Product Scope
1-Diameter
Faratec pipes can be supplied in the following nominal diameters (mm). Smaller and other diameters are available on request. Please contact Farassan Company for more information
Continuous Filament Winding
Discontinuous Filament Winding
2-Length
The standard length of Faratec pipes for diameters over 300 mm is 12 meters, for diameters 100 to 300 mm is 6 meters and for diameters less than 100 mm is 3 meters. Any other length could also be supplied for special orders.
3-Pressure
Typical pressure classes of Faratec pipes are listed in the following table. Contact the manufacturer if you are requesting a higher working pressure. Faratec pipes can be produced up to 100 bars working pressure at lower diameters.
The working pressure of the pipes has been calculated according to AWWA M45 standard. Pressure classification is determined based on the maximum pressure at operation time and does not depend on the depth of the pipe burial.
Faratec pipes are manufactured in a wide range of diameters up to 4000 mm (157 inches) and maximum working pressure of 100 bars (1450 PSI). These pipes due to their structure could be designed for a variety of fluids with various pH conditions (acid or base) and have a high resistance to corrosion in chemical environments. Some of the mechanical properties of Faratec Uni-Axial and Bi-Axial pipes are shown in the table below compared to steel and GRE pipes.
* Average quantity
** New pipe with cement lining. Roughness increases exponentially over time.
*** The range of mechanical strength value is based on AWWA M11. Referring to the API 5L, value of 207 for the metal pipe is the minimum resistance for the pipe made at Grade A.
The values in the table are merely for comparison purposes. Please contact Farassan Company for precise values if required.
4-In order to ensure long lifespan service of the pipeline, the following tips should be noted:
5-Water Hammer
Internal shocks, most notably water hammer effect, are due to a sudden change in fluid velocity inside the system which is usually caused by rapid closing or opening the valves, or the sudden start-stop of the pumps. Low modulus of elasticity of GRP pipes in comparison with metal pipes makes it possible to reduce water hammer effect in the system. Faratec pipes are able to withstand water hammer at various pressure levels according to the following formula. This approximate formula is used to determine the pressure changes at certain points in a direct pipeline, neglecting the slight friction loss.
6-Stiffness
Faratec pipes are manufactured in following standard stiffness:
7-Flow Velocity
The permitted flow velocity in Faratec pipes is 3 m/s which could be increased in the absence of abrasive materials in the fluid up to 9 m/s. Please contact Farassan Company for more information.
8-Operating Temperature
Faratec pipes have the ability to be designed for fluid transfer temperatures up to 160 ºC. Maximum allowable fluid temperature in standard pipes produced with commonly used polyester resins is 45 °C. For continuous operation at a temperature between 50 °C and 60 °C it is recommended to consider one higher pressure class; e.g.: use a 10 bar pipe for 6 bars. At higher temperatures other resins with higher thermal resistance and special design are used. Please contact Farassan Company for more information.
