Fibre-Reinforced Plastic (FRP) continues to stand as a revolutionary composite material, combining a polymer matrix fortified with various fibres, commonly known as fibre-reinforced polymer. The selection of fibres, including carbon, glass, basalt, or aramid, and matrix materials such as vinyl ester, polyester, epoxy thermosetting plastics, and at times, phenol formaldehyde resins, showcases the versatility and adaptability of FRP in meeting diverse industrial needs.

Key Features and Advantages of FRP Pipes:

1. Lightweight Construction: FRP pipes, meticulously designed with a composition of 1/10 P.S.C., 1/5 steel, and 1/8 C.I., boast a reduced strength-to-weight ratio compared to alternative materials. This lightweight construction not only facilitates easy handling, installation, modification, and repair but also contributes to cost efficiency.
2. Non-Corrosive Nature: The inherent corrosion resistance of FRP pipes makes them indispensable in applications involving corrosive wastewater and sewage. The effectiveness of their corrosion resistance is contingent upon the overall resin content and the specific resin used in the pipe's laminate. The higher the resin content, the greater the resistance against corrosion.
3. Flexibility in Design and Construction: FRP pipes offer unparalleled flexibility in shaping various equipment pieces or configurations using permanent or temporary molds. This flexibility extends to the construction of ductwork, allowing for the production of different types of transitions, inlets, flanges, and elbows at a minimal expense. Moreover, FRP pipes serve as a suitable option for lining both new and existing structures.

Recent Developments Transforming the FRP Pipe Industry:

1. Innovative Joint Solution by RPS Composites: RPS Composites, based in Franklin, Ohio, has introduced the RPS Grooved Adapter, a robust joint specifically designed for FRP piping systems. This adapter, compatible with the Victaulic Style 296-A coupling, offers a sturdy and dependable joint, particularly in mild corrosive environments such as water, seawater, and wastewater. The standout feature of the Grooved Adapter is its ease of use, allowing for quick coupling or uncoupling without the need for specialized tools or training. Rigorous testing ensures its compliance with ASME NM.2-2020 Proof of Design qualification test standards, including static pressure, cyclic pressure evaluations, and hydrostatic strength testing.
2. Record-Breaking FRP Stack Installation by CPP: Chemical Process Piping (CPP), a company specializing in industrial piping solutions, has marked a significant milestone with the installation of the tallest FRP stack for the Bangladesh-India Friendship Power Company's Flue Gas Desulfurisation (FGD) plant. This 800 ft FRP stack, utilizing vertical winding technology, showcases CPP's innovative approach in the field. Collaborating with BHEL and Simplex in Bangladesh, CPP successfully completed Phase I of the Maitree Super Thermal Power Plant project. This project not only positions CPP as a pioneer in the FRP manufacturing sector but also aligns with environmentally friendly initiatives, leveraging supercritical technology for the thermal power plant.

In conclusion, the global FRP pipe industry is experiencing substantial growth propelled by the construction sector's expansion and the unique advantages offered by FRP pipes. As technological innovations continue to shape the industry landscape, opportunities for remunerative growth, particularly in wastewater management, are poised to drive the market to new heights. The convergence of lightweight construction, non-corrosive properties, and design flexibility positions FRP as a cornerstone in modern industrial applications.
