PVC column pipes are specially designed pipes used in submersible pump systems to lift water from borewells or deep wells. They act as a connection between the pump installed inside the borewell and the outlet at the surface.

PVC stands for Polyvinyl Chloride. These pipes are usually made from uPVC material, which is strong, rigid, and suitable for water applications.

Description

PVC column pipes are vertical pipes that carry water upward when a submersible pump is running. They are designed to handle the weight of the pump, water column, and vibration during operation. These pipes are widely used in agriculture, domestic water supply, and industrial applications.

Key Features

High tensile strength to handle load of pump and water
Corrosion resistant and rust free
Lightweight and easy to install
Leak proof threaded or coupled joints
Smooth inner surface for better water flow
Long service life with low maintenance

Types

Threaded column pipes with male and female threads
Coupled pipes using separate couplers
Plain and ribbed pipes for different strength needs

Sizes and Specifications

Diameter usually from 1 inch to 6 inch
Length commonly 3 meters per pipe
Pressure rating depends on borewell depth and pump capacity
Made from uPVC material

Applications

Borewell and deep well water lifting
Submersible pump installations
Agricultural irrigation
Domestic water supply
Industrial water systems

Advantages

No rust or scaling compared to metal pipes
Easy handling and transportation
Lower installation cost
Better flow due to smooth surface

Limitations

Not suitable for high temperature water
Can crack if handled roughly
Proper installation required for long life

Summary
PVC column pipes are a reliable and cost effective solution for lifting water from borewells especially in agricultural and domestic use due to their strength durability
