A structured evaluation of the best casing pipe for borewell construction must address both the drilling phase and operational requirements. During drilling, the casing must withstand jacking loads and impact forces. In operation, it must resist collapse from external water table fluctuations and confining soil pressure. Threaded couplings used with column sections must maintain alignment under pump torque loads. Centralizer spacing ensures the casing string remains plumb, preventing pump eccentricity. Filter pack design around the screened section interacts with slot size specifications, making casing selection a system-level decision.
