In this article, we&#;ll highlight the basic facts and numerous benefits they offer for industrial applications.

What is FRP?

FRP, or Fibre-Reinforced Plastic, is a composite material made of a polymer matrix reinforced with fibres such as glass or carbon.

This unique combination results in a material that is lightweight yet incredibly strong and durable.

FRP is fully customizable, making it the preferred choice for pipes that require less maintenance over time and protect the environment.

The Benefits of FRP Pipes

Corrosion Resistance: One of the most significant advantages of FRP pipes is their exceptional corrosion resistance. Unlike traditional materials like steel or concrete, FRP is impervious to rust, making it ideal for corrosive environments such as chemical processing plants or wastewater treatment facilities.

Lightweight: FRP pipes are significantly lighter than metal pipes, making them easier to transport, handle, and install. This can lead to cost savings in terms of labor and equipment required for installation.

High Strength-to-Weight Ratio: Despite being lightweight, FRP offers excellent strength and durability. Products made with it can withstand high pressures and loads, making it suitable for a wide range of applications, including industrial piping, water distribution, and sewage systems.

Longevity: FRP provides a long service life and requires minimal maintenance compared to traditional materials. Products made with it are resistant to degradation from UV exposure, chemicals, and abrasion, ensuring reliable performance over time.

Versatility: These pipes can be customized to meet specific project requirements, including diameter, length, and thickness. They can be in various configurations, including straight pipes, elbows, tees, and reducers, making them suitable for diverse applications.

Possible Applications of FRP Pipes

Chemical Processing: FRP is commonly used in chemical processing plants, where resistance to corrosive chemicals is essential.

Water and Wastewater: FRP pipes are great for water distribution, sewage systems, and stormwater drainage.

Oil and Gas: These pipes can be used in oil and gas production facilities for transporting fluids and gases.

Fiberglass Reinforced Plastics (FRP)

FRP vs GRP: Difference Between FRP and GRP

FRP stands for Fiber Reinforced Plastic while GRP stands for Glass Reinforced Plastic. The name makes it clear that there is a change in the reinforcing fiber. But both FRP and GRP are normally used to denote the same plastic products.

Introduction

In recent years, FRP has been widely used in process, water and chemical industries due to their high resistance to corrosion.

FRP pipes are also increasingly used for the transport of Water, Oil, Fuel, Glycol, Wastewater, Sewer, etc. As a result, the demand for FRP pipes is continuously increasing.

The service life is usually very high, in the range of 50 years. Thus, the total cost of FRP pipes for life becomes cheaper as compared to metal pipes.

What is FRP?

The full form of FRP is a composite material consisting of a polymer matrix reinforced with fibers. So, an FRP pipe is a pipe manufactured of FRP material by contact molding or filament winding method. Various types of resins like thermosetting polyester, epoxy, phenolic resin, etc are used to get specific FRP pipe properties in the final product.

The most widely used reinforcement is the fiberglass. As a corrosion-resistant alternative to metallic piping, the FRP piping system has found worldwide application.

Common Fibers include:

• Glass is a very good insulating material and, when blended with the matrix, forms fiberglass or glass reinforced plastic. Compared to carbon fiber, it is both less strong and rigid and less brittle and expensive.
• Carbon based fiber reinforced plastics offer high tensile strength, chemical resistance, stiffness, and temperature tolerance along with low thermal expansion and weight. The carbon atoms form crystals which lie mostly along the fiber&#;s long axis. This alignment makes the material strong by making the ratio of strength to volume high.
• Aramid is a fiber component that results in robust and heat-resistant synthetic fibers. It finds wide applications in many industries.

FRP Flanged Fittings

By selecting FRP as the pipe and fittings materials, include flanges, elbows, tee's, crosses, reducers etc., the need for internal lining, external coating, and cathodic protection can easily be eliminated. FRP piping system is available in a wide range of sizes starting from 1 inch to above 100 inches.

More than just FRP pipe systems

Besides pipelines, storage tanks, towers, grids on walkways, profiles (like steel profiles) etc. are also manufactured from FRP. Below a description of a storage tank

Introduction

FRP storage tanks are divided into vertical storage tanks and horizontal storage tanks. The winding material selection of storage tanks must be appropriate, quality priority, and price consideration.

In the actual production, the tank wall structure of the FRP-wound storage tank is generally an inner liner layer, a strength layer and an outer surface layer.

Material and resin selection

Due to the different functions of the layers, the materials are selected differently, and the inner liner is directly in contact with the medium, and the material selection is correct or not, which plays a key role in controlling the leakage of the wound storage tank.

To use vinyl resin if store acidic medium, to use bisphenol A resin if store alkali medium, to use alkali-free glass fiber if need to be water and alkali resistant, to use medium-alkali glass fiber if need to be acid-resistant , and the inner liner is made of surface felt and chopped together to reinforce to increase the amount of glue and enhance the impermeability.

The strength layer mainly meets the strength and stiffness requirements of the storage tank. Material selection should fully consider that the selected resin matrix must have good penetrability with the glass fiber for winding to form a dense structural layer; the outer surface is in direct contact with the external environment, and the material is selected according to the aging resistance requirement.

Application:

FRP tanks can be used to store tanks of various media. They are resistant to pressure, corrosion, ageing, long service life, light weight, high strength, impermeability, heat insulation, insulation, non-toxicity and smooth surface. It is widely used in coatings, pharmaceuticals, building materials, chemicals, pigments, resins, food, scientific research and other industries.

Drawbacks of FRP

• FRP is not recommended for carrying fluid with temperature more than 100 degrees celsius
• Slight degradation from UV rays is found to occur which can be reduced by using pigments, dyes, UV stabilizers, fillers, etc in the resin system
