISO/TR 7473. For higher temperatures, consider FRP or special-engineered PVC grades.
Q6: What quality certifications are most relevant?
ISO 1452 (PVC piping systems), ANSI/NSF 61 (drinking water), and WRAS (UK Water Regulation) are international certifications for material and performance compliance.
Q7: What after-sales service is provided?
Warranty (5 years), installation consultation, pressure/hydrostatic testing support, and site-inspection for troubleshooting. Full technical files and digital manuals are available on request.
Rigorously engineered to international standards, DN100 PVC pipes for well casings have become the market benchmark for efficiency, longevity, and compliance with evolving regulatory mandates. Whether for rural irrigation, municipal water supplies, or industrial groundwater abstraction, these pipes guarantee the lowest lifetime cost of ownership with the strongest environmental and technical credentials—verified by field results and client feedback worldwide.
