IFGS intelligent fiber glass solutions for high-pressure GRE line pipe
IFGS (intelligent fiber glass solutions) covers GRP / GRE pipeline products made of glass fiber roving as reinforcement and epoxy resin as the matrix material, molded by winding. This page summarizes the solution scope and links to the published IFGS catalog PDF for fuller product detail—without inventing download counts or extra certifications.
Scope of production published here lists diameter DN40–DN900 and pressure rating 3.45 MPa–34.5 MPa. Product standards cited on the page include API Spec 15HR-2016 High Pressure Glass Fiber Piping Specification and SY/T 6267-2006. Applications stated include oil, gas, and water mixture transport in petroleum, petrochemical, and related areas. Product characteristics listed are corrosion resistance, light weight, long service life, and resistance to easy scaling or waxing.
For acid anhydride GRE line pipe designed as per API 15HR, the page lists medium temperature ≤ 65.5°C, density / specific gravity 1.95 g/cm³ (121.74 lbs/ft³), heat conductivity 0.40 W/m°C (0.23 BTU/ft/hr/°F), coefficient of linear expansion 14×10⁻⁶ mm/°C (6.1×10⁻⁵ in/in/°F), Hazen-Williams factor C = 150, absolute roughness 0.0053 mm (0.00021″), hoop elastic modulus 24.1 GPa (3.5×10⁶ psi), axial elastic modulus 11.9 GPa (1.7×10⁶ psi), and Poisson ratio (minimum) 0.38.

Key applications
- Oil, gas, and water mixture transport lines
- Petroleum and petrochemical GRE / GRP piping programs
- High-pressure glass fiber line pipe per API 15HR (confirm rating)
- Projects needing corrosion-resistant, lightweight non-metallic pipe
What to confirm with CNPS
- Size / rating / medium / standards you need (DN, pressure class, API 15HR or SY/T)
- Temperature and fluid compatibility versus the published GRE parameters
- Jointing, fittings, and documentation requirements
