FRP Mortar Pipe – For Chemical and Water Conveyance

FRP mortar pipe is a high-strength, corrosion-resistant, and lightweight conveying pipeline designed for demanding applications. Constructed with resin as the base material, glass fiber as the reinforcing phase, and quartz sand as the filler, this pipe features a unique structural design. The resin matrix is wound with glass fibers around a rotating mandrel, while quartz sand is evenly distributed as a mortar layer between the fiber layers, forming a composite structure.

This innovative layering ensures an optimal pipe wall architecture, enabling full utilization of material properties. By enhancing stiffness without compromising service strength, it guarantees the stability and reliability of FRP pipes.

With exceptional corrosion resistance, superior hydraulic performance, ease of installation, and short construction cycles, FRP mortar pipes have gained widespread adoption in chemical engineering, drainage systems, and pipeline projects.

Properties of FRP Mortar Pipe​

• High Strength-to-Weight Ratio​

Constructed with glass fiber-reinforced polymer (GFRP) and quartz sand filler, FRP mortar pipes exhibit excellent mechanical strength while remaining lightweight, reducing transportation and installation costs.​

• Superior Corrosion Resistance​

The resin matrix (typically polyester, vinyl ester, or epoxy) provides inherent resistance to chemical corrosion, making it ideal for conveying aggressive media such as acids, alkalis, and saline solutions.​

• Optimal Hydraulic Performance​

Smooth internal surfaces minimize fluid friction, resulting in low head loss and high flow efficiency. The pipe’s non-stick surface also prevents scaling and biofouling, maintaining long-term hydraulic stability.​

• Enhanced Stiffness and Stability​

The sandwich structure—comprising fiber-reinforced layers and a quartz sand mortar core—enhances structural rigidity without compromising flexibility, ensuring resistance to external loads (e.g., soil pressure, live loads) and dimensional stability over time.​

• Easy Installation and Cost Efficiency​

Lightweight design and modular connections (flanged, grooved, or filament-wound joints) enable fast installation, reducing labor and equipment requirements. Its long service life (50+ years) and minimal maintenance further lower lifecycle costs.​

• Design Flexibility​

Customizable dimensions (diameter: 50 mm to 4,000 mm; pressure rating: 0.25 MPa to 2.5 MPa) and material formulations allow adaptation to specific project requirements, including high-pressure or large-diameter applications.​

Applications of FRP Mortar Pipe

FRP mortar pipes combine mechanical robustness, chemical resilience, and installation efficiency, making them a preferred choice for critical infrastructure systems requiring long-term reliability in challenging environments.​

• Chemical Industry​

Transportation of corrosive chemicals, waste liquids, and process fluids in refineries, petrochemical plants, and chemical manufacturing facilities.​

• Water Supply and Drainage​

Potable water distribution, sewage systems, stormwater drainage, and seawater desalination pipelines, leveraging its corrosion resistance and hygiene compliance.​

• Municipal and Industrial Wastewater​

Effluent treatment plants, wastewater recycling systems, and sludge transportation, where resistance to aggressive wastewater components is critical.​

• Power and Energy​

Cooling water pipelines in thermal power plants, cable protection ducts, and offshore wind farm systems, benefiting from its lightweight and durable properties.​

• Oil and Gas​

Subsea pipelines, offshore platforms, and onshore corrosive environments (e.g., sour gas fields), offering superior resistance to chloride-induced corrosion and harsh marine conditions.​

• Irrigation and Agriculture​

Long-distance water conveyance for irrigation systems, resisting soil chemicals and groundwater corrosion to ensure reliable water supply for farmland.​

• Marine and Coastal Engineering​

Seawater intake/outfall pipelines, harbor infrastructure, and coastal protection projects, where saltwater resistance and structural durability are essential.​
