Borewell Contractors in Selaiyur

Borewell Contractors in Selaiyur, Currently, PVC pipes are very widely used as casing pipe. GI/Mild steel casing pipes which were used earlier are not being recommended due to the problem of corrosion. PVC casing pipes installed in borewells must confirm to IS 12818: 1992 that governs the specification for unplasticized PVC screen and casing pipes for borewell of the Bureau of Indian standard. This standard covers the requirements of ribbed screen, plain screen and plain casing pipes of nominal diameter 40 to 400 mm produced from unplasticized polyvinyl chloride for borewell for water supply. Drillers won’t be inclined to do so as this is an additional task they have to do. Based on their experience, they tell the rough yield which may not be always correct. Yield of a borewell is usually referred in inches (i.e. depth of water flowing over the notch).
