Typical properties that result in advantages in GRP pipes application can be summarised as follows:

• High mechanical resistance due to the glass reinforcement.
• Corrosion resistance, both the external wall and internal wall in contact with the conveyed fluid. No protections such as coating, painting or cathode are needed. GRP pipes are resistant to nearly all chemicals.
• Smoothness of the internal wall minimizes the head losses and avoids the formation of deposits. In contrast to steel, cast iron and concrete, GRP pipe maintains initial smoothness through all exploitation period
• Very long life, virtually infinite, of the material, which does not need maintenance.
• Absolute impermeability of pipes and joints both from internal to external and vice-versa.
• Low weight of pipes which allows the use of light laying and transport equipment.
• Long pipe sections, longer than pipes made with other materials, resulting in fast installation and less joints.
• Workability of the material on site with the use of simple tools. It is possible to make any kind of shapes (tees, elbows…), joints and connections.
• Possibility of nesting, different diameters of pipe can be nested during transport, allowing additional saving in transport operations.
