PVC-U Well Casing and Screen Pipes for Water Well Construction

Highest Quality uPVC Well Casing and Screen Pipes for Water Well Construction

Casing Pipes & Screen Pipes are used for Bore Hole / Bore Well application. It prevents the earth to fill the Bore well and the Screen allows the water to percolate in the well which can be pumped with the pump.

Vinyl uPVC Casing & Screen Pipes has a higher density than water that provides a clear advantage in good construction. Its yield stress of 55Nlimm is comparatively high. The modulus of elasticity is also high enough to achieve excellent stiffness in pipes preventing undesired deformation of the pipe.

  • Corrosion & Bacteria Resistance.
  • Resistant to all substances dissolved in natural ground waters.
  • Resistant to aggressive and highly concentrated acids and salts.
  • Completely resistant to bacteria in water and soil.

Material

PVC-U, unplasticised polyvinyl chloride is an ideal material for manufacturing well pipes as it is impervious to corrosion and chemical action, easy to handle and install, light in weight, non-toxic, non-conductive. Its long service life makes it an economical choice over other materials.

Screen Permeability

The possible production capacity of a well basically depends on the following factors:

  • Permeability and yield of the water-bearing strata
  • Permeability of the filtering gravel
  • Permeability of the good screen
  • Entrance velocity of the water at the screen
