The internal coating with epoxy resins for the transportation of water for human consumption is used to protect pipes from corrosion and also to smooth internal surface in order to reduce drag losses due to friction. The epoxy resins used do not release any toxic or polluting elements and conform to the Italian Ministry of Health Note Nr. 102 dated 02.12.1978 and updates as DM N° 174 dated 06.04.2004.

The internal surface is sandblasted by metallic grit up to SA 2.5 – SA 3 grade according to ISO 8501-1 standard then epoxy resins from 100 up to 500 microns are applied using airless bimixer. After drying the coating is visually inspected, checked on dimensions (thickness) and technologically tested.
