Fiberglass Engineering
Comprehensive Fiberglass Engineering
Piping from Fiber Reinforced Plastics (FRP) has been used in the oil and gas industry since the early sixties. Korean Techno Inspection Engineers have been involved in the development and introduction of FRP from the onset, offering a unique portfolio dedicated to the design of piping systems including Fiberglass systems.
Pipeline Integrity & GRE
Glass Reinforced Epoxy (GRE) pipes are a valid alternative to carbon steel, especially for corrosive, aggressive, and normal environments. They are lightweight, maintenance-free, and offer high mechanical, thermal, and chemical resistance.
We offer consultancy service for life extension with Pipeline Integrity Management support (PIMS) and Fit for Purpose (FFP) analysis for existing assets.
Fibre Glass Systems & Capacity
GRE pipe technology is based on the continuous Filament Winding process. Mechanical and physical properties are conducted as per ASTM and other testing standards. Epoxies offer relatively high stiffness and strength, making them a better choice for fabricating pipes.
Manufacturing Excellence
Pipes are wound on precisely machined steel mandrels and cured up to 180°C. Modulus of Elasticity of FRP products is 10-20 times less than traditional metallic pipes, providing unique flexibility.
Fire Endurance & Thermal Capacity
Fire retardant FRP products can withstand up to 900°C for 30 minutes. Melting point of glass is very high, allowing it to maintain structural integrity. Thermal expansion of fiberglass is at most 1.8 times that of Carbon Steel, far less than commonly thought.
Material Limitations & Resins
Selecting the right resin system is critical for specific chemical environments and temperature profiles.
| GRP Type | Resin Cure System | Design Temp (Max) |
|---|---|---|
| Glass-fibre/epoxy (GRE) | Aromatic / Cyclo-aliphatic / Aliphatic | 100°C - 115°C |
| Glass-fibre/vinyl ester (GRV) | Bisphenol A | 90°C - 140°C |
| Glass-fibre/polyester (GRP) | Isophthalic | 60°C - 90°C |
