FRP Pipe for Municipal Water Supply& Agricultural Irrigation

In the field of municipal water supply and agricultural irrigation, traditional metal and plastic pipes often face problems such as corrosion, scaling, and insufficient strength. FRP pipes (fiber reinforced composite pipes) are becoming an ideal choice for modern water supply and irrigation systems due to their high strength, corrosion resistance, and long life. This article will introduce in detail the application advantages, product characteristics, and installation points of FRP pipes in municipal water supply and agricultural underground irrigation.

Advantages of FRP Pipes in municipal water supply

Corrosion Resistance

Resistant to acid, alkali, salt and microbial erosion, suitable for different water quality environments

High strength and lightweight

Excellent pressure resistance, weighing only 1/4 of steel pipes, easy to transport and install

Long life and low maintenance

Service life of more than 50 years, greatly reducing replacement and maintenance costs

Smooth inner wall without scaling

Low water flow resistance, maintaining long-term high flow, reducing pumping energy consumption

Environmentally friendly and non-toxic

Meet drinking water hygiene standards, no risk of heavy metal precipitation

Typical Application Scenarios

Urban tap water transmission network
Sewage treatment plant inlet and outlet pipes
Industrial area water supply system
Seawater desalination water pipeline

Application of FRP pipes in agricultural underground irrigation

🌱 Soil corrosion resistance: Suitable for harsh environments such as saline-alkali land and acidic soil
🌱 Anti-ultraviolet aging: Underground laying is not affected by sunlight and operates stably for a long time
🌱 Anti-clogging design: Smooth inner wall reduces sediment deposition, suitable for drip irrigation and sprinkler irrigation systems
🌱 Economical and efficient: long service life, reducing frequent replacement costs

Typical application scenarios

Field drip irrigation system
Orchard micro-sprinkler irrigation network
Greenhouse water and fertilizer integration system
Saline-alkali land improvement irrigation project

FRP pipe specifications and selection guide

1. Common specifications
Parameters Municipal water supply Agricultural irrigation
Pipe diameter (mm) DN100 – DN2000 DN50 – DN400
Pressure level 0.6MPa – 2.5MPa 0.4MPa – 1.0MPa
Connection method Socket type, flange connection Socket type, quick connection

2. Selection suggestions
Municipal water supply: give priority to high-pressure grade, large-diameter FRP pipes

Agricultural irrigation: choose lightweight, chemically resistant small and medium-diameter pipes

Special environments (such as high-salinity and alkaline land): choose UV-resistant, acid-alkali-resistant reinforced FRP pipes

Key points for FRP pipe installation and maintenance

1. Installation precautions
🔧 Foundation treatment: ensure that the groove is flat to prevent sharp stones from damaging the pipe
🔧 Connection seal: Socket-type needs to be sealed with rubber rings, and flange connections need to tighten bolts evenly
🔧 Backfill requirements: compact in layers to prevent pipes from being compressed and deformed

2. Maintenance suggestions
🔍 Regular inspection: observe whether the joints are leaking and whether the pipes are deformed
🔍 Cleaning management: Municipal water supply pipes can be regularly high-pressure flushed, and agricultural irrigation pipes need to prevent sediment accumulation
🔍 Anti-freeze measures: Insulation or emptying treatment is required in cold areas

High Strength

FRP (glass reinforced plastic) material has high specific strength and weighs only 1/4 of steel, which is easy to transport and install, and has excellent bearing capacity.

Corrosion Resistance

Acid and alkali resistant, salt spray resistant, moisture resistant, suitable for harsh environments such as chemical industry, sewage treatment, and offshore platforms.

Insulation and anti-interference

Non-conductive, suitable for high-voltage power systems to avoid leakage risks. Some models can be equipped with a metal shielding layer to enhance the ability to resist electromagnetic interference (EMI).

Convenient Installation

Modular design supports multiple connection methods such as straight-through, elbow, three-way, and four-way to meet different wiring needs.

Fire retardant performance

Made of flame retardant resin, in line with GB 8624-2012 B1 fire protection standard, effectively delaying the spread of fire and ensuring cable safety.
