Application Scenarios for DN100 PVC Well Casings

Residential Water Wells

DN100 PVC pipes for well casings are ideal for domestic water supply systems with depths ranging from 30 to 150 meters. The smooth interior surface reduces pump friction loss by up to 25% compared to traditional materials. HORON's formulations resist iron bacteria buildup and maintain water quality by preventing leaching of contaminants into the aquifer.

Agricultural Irrigation

Farm water systems benefit from the chemical resistance of DN100 PVC pipes for well casings in areas with high fertilizer and pesticide usage. The lightweight nature reduces installation time by 40% compared to steel casings. Special perforated designs are available with laser-cut slots ranging from 0.5-2.0mm to optimize water entry while filtering sediment.

Geotechnical Monitoring

Environmental engineers utilize DN100 PVC pipes for well casings in groundwater monitoring networks due to their chemical inertness. These casings provide accurate water quality sampling with minimal interference. Special food-grade formulations are available for installations requiring ultra-pure sampling conditions.

Industrial Water Supply

Manufacturing facilities with high-volume water requirements rely on DN100 PVC pipes for well casings for their corrosion resistance in challenging geological formations. HORON provides reinforced designs with increased hoop strength for installations in collapsing sand or gravel formations where standard casings may deform.

Technical Questions About DN100 PVC Well Casings

What pressure class is recommended for different well depths?

Pressure class selection for DN100 PVC pipes for well casings depends on depth and groundwater conditions:

Class 4 (125 PSI): Suitable for depths to 80 meters
Class 6 (180 PSI): Recommended for 80-150 meter wells
Class 9 (235 PSI): Required for deep wells exceeding 150 meters
Class 12 (315 PSI): For exceptionally deep wells or artesian conditions

HORON INTERNATIONAL provides certified pressure ratings according to ISO 4065 with a minimum safety factor of 2:1.

How do temperature variations affect DN100 PVC well casing performance?

PVC expands approximately 0.06mm per meter per °C temperature change. For DN100 PVC pipes for well casings, the coefficient of thermal expansion is 6×10⁻⁵ K⁻¹. This requires specific installation considerations:

Allow expansion gaps in above-ground installations
Use restrained joints below frost line depth
In sub-zero environments, thermal contraction must be compensated
Maximum thermal cycling tolerance: -20°C to +50°C daily variation

What thread types are available for DN100 PVC well casings?

HORON offers three standard threading options for DN100 PVC pipes for well casings:

NPT (National Pipe Taper): ANSI/ASME B1.20.1 compliant 11.5 TPI threads
BSPT (British Standard Pipe Taper): ISO 7-1 compliant 11 TPI threads
Continuous Thread: Special design for quick-make connections

All threads are machined to ±0.1mm tolerance using CNC threading equipment to ensure pressure integrity.

Are DN100 PVC casings suitable for saline groundwater environments?

Yes, PVC offers excellent resistance to saline environments at concentrations up to 50,000 ppm TDS. DN100 PVC pipes for well casings maintain structural integrity even in brackish groundwater conditions. At chloride concentrations above 30,000 ppm, we recommend thicker-walled designs (minimum DR18) to compensate for slight plasticization effects.

What joint sealing systems are used in PVC well casings?

HORON INTERNATIONAL utilizes three sealing technologies in DN100 PVC pipes for well casings:

Compression Seal Systems: EPDM O-rings with 35±5 Shore A hardness
Tapered Thread Seals: PTFE tape with thread sealant compound
Solvent-Weld Joints: NSF-approved PVC cement creates homogeneous bonds

Pressure testing confirms zero leakage at 1.5 times working pressure for all joint types.

How does UV radiation affect above-ground PVC well casing installations?

Unprotected PVC experiences degradation at approximately 0.01mm/year when exposed to direct UV radiation. For DN100 PVC pipes for well casings in exposed applications:
