Pipes, fittings and valves for cold water and chemicals

The resin used by GIRPI has a high kwert (minimum viscosity index of 62) allowing a perfect fit with pipes certified by quality label. This kwert is particulary recommended when working pressures go up and down.


Working temperature: from +5C to +60C
Diameter from 16mm to 315mm

Working pressure at 20C:

PN25 bar for diameter 16 to 20mm
PN16 bar for diameter 25 to 160mm
PN10 bar for diameter 200 to 315mm
