Glass Fiber Pipe | China Manufacturer for Industrial Fiberglass Piping
As a China based manufacturer, I offer high-quality glass fiber pipe designed for demanding industrial applications. Our glass fiber pipe delivers excellent corrosion resistance, lightweight strength, and stable thermal performance, perfect for chemical, water treatment, and oil & gas piping networks. I know what B2B buyers need: reliable supply, consistent sizes, and prompt after-sales support. That's why our products are manufactured with high-grade ECR glass fibers and resin systems, tested for pressure, temperature, and long service life. We offer standard diameters and custom lengths, with smooth inner surfaces to reduce friction losses. Through strict QC and traceable lot numbers, you can track every batch. We ship from China quickly to global markets, and we can work as your strategic partner, not just a supplier. If you are seeking a dependable glass fiber pipe solution, I provide competitive pricing, short lead times, and technical advice to fit your project requirements. Contact us today to start the collaboration.

We support global logistics, optimized packaging, competitive pricing and responsive after-sales service including installation guidance and spare parts, turning project specifications into durable, cost-effective glass fiber piping solutions.
| Attribute | Specification / Typical Value | Units / Standard | Notes / Common Application |
|---|---|---|---|
| Material System | Glass fiber reinforced polymer (GRP/FRP) with thermosetting polyester or vinylester resin matrix | — | Selection depends on chemical exposure and temperature |
| Manufacturing Method | Filament winding (continuous), centrifugal casting (large diameters), pultrusion for fittings | — | Filament winding common for pressure-rated pipes |
| Nominal Diameter Range | DN 25 up to DN 2400 (1" to 96" equivalent) | mm / inches | Large diameters typically produced by centrifugal or hand-lay methods |
| Pressure Rating (Design) | 0.5 bar up to 25 bar (design-dependent; higher ratings achievable with reinforced layers) | bar / MPa | Verify through hydrostatic testing per project specification |
| Temperature Range (Continuous) | -40 to +95 °C (short-term excursions up to ~120 °C depending on resin) | °C | Vinylester resins improve elevated temperature and chemical resistance |
| Density | Approximately 1.7 – 1.9 g/cm³ (system dependent) | g/cm³ | Lower than many metals — facilitates easier handling |
| Tensile Strength (Composite) | 200 – 600 MPa (fiber-dominated directional property) | MPa | Depends on fiber type, orientation, and resin quality |
| Flexural Strength | 150 – 350 MPa (typical range for common GRP systems) | MPa | Important for buried and externally loaded conditions |
| Modulus of Elasticity (E) | 8 – 18 GPa (directional; longitudinal vs. hoop varies) | GPa | Lower stiffness than steel — support spacing must account for deflection |
| Corrosion & Chemical Resistance | Excellent to acids, alkalis, seawater, many solvents; resistance depends on resin selection | — | Chemical compatibility testing recommended for aggressive services |
| Common Joint Types | Flanged joints, flexible couplings, adhesive/chemical bonding, bell-and-spigot with seals | — | Flanged and mechanical couplings simplify maintenance |
| Typical Service Life | 25 – 50 years (application and maintenance dependent) | years | Life extension with proper inspection and avoidance of incompatible media |
| Fire Performance | Non-metallic — flame retardant additives available; behavior per resin type | — | For enclosed spaces, specify fire-retardant formulations and test reports |
| Standards & Design Codes | Common references: ISO 14692 (GRP piping systems), ASTM D2996 (filament-wound GRP pipe), ASME RTP-1 (RTS equipment) | ISO / ASTM / ASME | Project specification should list mandatory standards and testing |
| Hydrostatic & Factory Testing | Hydrostatic pressure test, visual inspection, dimensional checks, laminate thickness verification | per project standard | Pressure tests typically performed at ≥1.5× design pressure for acceptance |
| Installation: Handling | Use wide slings; avoid point loads and metal-on-composite contact; protect against impact | — | Lightweight nature reduces lifting equipment requirements vs metals |
| Installation: Support & Bedding | Support spacing per design; for buried lines provide uniform bedding and restraint against flotation | — | Account for thermal expansion and deflection limits |
| Inspection & Maintenance | Visual inspection annually; internal inspection or non-destructive testing every 3–7 years depending on service | years | Corrosion monitoring less intensive than metals but chemical exposure requires vigilance |
| Environmental / Sustainability | Long service life and low corrosion losses; recyclability limited (thermoset matrices), energy-efficient transport due to low weight | — | Consider end-of-life plans and recycling streams where available |
| Typical Applications | Seawater piping, desalination, chemical process lines, effluent and wastewater, potable water transmission, HVAC chilled water return | — | Material/resin chosen to match media and operating temperature |
