FRP pipes have been widely used in many fields due to their unique performance advantages. The following are their main application areas:

Water supply and drainage engineering field

Urban water supply system: It can be used to transport drinking water. FRP pipes are non-toxic and corrosion-resistant, will not pollute water quality, and have smooth inner walls, which can effectively reduce water flow resistance, reduce energy loss, and improve water supply efficiency. They can replace traditional cast iron pipes and steel pipes, etc., and are widely used in some newly built urban water supply pipeline networks and old water supply pipeline renovation projects.

Urban drainage and sewage treatment system: FRP pipes perform well in both rainwater discharge and sewage collection, transportation and treatment. Its corrosion resistance enables it to withstand acid and alkali components in sewage and various chemical agents, and its good anti-leakage performance can prevent sewage leakage from polluting soil and groundwater. FRP pipes are used in various process pipelines in urban sewage pipe networks and sewage treatment plants (such as aeration pipes, sludge transportation pipes, etc.).

Rural drinking water safety project: When laying drinking water pipelines in rural areas, the installation convenience, corrosion resistance and relatively low maintenance cost advantages of FRP pipes are prominent. They can adapt to the complex terrain and environmental conditions in rural areas and provide a guarantee for safe and stable water supply for rural residents.

Chemical industry

Chemical raw material transportation: In the chemical production process, various corrosive liquids and gas raw materials, such as acids, alkalis, salt solutions and organic solvents, need to be transported. FRP pipes have strong tolerance to these chemicals and can ensure the safe and stable transmission of chemical materials between different production processes and equipment. For example, in chlor-alkali chemical production, pipes used to transport hydrochloric acid, liquid alkali and other materials are often made of FRP.

Chemical reaction device connection pipeline: Pipes connecting various chemical reactors, reactors, separation towers and other equipment need to have good chemical corrosion resistance, high temperature resistance and pressure resistance. FRP pipes can meet these requirements, and can be customized according to specific process requirements. Pipes with different pipe diameters, wall thicknesses and connection methods ensure the smooth operation of the chemical production process.

Chemical Park Public Pipeline Gallery Pipeline: In chemical parks, a variety of pipelines are laid through public pipeline gallery for centralized transportation of chemical raw materials or products required by different enterprises. FRP pipelines have become one of the preferred materials for pipelines for transporting corrosive media in pipeline gallery due to their strong corrosion resistance, long service life and low maintenance cost, which helps to improve the overall safety and reliability of pipeline transportation system in chemical parks.

Power Industry

Circulating Water Cooling System Pipeline: The circulating water cooling system of power plants (including thermal power generation, nuclear power generation, gas power generation, etc.) requires a large number of pipelines to transport cooling water. FRP pipelines have good water resistance, corrosion resistance and high heat exchange efficiency, so that they can work stably in an environment where they are in contact with water for a long time and may have certain water corrosiveness, which can effectively reduce the maintenance cost of the cooling system and improve the operating efficiency of power generation equipment.

Cable protection tube: When laying power cables, protection tubes are needed to prevent the cables from external mechanical damage, chemical corrosion, and electromagnetic interference. The insulation, corrosion resistance, and customizability of FRP pipes (such as pipes with different diameters, lengths, bending angles, etc.) make them ideal cable protection pipe materials, and they are widely used in projects such as urban power grid transformation and substation construction.

Marine engineering field

Desalination system pipelines: In desalination plants, seawater needs to be extracted and pre-treated before desalination. The entire process involves multiple links of pipeline transportation. FRP pipes can resist seawater corrosion and maintain stable performance for a long time in high-salinity, high-humidity marine environments. They can be used to transport seawater and desalinated fresh water to ensure the stable operation of the desalination system.

Offshore oil platform pipelines: Offshore oil extraction platforms need to transport oil, natural gas, production water, and various chemical agents. The environmental conditions are harsh, with both seawater erosion and the presence of flammable and explosive substances such as oil and gas. The corrosion resistance, fire retardancy, light weight and high strength of FRP pipes make them an important part of the offshore oil platform pipeline system, which can reduce the weight of the platform and improve safety.

Agricultural irrigation field

Farmland irrigation pipelines: It can replace traditional cement pipes and metal pipes for farmland irrigation systems. FRP pipes are light in weight, easy to carry and install, and can be flexibly laid according to the layout of farmland. They are also corrosion-resistant and can adapt to the pH of soil in different regions and the water quality of irrigation water. The smooth inner wall can also reduce water flow resistance, improve irrigation efficiency, and reduce irrigation costs. They are especially suitable for large irrigation areas and modern agricultural parks. Greenhouse irrigation and nutrient solution delivery pipelines: In the greenhouses of facility agriculture, irrigation water and prepared nutrient solution need to be delivered. FRP pipes are hygienic and non-toxic, will not have adverse effects on plant growth, and can be customized according to the spatial layout of the greenhouse to meet the irrigation and nutrient solution supply needs under different crop planting modes.

Transportation field

Drainage pipelines for highways and railways: In the construction of highways and railways, a complete drainage system is needed to remove road surface water and ensure the normal use and driving safety of roads. FRP pipes can be used for ditch drainage, underground drainage culverts, etc. Its corrosion resistance, impact resistance and easy installation make it widely used in road drainage projects.

Tunnel ventilation and drainage pipelines: In highway tunnels and railway tunnels, ventilation ducts need to be installed to ensure air circulation, and drainage pipes need to discharge groundwater and leaking rainwater. FRP pipes have become a common choice for ventilation and drainage pipelines in tunnels due to their high strength, good fire resistance (can reach the corresponding fire resistance level according to requirements) and adaptability to complex underground environments.

Food and Beverage Industry

Food raw material delivery pipelines: In food processing enterprises, various food raw materials (such as juice, milk, syrup and other liquid raw materials) need to be delivered. FRP pipes meet food hygiene standards, are non-toxic and tasteless, will not release harmful substances into food, and are easy to clean and disinfect. They can ensure the sanitation and safety of the food production process and are often used for raw material delivery between different processes in food production workshops.

Beverage production line pipelines: Beverage production requires pipeline connections in multiple links from mixing, filtration to filling. The corrosion resistance and smooth inner wall of FRP pipes facilitate rapid and stable fluid delivery and good hygienic performance, making them a commonly used pipe material in the beverage industry, which can effectively ensure the quality and safety of beverage products.
