GENERAL INFORMATION:

Glass Reinforced Polyester pipes are manufactured from polyester resins and fibrous glass reinforcements and depending on type with inorganic filler. The design philosophy of GRP pipes is to provide products with suitable properties and the required margin of safety, that will enable the pipe perform satisfactory after an extended period of operation (more of 50 years) under typical service conditions.



?Glass reinforced Polyester pipes represent the ideal solution for the abduction of any kind of water, chemicals, affluent and sewers, because they combine the advantage of corrosion resistance, typical of plastics, with a mechanical strength which can be compared with the steel one. Typical properties that result in advantages in G.R.P. pipes application, can be summarized as follows:



Corrosion resistance, both of the external wall and internal wall in contact with the conveyed fluid. No protections such as coating, painting or cathodic are nedeed. GRP pipes are resistant to nearly all chemicals even at much higher temperatures (up to 170 °C) than other plastic materials.



?Smoothness of the internal wall that minimizes the head losses and avoids the formation of deposits on the other hand minimizes the slope.

TECHNICAL DATA:

Diameter: Normal size of pipe and fitting is based on internal diameter. The range of available sizes is 25 to 3000 mm.

Special application diameters are available upon request.



Lengths: Pipes are manufactured in a standard 3, 5, 6 and 12 meter length.

Special lengths are available upon request.



Pressure: Standard pressure classes are 4, 6, 10, 16, 20 and 25 bars. Intermediate or higher-pressure classes are considered on request or depending on the design parameters and conditions.



Stiffness: Standard stiffness classes are 1250, 2500, 5000 and 10000 Pa. Intermediate or higher stiffness classes are available on request or depending on the design conditions.
