What is CNPS FRP Pipe?
Still battling leaks, rust, and heavyweight steel lines? Swap them out for CNPS FRP Pipe and breathe easy. Our pipe is light to lift yet strong enough for everyday plant pressures. It shrugs off over 3000 aggressive liquids without scaling, so the flow stays smooth. Crews bolt up sections fast, trimming installation labor by up to 40 %. Once in place, it runs clean for five years before you even think about an inspection. That means fewer shutdowns, lower upkeep budgets, and a greener footprint. Free your team to chase production goals, not pipe repairs—choose CNPS and move forward with confidence, starting today.
CNPS Composite Pipe Series
Below are the three best-selling standard models that cover seawater intake, strong-acid transfer, and high-pressure reinjection.
-
DN250 FRP Pipe – Seawater GradeVinyl-ester liner, 150 psi, UV-resistant, handles seawater intake and desalination feed reliably for coastal systems.
-
DN150 FRP Pipe – Acid DutyEpoxy-novolac resin, 300 psi, resists 98 % sulfuric acid; delivered with ANSI-150 flanged ends for chemical transfer.
-
DN100 FRP Pipe – High-PressureHigh-temp vinyl-ester, 450 psi, –30–150 °C range, API 15HR couplings for produced-water reinjection and other high-pressure service.
Performance Highlights of CNPS FRP Pipe
Fiber-reinforced plastic (FRP) pipe fuses high-strength glass fiber with corrosion-resistant resin to give seawater, chemical, and hydrocarbon lines a lighter, longer-lasting, energy-saving upgrade.
Weighs just ⅙ of comparable steel yet handles up to 450 psi. Smaller cranes and supports cut installed cost by 30 %-plus.
Multi-layer resin barrier shrugs off 98 % sulfuric acid, sour gas, and seawater chlorides—no internal liners or periodic recoating required.
Mirror-smooth bore holds Hazen-Williams C = 150. Expect 20 – 30 % lower head loss than steel and downsized pump horsepower.
Standard range –60 °F to 300 °F, 50 – 450 psi; custom vinyl-ester builds survive peaks to 350 °F for extreme duty.
20-ft factory spools with bell-and-spigot adhesive joints let crews finish up to 40 % faster than carbon-steel projects, shrinking downtime.
Engineered to ISO 14692 and ASTM D2996, with optional NSF/ANSI 61 potable-water compliance—ready for one-pass acceptance worldwide.

FRP pipe is a general term. GRE pipe and GRP pipe are both types of FRP pipes. They use different types of resins and are suitable for different application environments.
Compared with steel pipes, FRP pipes are more corrosion-resistant, light in weight, easy to install, and have a long service life.
CNPS has its own full-process quality control program. During the production process, there are quality supervisors following up on the whole process. It has its own laboratory to conduct product inspections and has long-term cooperation with professional third-party inspection agencies to ensure the product qualification rate.
