The excellent physical and chemical characteristics of the raw materials and the precision of the manufacturing processes make the tubes ideal for the construction of wells for water, being characterized by: • high resistance to corrosion; • absence of fouling; • long life. PVC pipes are most effective in different executions of wells, particularly in the presence of underground waters are very aggressive and different chemical composition. Pipes and filters are available with a wide range of diameters and thicknesses with many types of threaded joints or standard glass to be riveted or special request, conform to DIN4925 and DM Ranked # 174 04/2004 regarding suitability for contact with potable water.
