C.R.I. uPVC casing and screening pipes are as per IS 12818:2010 standards. They are
available in different sizes ranging from 40mm to 300mm. These pipes can be used in any of
the irrigation, domestic, mining and industrial boreholes, helping to keep put the gravel pack
and foreign particles, providing clean & clear water. Well casing pipes are necessary to
exclude the shallow groundwater, protect the pump and support the unstable layers of loose
soil and rock from collapsing into the boreholes. C.R.I. uPVC are provided with trapezoidal
threads which provide easy and strong points. These pipes has horizontal slots which enables
laminar flow into the well ensuring higher permeability and reducing well entrances losses,
thus saving the pumping energy and offer higher yields.
