How to Select the Right Size and Thickness for PVC Casing Pipes
Selecting the correct PVC casing pipe size and thickness is a critical decision in borewell and tube well construction. The right choice ensures structural stability, protects groundwater sources, prevents bore collapse, and extends the life of the well system. This guide explains everything you need to know about pvc casing pipe selection, sizes, thickness grades, depth suitability, and applicable standards - based on Utkarsh Pipes and Fittings manufacturing specifications.
Understanding PVC Casing Pipes
A PVC casing pipe is installed inside borewells or tube wells to support the bore structure, prevent soil ingress, and protect pumps and water-bearing strata. Compared to traditional metal casings, PVC casing pipes offer excellent corrosion resistance, long service life, and easy installation.
Utkarsh Pipes manufactures PVC casing pipes suitable for shallow, medium, and deep borewells, adhering to both Indian and international standards.

This comprehensive PVC casing pipe size chart helps ensure accurate PVC casing pipe selection for domestic, agricultural, and industrial borewell applications. Choosing the correct diameter depends on borewell depth, pump size, and geological conditions.
Selecting PVC Casing Pipes Based on Tube Well Depth
Depth plays a decisive role in determining pipe thickness and strength. Utkarsh Pipes categorises casing pipes based on borewell depth to ensure optimal load resistance and durability.
Casing Pipes by Borewell Depth
Casing Shallow (CS) Pipe
Suitable for wells up to 80 metres (262 ft)
Ideal for domestic and low-pressure applications
Casing Medium (CM) Pipe
Designed for depths above 80 metres up to 250 metres (820 ft)
Recommended for moderate geological pressure conditions
Casing Deep (CD) Pipe
Engineered for depths above 250 metres up to 450 metres (1476 ft)
Suitable for high-load, deep borewell installations
Matching the casing type with borewell depth is essential for long-term performance and structural safety.
Importance of Thickness and Schedule Selection
Thickness determines the pipe’s ability to withstand soil pressure, water pressure, and installation stress.
Schedule 40 PVC casing pipes are suitable for moderate depth wells with standard pressure requirements.
Schedule 80 PVC casing pipes offer higher wall thickness, making them ideal for deep borewells and high-pressure applications.
Selecting the correct schedule ensures the pipe maintains integrity throughout its service life.

Key Factors to Consider for PVC Casing Pipe Selection
When selecting the right PVC casing pipe, consider the following:
- Borewell Depth – Determines casing type (CS, CM, or CD)
- Pipe Diameter – Based on pump size and water yield
- Thickness & Schedule – Schedule 40 or Schedule 80
- Soil & Geological Conditions – Clay, sand, or rocky strata
- Compliance with Standards – IS, ASTM, and DIN certifications
A proper evaluation of these factors ensures optimal performance and reduced maintenance costs.
