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.

Why Do You Need The FRP Pipe?

FRP pipe, also called fiberglass reinforced pipe, is a light, high-strength, and corrosion-resistant non-metallic pipe. With its excellent chemical resistance, light weight, high strength, non-scaling, strong shock resistance, long service life compared with ordinary steel pipes and cast iron piping, low overall cost, fast installation, safe and reliable, it is accepted by users. The application fields of fiberglass reinforced pipe involve industries such as petroleum, chemical industry, and sample water.

 

What is FRP (GRP)?

 

 

FRP, another name for GRP, is commonly known as glass reinforced plastic. It is a high performance material formed by mixing fiber material and base material in a certain ratio, which is light and hard, non-conductive, high mechanical strength, and corrosion resistant.

 

What are the characteristics of FRP Pipe?

► 1. The coefficient of development of products is comparable

The coefficient of thermal expansion of the FRP composite product resembles that of concrete. When the ambient temperature level changes, FRP and concrete work in harmony, and also no big temperature level anxiety will certainly be created between them.

► 2. High tensile stamina

The tensile stamina of FRP is considerably more than that of steel, and also the tensile toughness of high-strength steel wire has to do with the exact same, usually 2 to 10 times that of steel.

► 3. Lightweight

FRP product is lightweight and also high toughness, so it can reduce the weight of the framework as well as assist in the construction. Its weight is normally 20% of steel. When it is utilized in a huge span structure, it can substantially lower the weight of the structure.

 

 

► 4. Manufacturing facility production, assembly, and also building

FRP is a fabricated product, which can be made with different toughness indexes, elastic modulus as well as unique efficiency requirements according to the job requirements, such as fiber material of various fiber materials and laying techniques. Factory manufacturing and also on-site installation contribute to making certain tasks top quality, boosting labor efficiency as well as understanding construction automation.

► 5. Rust resistance

FRP material has great corrosion resistance and exhaustion resistance. It can be used in acid, antacids, chlorine salt as well as a moist environment for a long period of time. Thus, the life span of the structure can be boosted. This is hard to compare to the general structure products.

► 6. Practical forming

The manufacturing procedure of FRP consists of pultrusion, winding, hand gluing, injection molding, and also various other techniques. It is not only possible to produce normal shaped FRP products widespread, but likewise to generate nearly approximate designed sheets for creating non-linear structure forms.
