Corrosion-Resistant FRP Piping That Outlasts Steel
80% lighter than carbon steel, service-ready to 93.3 °C with a 25-year design lifecycle — engineered as a complete piping system, not just a pipe.
Product Overview
FRP (fiber-reinforced plastic) pipe fuses high-strength glass fiber with corrosion-resistant resin to deliver a pressure-rated piping solution that will not rust. FRP is the umbrella material family: GRE and GRP pipe are both types of FRP pipe that use different resin systems to match different service environments. The result is a single material platform that can be tuned for seawater, sour gas, strong acids or produced water.
The operating envelope is engineered for demanding duty: continuous service up to 93.3 °C, a standard pressure range of 50–450 psi, and a 25-year lifecycle verified through ASTM D2992 testing (as stated in our design documentation). At about 80% of the weight of carbon steel — roughly one-sixth — FRP cuts crane size, support load and installation time, while the mirror-smooth liner (≤ 0.10 µm roughness) boosts flow by 12% and keeps pumping energy low.
CNPS delivers FRP as a complete system: pipe, joints, flanges and fittings engineered together. Custom diameters from 25 mm to 1200 mm, UV-resistant outer coatings and builds designed to ISO 14692 and ASTM D2996, with optional NSF/ANSI 61 potable-water compliance (engineered to, not certified).
Why Choose FRP Pipes?
- Carbon steel corrodes in chlorides, sour gas and strong acids, forcing coatings, liners and frequent replacement
- Heavy pipe demands large cranes, heavy supports and long, costly installation campaigns
- Rough or scaled bores raise pumping energy and reduce flow capacity over time
- Project teams need a pipe supplier who can size, rate and document the full system
CNPS Solution: A multi-layer resin-barrier FRP system with lightweight 20-ft factory spools, bell-and-spigot adhesive joints and a mirror-smooth bore — engineered to ISO 14692 and ASTM D2996, with custom diameters from 25 mm to 1200 mm.
- Installed cost typically cut by 30%+ through smaller cranes and lighter supports
- 20–30% lower head loss than steel keeps pumping energy and operating cost down
- Crews can finish installation up to 40% faster than carbon-steel projects
- No internal liners, no periodic recoating — a 25-year design lifecycle
- Flow boosted by 12% via the ≤ 0.10 µm liner finish
- Diameters: custom, 25 mm – 1200 mm
- Pressure: standard 50 – 450 psi
- Temperature: −60 °F to 300 °F standard; custom vinyl-ester builds to 350 °F
- Lengths: 20-ft factory spools with bell-and-spigot adhesive jointing
- DN250 seawater-grade model — vinyl-ester liner, 150 psi, UV-resistant (seawater intake / desalination feed)
- DN150 acid-duty model — epoxy-novolac resin, 300 psi, resists 98% sulfuric acid, ANSI-150 flanged ends
- DN100 high-pressure model — high-temp vinyl-ester, 450 psi, −30 °C to 150 °C, API 15HR couplings
- Lightweight strength — Weighs about 1/6 of comparable steel yet handles up to 450 psi; smaller cranes and lighter supports cut installed cost by 30%+.
- Total corrosion resistance — Multi-layer resin barrier resists 98% sulfuric acid, sour gas and seawater chlorides; no internal liners or periodic recoating required.
- Ultra-smooth flow — Mirror-smooth bore holds Hazen-Williams C = 150; expect 20–30% lower head loss than steel.
- Broad pressure and temperature window — Standard range −60 °F to 300 °F at 50–450 psi; custom vinyl-ester builds survive peaks to 350 °F.
- Fast installation — 20-ft factory spools with bell-and-spigot adhesive joints let crews finish up to 40% faster than carbon-steel projects.
- Designed to international standards — Engineered to ISO 14692 and ASTM D2996, with optional NSF/ANSI 61 potable-water compliance (engineered to, not certified).
- Proven production backbone — 16 years of ISO 9001-certified FRP pipe production passing API and ASTM tests, custom prototypes in 14 days, and support hubs in the Middle East and Europe.
