IS 18166 : 2025 Unplasticized Polyvinyl Chloride (PVC-U) Threaded Column Pipes for Borewells/Tubewells - Specification
1 SCOPE
1.1 This standard covers the requirements of unplasticized polyvinyl chloride (PVC-U) threaded column pipes of the following types and sizes, for use with jet or submersible pumps in borewells/tubewells for water supply: a) Bell ended (socketed) type with external thread at spigot end and internal thread at bell (socket) end, of nominal sizes 25 mm, 32 mm and 40 mm; and b) Coupler joint type with external threads at both ends, connected with coupler, of nominal sizes 25 mm to 150 mm.
1.2 These pipes are recommended for water temperatures ranging from 1 °C to 45 °C.
