One of the largest use of polymer composites in the country is in the form of GRP/ FRP pipes. What are these and why are these so popular? Let us check out.
What are GRP pipes made of?
GRP or Glass Fiber Reinforced pipes, as the name suggests are generally made from glass fibers. This is the reason these pipes are also known as FRP pipes. GRPpipes are combination of thermosetting plastic (like unsaturated polyester or vinyl ester resins, chopped glass fibers) and reinforcing agents.
Why are The GRP Pipes?
Most often pipes are used to transmit fluids and gas under high pressure. This is the reason whatever pipes you are using must be able to resist the pressure. GRP pipes are highly resistant to surge pressure and has less chances of bursts due to water hammering.
GRP pipes are also used for sewage and potable water transportation; almost 70% of the total number of pipes used in the country are used for these purposes. For these functions these pipes are generally buried underground where the amount of humidity is immensely high, which leads to fast corrosion and hence iron or concrete pipes are not considered appropriate for underground transfer of fluids and gases. Also pipes are often used to transfer corrosive materials like acids and chemicals; GRP pipes are made from epoxy resin and glass fiber, hence resistant to corrosion and best for use for the above mentioned purposes.
These rust free pipes not only run for a long period of time but also ensures less chances of mishaps on the operations floor. As acids and high temperature fluids are passed through the pipes, any leakage can be detrimental. The GRP pipes do not break or leak easily and hence the scope of flow outs is minimal.
As the GRP pipes are strong and durable, there is less wear and tear on these pipes. This also means the pipes need not be replaced on frequent basis. Thus GRP/ FRP pipes can be considered great value for money.Moreover, the inert feature of GRP reduces the need and cost of additional coating and cathodic protection. FRP pipes are characterized by excellent insulation properties, which means you need not even spend on external insulation of these pipes.
This is the reason when the price of crude oil and natural gas increased, manufacturers resorted more to GRP pipes to reduce the overall cost of production.
Along with strength it is also important that the pipes are easy to be carried from one place to another. As compared to iron and concrete pipes, GRP/ FRP pipes are almost 1/5th less in weight.This enables easy installation of pipes with just the use of few hand tools. Top GRP pipe manufacturers in India provide with uniquely designed, light weighed pipes which can be put to any use.
GRP pipes can be used for various applications because these can be customized as per the specific requirements of the customers. The soil conditions are not same everywhere; the amount of gas and fluids to be transported is also not always same, the diameter, pressure class, stiffness, shape and size of the pipe also varies as per the requirement. GRP pipe manufacturers can provide you the pipe you exactly need.
Where can you use GRP Pipes?
The multiple features of GRP/ FRP pipes make these suitable for diverse working environments. These are mostly used at oil drilling units, fire mains, chemical plants, dredging and portable water plants.
GRP pipes are known to last for as long as 50 years. The hydraulic design basis make the pipes reliable and durable. Get some today for your unit and enable a proficient and safe working environment.
