Every year, government spends millions on the maintenance of hydrocarbon pipelines to avoid breakdowns that is usually caused by internal corrosion. But now, with the help of latest techniques and technologies, GRP profiles manufacturers bring several products like GRP pipes in India. These profiles are economically attractive and anti-corrosive in nature. All these material options are being explored by operating companies to lower expenditures for pipeline maintenance activities and this lowers the chances of breakdown and ensures hassle free operations. In this article, we bring the salient features of GRPs along with their benefits and limitations as pipeline material of construction in the industries like oil and gas.
GRPs - The Material Mascot
GRP is a resin plastic that combines fiber and belongs to polymer category. It is commonly known as FRP or fiberglass reinforced plastic. A GRP pipe is a tubular product that contains glass fiber reinforcements embedded in or surrounded by cured thermosetting resin.
Manufacturers of GRP profiles use several varieties of resins and fiber reinforcement materials to fabricate GRP line pipes. Glass fiber material is supreme quality material used in over 90% of all filament or resin GRP manufacturing today. The resins are of different grades and types- polyester resin, vinyl ester resins, phenolic resins, and epoxy resins. Major salient features are:
- Superb corrosion resistance: GRPs are practically immune and resistant to every chemicals (almost) and other fluids used by oil and gas industry, the superb anti-corrosion property of the GRPs to all kinds of hydrocarbon fluids makes it popular materials of construction in gas and oil industry.
- Great strength and light weight: GRP materials are good at mechanical strength and can withstand moderate to extreme pressures during operation. The high strength of GRP pipes make the products easy to handle, easy to transport and installation. Moreover, manufacturers can select resin and fiber accordingly to maximize the service performance.
- Flexibility: The most advantageous thing of GRP is the flexibility it offers. Manufacturers can design numerous profiles in distinct sizes, lengths, and configuration to meet the standards and demands of the customer.
As GRP is anti-corrosive, gas and oil industry use GRP pipes for gases like CO2, H2S, and for salts and chlorides. Practically, GRP material is maintenance free. But, complete ignorance can bring certain maintenance issues.
GRP is still best material and most manufacturers of GRP pipes in India are happy to serve their services and products to the global clients. You can get these profiles from leading manufacturers like Fiber Tech.
