The main reasons for the increased use and popularity of fiberglass are key benefits such as high strength-to-weight ratio, dimensional stability, good mechanical properties, ease of installation, reduced installation costs, lower maintenance costs, and overall durability under extreme conditions. Likewise, another advantage of fiberglass tubing over traditional construction materials is its smoother inner surface. This characteristic, with its smooth inner bore, resists scale deposits and can produce greater service fluid flow throughout the life of the project.

 

What is FRP pipe?

The complete form of FRP is glass fiber reinforced plastic, which is a composite material consisting of a fiber-reinforced polymer matrix. Thus, FRP pipe is a pipe manufactured from FRP material by contact molding or fiber winding methods. Various types of resins, such as thermosetting polyesters, epoxy resins, phenolic resins, etc., are used to obtain specific FRP pipe properties in the final product. The most widely used reinforcement material is glass fiber "E-glass". FRP piping systems are used worldwide as a corrosion resistant alternative to metal piping. FRP piping systems are available in a variety of sizes, ranging from 1" to 144".

 

FRP pipe is manufactured by a winding process that reinforces thermosetting epoxy resins with continuous glass filaments. As the resins cure, they undergo an irreversible chemical reaction, giving them excellent resistance to temperature changes, while the glass fibers give them excellent mechanical strength. In microtunnels, steel casing is used for jacking where significant force is required. frp pipe is now widely used for this purpose because of the reduced force of hydraulic jacks, making it cost effective and also allowing longer lengths to be installed. frp can also be used for non-excavation repair methods such as slip lining. frp is resistant to corrosion and chemicals, making it an ideal material for pipes carrying such wastewater.

 

Classification of FRP pipes

According to the shape of media, FRP vessels can be divided into three categories of liquid, gas, solid tank; according to the pressure grade,can be divided into two categories of ATM tank and pressure tank; According to shape of vessel, can be divided into three categories of horizontal cylinder tank, vertical cylinder tank, rectangle tank; And PVC/FRP, PP/FRP, PVDF/FRP composite tanks.

 

Applications of FRP pipes

The use of FRP piping is increasing due to its high durability, corrosion resistance and moderate strength.FRP piping systems are used in various industries, such as

Drinking water and seawater desalination industries

Chemical, petrochemical, oil and gas industries.

Piping and ventilation ducts

Irrigation and sanitation services

Water distribution and delivery

Slurry piping

Power plants, etc.

How FRP Pipe is Constructed?

 

 

Three different processes are commonly used to fabricate fiber reinforced plastic pipe: centrifugal casting, filament winding, and hand lay-up. Filament winding and centrifugal casting are used to make pipe up to approximately 12 inches in diameter, with filament winding being the most common. Hand lay-up is generally used for larger diameter pipes, and for asymmetric shapes.

 

Centrifugal Casting

The centrifugal casting process involves layering glass cloth on the inside walls of a tubular mold which is rotated at high speed. Catalyzed liquid resin is then injected into the rotating mold. Centrifugal force ensures that the reinforcing fibers are thoroughly saturated with resin and serves to drive out air bubbles that might compromise the physical properties of the pipe. The mold continues to rotate while the resin cures.

 

Filament Winding

In filament winding, continuous fiberglass filaments, called rovings, are saturated with catalyzed liquid resin and helically wound around polished steel mandrels. Typically, the fibers are fed through a mechanical device that moves up and down the length of the rotating mandrels. The resin is then cured at elevated temperatures and the finished pipe is removed from the mandrel.

Filament winding results in the highest fiber-to-resin ratio of the three fabrication methods and consequently offers the highest strength-to-weight ratio. This is the method used by Waco Boom.

 

 

Hand Lay-up

As the name suggests, hand lay-up is a manual fabrication process. It involves building up layers of chopped glass or woven glass mat impregnated with catalyzed resin around a suitable mold. Special metal rollers are used to improve glass wet-out and force out trapped air bubbles. Hand lay-up is generally used only for custom shapes or for large-diameter pipe where filament winding or centrifugal casting is not practical.

What is the difference between FRP and GRP?

FRP stands for Fiber Reinforced Plastic, a term commonly used in North America in the U.S. GRP is a term that means the same thing. However, it is commonly used in Europe and Asia to stand for glass fiber reinforced plastic.

 

What is fiber reinforced plastic/polymer (FRP)?

 

Fiber reinforced polymers consist of two main components; fibers and a polymer matrix. In FRP, the fibers are embedded in a polymer matrix. This structure provides chemical and physical properties that are completely different from the properties of the individual materials. In fact, these materials meet higher engineering requirements than ordinary materials. As a result, composites are used in less sophisticated very complex and demanding manufacturing tasks. The mechanical, civil, biomedical, marine and aerospace industries are the main users of composites.

 

The main role of fibers is to provide strength and stiffness to the material. However, the fibers alone are brittle (e.g., glass). Therefore, fibers are encapsulated in a polymer material coating. The polymer matrix holds the fibers in their position and transfers the load between the fibers. It also contributes to the interlaminar shear strength.

 

The following fibers are used in composites: E glass, S glass, quartz, aramid (Kevlar 49), Spectra 1000, carbon (AS4), carbon (IM-7), graphite (P-100) and boron. Polyester, vinyl ester, epoxy, bismaleimide, polyimide, and phenolic resins are the polymers used. Each polymer has different chemical and physical properties; therefore, contributes differently to the composite structure. As a result, the properties of the composites also vary from polymer to polymer.

 

Polyester and vinyl are low-cost materials and are therefore widely used in commercial applications. Epoxy resins are used in high-performance continuous fiber matrices. It also outperforms vinyl and polyester under high temperature conditions. Bismaleimide and polyimide are high temperature resin matrices used in temperature critical engineering applications. Phenolic resins are high-temperature resin systems with good smoke and fire resistance; therefore, they are used in aircraft interiors.

What is Glass Reinforced Plastic (GRP) / Glass Fiber Reinforced Plastic (GFRP)?

 

Glass Reinforced Plastic, commonly known as fiberglass, is a fiber reinforced polymer that contains glass fibers in a composite structure. The polymer is usually epoxy, polyester or vinyl. Fiberglass materials are commonly used in high performance recreational aircraft and gliders, boats, automobiles, bathtubs, hot tubs, water tanks, roofing products, pipes, cladding, castings, surfboards, and exterior door skins.
