Benefits
Long Service Life:
- Pipes are designed in compliance with the international standards to serve a minimum of 50 years. Operating and maintenance costs are negligibly small.
Perfect and smooth inner surface:
- The smooth inner surface of SUPERLIT GRP pipes reduces hydraulic losses. Thanks to its smooth inner surface, friction loss is at a minimum, and it keeps this characteristic throughout its entire service life.
Safe connections:
- SUPERLIT GRP pipe joints are designed with the flexible connection method, and the sealing is provided by couplings having full-face integrated elastomeric seal.
Lightweight:
- It has approximately 1/4 the weight of steel pipes, approximately 1/5 of ductile pipes, and approximately 1/10 of concrete pipes.
- GRP pipes with varying diameters can be nested together and thus, more pipes can be transported using less vehicles. This means the cost of transportation can be lowered.
- Installation is fast and easy.
- Requires no special equipment for handling and mounting. Being lightweight means easy installation, even for longer pipe lengths.
Resistance against corrosion and chemicals:
- It does not corrode since it is not manufactured with metallic materials.
- As a standard, it is designed to serve in a wide pH range.
- It has insulation properties and is not influenced by electric current.
- It does not require cathodic protection.
- It does not require inner and outer coating.
Surge pressure absorption:
- Additional pressure increases occurring due to surges are far less when compared with metal pipes. They are designed to absorb 40% of the surge pressure, without increasing the pressure class.
GRP Pipe Diameters and Technical Properties

Technical Properties
Flow Rate
- Recommended flow rate for the standard GRP pipe is 4 m/s maximum. Pipes allowing a higher flow rate can be manufactured by special design.
Flow Coefficient
Ratings to be used in hydraulic calculations for SUPERLIT GRP pipes:
-
- Hazen–William flow coefficient: C = 150
- Manning coefficient: n = 0,009
- Colebrook–White coefficient:
k = 0,029 mm for the pipes manufactured by the continuous filament winding method.
k = 0,012 mm for the pipes manufactured by the centrifugal casting method.
UV Resistance
- Performance of GRP pipes is not negatively affected by UV rays. Observing color changes on the surface, which do not affect the strength, is normal.
Poisson Ratio
- Poisson ratio that can be used in standard engineering calculations for GRP pipes is between 0,22 – 0,29.
Temperature
- Service temperature of standard GRP pipes is between -40 ̊C and +35 ̊C. Special pipes can be designed for service temperatures up to 50 ̊C.
Thermal Coefficient
- Thermal expansion and contraction coefficient of SUPERLIT GRP pipes in axial direction:
between 24 and 30 x (1/106) mm/mm/°C
