| Application Sector / System Type | Typical GRP Pipe Types & Key Features | Key Applicable Standards & Specifications |
|---|---|---|
|
Water Transmission & Distribution
(Potable water mains, raw water, irrigation) |
Centrifugally Cast (CC) or Filament Wound (FW), High-Stiffness Classes, Food-Grade Resin Liner (typically isophthalic or vinyl ester). Key: Corrosion-free, low hydraulic roughness (Hazen-Williams C=150), lightweight. |
Product/Design:
Health: NSF/ANSI 61, WRAS, KIWA |
|
Sewer & Drainage (Gravity & Pressure)
(Wastewater force mains, gravity sewers, stormwater) |
High-Stiffness (SN 2500 to SN 10000 N/m²), Abrasion-resistant liner, Corrosion-resistant resin systems (vinyl ester/bisphenol). Key: Excellent corrosion resistance to H₂S and chemicals, smooth bore. |
Product/Design:
|
|
Oil & Gas (Onshore & Offshore)
(Produced water, injection lines, firewater, low-pressure flowlines) |
High-Pressure Filament Wound pipes, API 15HR certified, Fire-Retardant resins, Conductive layers for grounding. Key: Internal/external corrosion resistance, subsea capability. |
Product/Design:
|
|
Chemical & Industrial Process
(Chemical effluent, brine lines, acid waste, FGD systems) |
Corrosion Barrier construction (C-glass veil + resin-rich liner), Special resin grades (vinyl ester, furan, epoxy), High temperature rating. Key: Custom engineering for specific chemical/temperature service. |
Product/Design:
|
|
Power Plant & Desalination
(Cooling water intake/outfall, seawater lines, demineralized water) |
Large Diameter (up to 4000mm), Marine-Grade resins, Abrasion-resistant liners for sandy water, Dual laminate options. Key: Superior seawater corrosion resistance vs. steel, long service life. |
Product/Design:
|
|
Marine & Offshore
(Seawater cooling, ballast, firewater on platforms, shipbuilding) |
Lloyd's/DNV approved, Fire-Rated systems, Impact-resistant, Conductive layers for static dissipation. Key: Lightweight advantage offshore, non-conductive. |
Product/Design:
|
|
Mining & Slurry Transport
(Tailings lines, process water, aggressive mine drainage) |
Heavy-Duty Abrasion-Resistant liners (ceramic-filled, polyurethane), Extra wall thickness, High stiffness. Key: Superior abrasion-corrosion resistance vs. steel in slurry service. |
