The company Paparelli Alessandro e Figlio started producing pipes and well screens in the 1950-s. Today, Paparelli places 35 % of their products on the Italian market, and the remaining 65 % is placed on the European, Asian, African and South American markets.
Paparalli produces everything necessary to form a line: casing, spiral screens, bridge sloted screens, simple sloted screens and additional equipment (such as collars, flanges, reductions, centralizers, caps etc.)
The casing and screens are made from tin between 3 and 10 mm thickness, with a minimum diameter of 114 mm.Materials are carbon steel (FE 37 – FE 52), black or galvanized and stainless steel (304, 304L, 316, 316L).
The selection of the material depends on the purpose of the line (potable water, drainage, desalinization, spa and pools, industry, research etc.), on the geological situation, the power conditions for drilling, the chemical aggression of water and on corrosion.
