Types and Classificationsof Faratec™ FRP Pipe


In general, FRP pipes are most known as light, chemical resistant, erosion and corrosion free pipes with smooth inner skin and constant roughness factor during its life pot of more than 50 years and also mostly maintenance free. FRP pipes as a composite and alterable product can be designed and manufactured to satisfactory suitable for any kind of soil condition as well as all kind of fluids. In basic alteration of such products changing the employed resin would result Glass Reinforced Polyester pipes (GRP), Glass Reinforced Vinyl ester pipe (GRV), Glass Reinforced Vinyl ester Epoxy pipe (GRVE) and Glass Reinforced Epoxy (GRE). Respectively, mentioned pipe types resistance to chemical environments would increase so GRP pipes are suggested for raw/potable water, surface water gathering, industrial/normal swage gathering and transmission and so on, while GRVE is normally proposed for sea water transmission, sever chemical conditions of industrial waste/swage gathering, oil condensate and etc. and GRE pipes are suggested for very sever chemical conditions such as crude oil and petroleum. Shall be kept in mind that, apart from said beneficiary and unique advantages, FRP pipes are very competitive pipe in comparison with other pipe materials from pricing point of view. Aforementioned types of FRP pipes can be classified and manufactured as follows:


1-Uni-Axial Pipes



Well known generation of FRP pipe is the first generation of its kind, which is so called Uni-Axial pipe, and is most suitable pipe for underground installation. The main reason for naming them Uni-Axial is requirement of detailed installation (bedding, initial backfilling and final backfilling) ensuring to form a soil-pipe mechanism. Uni-Axial pipes although having a great and strong hoop performance against external and internal load in pipe structure, resisting and transferring thrust forces and stresses at joints requires adequate support which normally and traditionally provided by concrete structures called thrust blocks. Thrust blocks are designed according to pipeline’s internal pressure to fulfill requirements of whole pipeline to stand both external and internal loads such as traffic loads and water hammer loads respectively. However, there are practiced ways and options to optimize project’s budget and time by using Uni-Axial pipes in combination with the following class of pipes to eliminate concrete works while having proper outcome. In brief, Uni-Axial or first generation of FRP pipes are designed and manufactured:




• To resist both external and internal loads using soil-pipe mechanism
• For all underground installation purposes including fluid transmission and energy tunnels,
• As the most economically optimized pipes
• And used with flexible jointing system

2-Bi-Axial Pipe



Increasing demands for industrial use of FRP pipes through its inevitable beneficial properties such as light weight, chemical and environmental resistance, erosion and corrosion freeness, mostly maintenance free and etc. brought Faratec™ a challenging task of designing second FRP pipe generation that not only needs to have all tailoring properties and good performance under internal and external load but also is supposed to be installed over ground. This means new demands are toward a FRP pipe that shall stand all loads with no support from soil-pipe mechanism. In other words requirement was to create a semi-steel pipe in terms of mechanical properties with entire advantageous properties of FRP pipe. Faratec™ came up with Bi-Axial pipe that provides mechanical properties off our times higher than steel pipe in hoop direction and mostly similar strength in axial direction. Bi-Axial pipes can simply be installed over ground and on pipe racks indicating the same performance as steel pipes. This class of Faratec™ FRP pipe is most suitable for complex industrial purposes. Not specific requirement for soil condition has made this class of pipe suitable for underground installation where the surrounding soil is very poor in bearing capacity or muddy, swampy and weak soil or even where ever traffic loads become more than Uni-Axial pipe capacity. Summarizing Bi-Axial FRP pipes of Faratec™specification, this class of pipe is designed and manufactured:




• For both underground and aboveground installation
• To resist impact loads such as water hammer and vacuum
• And used with fixed/rigid jointing systems

3- Jacking Pipe



Faratec™has developed a class of prefabricated pipe that specifically designed to be installed using hydraulic jacks for trenchless applications;suitable for pipelines which are to be installed in a busy road with no possibility of open-trench installation, or places that pipeline crosses railway, highways, existing water channels, structures’ foundation and etc. Unlike other jacking pipes, Faratec™Jacking Pipes works as transmitting pipe and resist any soil condition while other jacking pipe materials requires a separate sleeve.
In brief Faratec™ Jacking Pipes are designed and manufactured:




• In pressure classes of 1 to 32 bars, upper pressure classes are available upon request
• In diameter ranges of 25 to 3000 millimeters
•  In stiffness classes of 25000 to over 200000 Pa
•  Working temperature of 160 dg of centigrade
• To be jacked by force of up to 700 tones.
•To resist impact loads such as water hammer and vacuum
•Trenchless application
•And used with flexible and fixed jointing systems

4 - Anti Static - Pipe



Conductivity of a pipe provides great benefit when it comes to transferring combustible and flammable fluid. Faratec™ found a solution to decrease the risk of potential explosion and fire caused by built-up electricity in pipe-wall from combustible and volatile fluids running through pipelines. Anti Static pipe safely usable for such mentioned fluids as easily conducts electricity.

5- Fire Retardant - Pipe



This class of pipe can withstand external fire temperature of up to 1100 degree of centigrade from direct propane flame. Transferred heat to inside running fluid is less than 15 dg of centigrade. This class of Faratec™ pipe is most suitable for over/under ground onshore/offshore firefighting pipelines. This pipe is manufactured and been satisfactory installed in several onshore oil plants.

6- Anti UV - Pipe


Although the radiation wavelength of sun ray have no effect on the overall mechanical properties of GRP pipes, the use of Anti UV pipes is recommended, when pipes are exposed to sun-rays for prolonged period of time (above ground installation or when the pipes are stored outdoor before installed).

7- Abrasion Resistant - Pipe



Suspended particles in fluids have always been one of clients’ concerns because particles, which unavoidably are to be carried by fluids through pipelines, can damage pipes, which severely effects whole pipeline performance during operation period. Pipe’s inner face erosion results local failures and so increases maintenance cost and also by reducing inner wall smoothness imposes a massive change in hydraulic properties of fluid inside the pipeline that cause unwanted and unexpected forces to all pipeline facilities such as pumps. All these damages reduce the entire project’s life expectancy. To solve issues rose by suspended particles in pipelines Faratec™ introduces Abrasion free pipes, which resist erosive particles in fluid. This class of pipe designed for mine industry and also can be used for other purposes.
