High-Pressure "HP" GRE Offshore Platform & Marine Pipe
Our HP Glass Reinforced Epoxy (GRE) pipes are specifically engineered for marine and offshore platform environments, offering exceptional corrosion resistance, abrasion resistance, and HP durability. With a pressure rating of up to 16 bar, these pipes are specifically designed for firewater systems, ballast piping, and other critical marine and offshore applications, offering a combination of lightweight construction, low cost, superior corrosion resistance, and excellent fire resistance when compared to traditional steel pipes.
Key Features
- Durable Construction: Designed to meet the rigorous demands of offshore and marine applications, with a longer service life compared to steel pipes. Inner Liner Thickness: The 0.5 mm resin-rich liner ensures a durable and smooth interior surface, enhancing the pipe’s overall performance and longevity.
- Lightweight: Simplifies handling and reduces installation costs, unlike traditional steel pipes.
- Hydraulic Performance: Low friction coefficient and no-scale formation inside pipes, leading to improved hydraulic characteristics and better fluid flow.
Corrosion Resistance: Superior performance in harsh marine environments, offering better resistance than steel pipes, particularly in saltwater applications.
Fire Safety: Meets critical fire safety standards for offshore and marine operations, with better fire resistance than conventional steel pipes.
Customisable Conductivity: Conductive versions, with inner conductive veils and filaments, meet higher antistatic requirements, ensuring safe operation in sensitive environments.
Rigorous Testing & Quality Control: Each pipe undergoes hydrostatic pressure testing to meet stringent quality standards. The manufacturing process is controlled by computerized equipment and is certified to ISO 9001 standards, ensuring consistency and reliability.
- Customisable for Marine & Offshore Applications: Our pipes are flexible in diameter, pressure rating, and length, allowing for tailored solutions to meet the specific needs of your marine and offshore operations. Whether used in firewater systems, ballast piping, or other critical offshore applications, these pipes offer optimal performance in demanding marine environments.
