    • High-performance FRP pipes - ideal for seawater and freshwater projects

    Provide lightweight, long-life, low-maintenance pipe systems for your marine projects

    Why choose FRP pipes to meet seawater challenges?
    In the fields of seawater transportation, desalination and marine engineering, traditional metal pipes often require frequent maintenance, shortened life and soaring costs due to salt spray corrosion, chemical erosion and microbial attachment. FRP pipes are becoming the preferred solution for global engineering projects with their excellent corrosion resistance, high-strength lightweight design and ultra-long service life!

    The core advantages of FRP pipes in seawater environment

    1. Extremely corrosion-resistant, no fear of seawater erosion
      FRP pipes use resin-based composite materials to completely eliminate electrochemical corrosion problems, easily deal with chloride ions, sulfates and acid-base media in seawater, and have a service life of more than 50 years, far exceeding metal and concrete pipes.
    2. Lightweight design, installation efficiency increased by 40%
      The weight is only 1/4 of that of steel pipes, and the transportation and installation costs are greatly reduced. It is especially suitable for complex terrains such as offshore platforms and cross-sea pipelines, which significantly shortens the construction period.
    3. Smooth inner wall, energy consumption and maintenance costs are reduced
      The friction coefficient is low (Hasen-Williams coefficient ≤ 150), maintaining high flow efficiency for a long time, reducing pumping energy consumption; anti-microbial adhesion properties reduce clogging, and operation and maintenance costs are saved by 30%+.
    4. Customized engineering adaptation capabilities
      Supports customization of pipe diameters from DN50 to DN4000, with a pressure range of 0.25MPa to 6.4MPa, meeting the full-scenario needs of seawater intake, high-pressure reverse osmosis (RO) systems, and concentrated brine discharge.

    Typical application scenarios

    ✅ Desalination plant: corrosion-resistant pipeline system for the entire process from water intake to pretreatment, high-pressure pumping, and desalinated water transportation.
    ✅ Offshore oil and gas platform: high-reliability pipeline network for seawater cooling, fire water, and wastewater discharge.
    ✅ Coastal power stations and chemical plants: resist the harsh corrosive environment of seawater circulation cooling systems.
    ✅ Island municipal infrastructure: lightweight design reduces the difficulty of cross-sea construction and ensures stable transportation of freshwater resources.

    Technical Specifications of FRP Pipe for STP/ETP Projects

    Full coverage of specification parameters, flexible adaptation to engineering needs

    Pipe diameter range: DN50 to DN4000 (supports non-standard customization)

    Length customization: standard single pipe length 6m/9m/12m, can customize extra-long pipe sections to reduce joints

    Pressure level: 0.25MPa to 6.4MPa (covering low-pressure seawater intake to high-pressure RO system)

    Temperature range: -40°C to +120°C (meeting the alternating conditions of hot and cold seawater)

    Installation Best Practices

    Installation and maintenance guide: fast deployment, worry-free operation and maintenance
    ✅ Efficient installation

    Lightweight lifting: no heavy machinery is required, and manpower can complete the handling and docking of pipe sections

    Diversified connections: support socket joints, flange connections, clamp quick installation and other methods, adapting to complex environments such as offshore and underground

    Anti-deformation design: high ring stiffness (SN2500 to SN10000) ensures that it will not deform when buried on the seabed or laid overhead

    ✅ Intelligent maintenance

    Zero corrosion and protection-free: no need to regularly apply anti-corrosion layer or sacrificial anode protection like metal pipes

    Quick maintenance: local damage can be cut and repaired on site without replacing the entire pipe

    Monitoring compatibility: leakage detection system can be integrated to monitor the health status of the pipeline in real time

    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.

    Long Life

    Compared with traditional metal cable trays (such as galvanized steel and aluminum alloy), it has a longer service life and lower maintenance costs.
