Glass reinforced plastic pipes represent the ideal solution for supply of water, chemicals, effluent and sewers, because they combine the advantage of corrosion resistance typical of plastics with a mechanical strength comparable with steel. Typical advantages of GRP pipes compared to steel pipes can be summarized as follows:

• Pipes are lighter in weight which allows for easy laying and transportation.

• Different diameter pipes can be nested, contributing to savings in transport operations.

• Easy installation with the use of mechanical bell and spigot joint.

• Corrosion resistance of both the external and internal walls in contact with the conveyed fluid. No coating, painting or cathodic protection are required.

• Smoothness of internal wall minimizes the head losses and avoids the formation of deposits.

• High mechanical resistance due to the glass reinforcement.

• Absolute impermeability of pipes and joints both from external to internal and vice-versa.

• Very long life and maintenance free.

• Easy workability of the material on-site employing simple equipments.
