Product Overview
About Casing Pipes
Godfill Casing Pipes are manufactured to IS 12818:1992 and are used to line borewells, preventing soil ingress while permitting groundwater inflow through slotted sections. Available in plain (for non-aquifer zones), non-standard plain (for centraliser positions) and slotted variants (for aquifer zones). The threaded coupling system ensures watertight joints that withstand insertion loads. Manufactured from virgin uPVC with UV stabilisers.
