 |
PIPES
PRFV WITH LINER THERMOFIX |
 |
The pipe PRFV has
a “liner” (chemical stopper
– internal surface that will be
in contact with liquid the resin has
high resistance to high temperatures,
chemical products and abrasion. There
is the possibility to choose the resin
to be used according of type of liquid.
The thickness of fiber glass layer depends
of pressure class and required rigidity.
• Diameter
: 50 to 700mm ( 2 to 28 inch)
• Pressure
class: up to 32 Kgf/cm2
• Maximum
work temperature : 120o.C |
