uPVC Casing Pipes

AS PER IS 12818:2010

Casing pipes for Borewells/Tubewells

NATRAJ uPVC Casing & Screen (Filter) Pipes are manufactured as per IS 12818:2010 for the purpose of construction of the tubewells and borewells which is then used for lowering the pumps inside it for drawing water from the underground waterbed. These Borewells or Tubewells are one of the major sources of potable ground water in India specially for the rural areas.

In a typical borewell system screens pipes are positioned at the water bearing levels usually at the bottom to filter sand particles from water followed by casing pipes on top. In general cases same size of strainer and casing pipes is used for the entire system. However in specific cases to accommodate the pump set and to get higher yield at the upper levels higher size of casing pipes is also used which is attached to lower system using reducers.

uPVC Pipes being more resilient, non-corrosive and economical has successfully and effectively replaced the conventional metal piping materials.

Borewells and tubewells

High Resistance To Bore Collapse

Designed to withstand external soil pressure and bore stress, helping protect well walls and maintain pipe integrity in drilled borewells and tubewells across demanding underground conditions.

Secure Threaded Joint Strength

Precision threaded joints create firm, aligned connections between pipe lengths, supporting dependable vertical installation and long term borewell performance at varying depths.

Efficient Slotted Water Intake

Uniform screen slots allow groundwater to enter while helping reduce movement of sand, soil and loose particles into the well system for cleaner and more reliable water intake.

Corrosion And Chemical Resistance

uPVC resists rust, corrosion and many underground chemical effects, making the pipes suitable for long term use in varied soil and groundwater conditions.

Lightweight For Easy Installation

Lightweight pipe sections are easier to transport, lower, join and align at site, reducing handling effort during borewell and tubewell installation work.

Long Life Underground Use

Offers dependable dimensional stability and long service life underground, supporting domestic, agricultural and institutional well applications over extended use.
