Borewell Pipes and Fittings

What is the Difference Between a Borewell Casing Pipe and a Column Pipe?

A borewell installation uses two distinct pipe types that serve completely different functions. Borewell casing pipes line the drilled borehole from top to bottom, preventing the borehole walls from collapsing inward and keeping soil, sand, and contaminants out of the water extraction zone. They stay permanently in the ground and are never removed. Column pipes for submersible pumps sit inside the casing and carry water from the submersible pump at the bottom of the well up to the surface. They bear the combined weight of the pump, motor assembly, and water column throughout operation. Selecting the right pipe for each function, in the right material and duty class, determines how long the borewell performs without failure. Supreme's pvc pipes for borewell range covers both requirements completely, from casing to column to screen pipes and all accessories.

Which Borewell Casing Pipe is Right for My Well Depth and Soil Condition?

Supreme offers five distinct casing pipe types to cover every well depth and soil condition. Casing Pipes as per IS 12818 are available in Shallow Well and Medium Well variants with V-type or trapezoidal threaded ends for leak-proof connections, with protective caps for transport and storage. Casing Pipes as per ASTM D 1785 are available in SCH 40 and SCH 80 for greater strength in deep well applications. SDR casing pipes are the economical option for shallow wells in favourable soil conditions, supplied in blue colour for easy identification, using solvent weld joints. Ribbed screen pipes use V-shaped ribs to maintain screen permeability in fine sand or specific soil formations where standard slotted pipes would clog. Slotted pipes allow controlled water entry into the well and also support groundwater recharge through percolation pits. To understand casing pipe types and how to select the right one, read our detailed guide on what is a casing pipe and its features and benefits.

Which Column Pipe is Right for My Submersible Pump Installation?

Supreme offers column pipes for submersible pumps in two materials — uPVC and PE — across eight duty classes to match different installation depths and pump loads. uPVC column pipes are available from 25mm to 100mm and are fitted with square threads manufactured to resist shock and jerk loads during pump operation. Couplers are integrally locked using a cord lock provision, ensuring a secure and vibration-resistant connection at every joint. PE column pipes offer the same square thread and coupling system with the added flexibility of polyethylene, suited for installations where slight ground movement is a factor. Both variants cover installation depths up to 450 metres, giving contractors the right specification for shallow domestic borewells through to deep industrial groundwater extraction. Column pipes are lead-free, corrosion-free, and significantly lighter than GI alternatives, reducing installation time and labour cost.

What Are Screen Pipes and Borewell Accessories Used For?

Screen pipes and slotted pipes are installed at the water-bearing zone of the borehole, allowing groundwater to enter the casing while filtering out sand, gravel, and fine particulates. Supreme offers screen pipes in plain and continuous ribbed screen variants, each designed for specific soil and formation conditions. The complete borewell accessories range covers couplers, caps, and adapters for boring pipes and casing connections, and adapters, guards, and clamps for column pipe and submersible pump assemblies. Every accessory is designed to ensure correct alignment, secure connections, and consistent operational performance across the full depth of the installation.
