The application and use of underground large-diameter composite pipe have continued to grow since the mid to late 1980s. Technological advances in fiber winding processes, corrosion resistance, education and promotion, and strong market forces have contributed to the popularity of fiberglass pipes.
Applications of FRP pipes
The use of FRP piping is increasing day by day due to its high durability, corrosion resistance and moderate strength.FRP piping systems are used in various industries, such as
Drinking water and desalination industries
Chemical, petrochemical, oil and gas industries.
Piping and ventilation ducts
Irrigation and sanitation services
Water distribution and transmission
Slurry pipelines
Power plants, etc.
Performance of FRP Pipes
The key properties that make FRP Pipes ideal for various industries around the world are
Excellent corrosion resistance
Excellent strength-to-weight ratio. Note that FRP pipes have a higher strength-to-weight ratio than steel or other metal pipes.
Lightweight for easy handling and transportation.
Dimensional stability
Non-toxic
Low coefficient of friction (>25% better than steel) ensures excellent flow characteristics
Good abrasion resistance
Suitable for above-ground and buried pipes
Resistant to biological attacks such as bacteria
Non-conductive and non-electrically conductive
Low maintenance costs
1、Corrosion resistance
FRP pipes have inherent corrosion resistance. In most cases, fiberglass-reinforced plastics are the only materials that can handle certain service environments. In addition, their corrosion resistance is usually combined with their cost advantage, making them the most acceptable solution. The corrosion resistance of glass fiber reinforced plastic pipes is a function of the total resin content and the resin used in the pipe laminate. Therefore, higher resin content means higher corrosion resistance.
2、Weight advantage
The low weight to strength ratio of FRP pipe is another significant advantage of FRP pipe. For the same strength, fiberglass reinforced plastic pipe is about half the weight of aluminum and one-seventh that of stainless steel.
Lightweight properties are critical, especially when considering the ease and cost of installing a piping system. The inherent lightweight of FRP pipe is a major advantage when equipment must be installed over existing structures such as roofs or laminated scrubbers.
3. Excellent Strength
The high strength of FRP pipe plays an important role in the design of various FRP equipment and in applications such as pultruded profiles. In addition, the combination of high strength and lightweight properties make FRP pipes suitable for fiber-wound ducts and pipes.
4. Economical
Lower cost is a major advantage of using FRP piping, as they provide an effective corrosion solution at the lowest cost compared to materials such as titanium, rubber lining and stainless steel. However, the cost advantages of such materials depend largely on design considerations, application, pressures involved, availability, raw material costs and product configuration.
5. Flexibility
FRP pipe is versatile in its application but is often overlooked. However, it is important to note that you can use FRP pipe to do things that cannot be done efficiently and economically with other off-the-shelf materials. FRP pipe can be used to mold any equipment or configuration where permanent or temporary molds can be constructed. For example, piping work with FRP pipe is easy because you can make all types of tee inlets, rectangular transitions, round transitions, elbows and flanges at a minimal cost. Glass fiber reinforced plastic pipe can also be used to line new and existing structures.
The design of FRP systems has been greatly improved through the use of computer software programs. These programs include, among other things; chemical composition, gas flow analysis, liquid flow analysis, thrust block analysis, free-span analysis and installation information. This was important to ensure that the specific requirements of the different industries were fully met to ensure maximum efficiency of the FRP piping.
