GRE (GLASS REINFORCED EPOXY) PIPES

Compare

The GRE PIPES for firewater systems, offshore pipelines, and harsh environments.

Description

Key Features

  1. Corrosion Resistance:
    • GRE pipes are highly resistant to internal and external corrosion, making them suitable for transporting aggressive chemicals, seawater, and other corrosive substances.
    • Unlike metallic pipes, they do not require coatings or cathodic protection, reducing maintenance costs.
  2. High Strength and Durability:
    • Designed to withstand high pressures and mechanical stresses, GRE pipes provide excellent structural integrity even under extreme conditions.
    • Their inherent flexibility allows them to absorb shocks and vibrations without cracking or deforming.
  3. Thermal Resistance:
    • With excellent thermal stability, GRE pipes can operate in a wide temperature range, typically up to 120°C or higher, depending on the resin grade.
  4. Lightweight:
    • GRE pipes are significantly lighter than steel pipes, facilitating easier handling, transportation, and installation, particularly in remote or offshore locations.
  5. Low Hydraulic Friction:
    • The smooth internal surface minimizes pressure drops and prevents scaling or deposition, enhancing flow efficiency and reducing energy costs.
  6. Non-Conductive:
    • GRE pipes are electrically non-conductive, providing safety in applications where electrical insulation is critical.

Applications

  1. Oil and Gas Industry:
    • Widely used in offshore and onshore pipelines for transporting crude oil, natural gas, and production fluids.
    • Ideal for water injection lines, firewater systems, and flowlines due to their corrosion resistance.
  2. Chemical Processing:
    • Used for transporting aggressive chemicals, acids, and solvents in chemical plants.
    • Suitable for storage tank piping, scrubbers, and other critical systems.
  3. Marine and Offshore:
    • Extensively employed in seawater cooling systems, ballast systems, and desalination plants.
    • Resistant to saltwater and marine growth, ensuring long-term performance in harsh marine environments.
  4. Power Generation:
    • Used in cooling water systems, flue gas desulfurization (FGD) systems, and other utility pipelines in power plants.
  5. Water and Wastewater:
    • Suitable for potable water systems, sewage lines, and wastewater treatment applications.
  6. Mining and Industrial:
    • Used for slurry transport, process water pipelines, and other heavy-duty applications in mining and industrial plants.

Specifications

  1. Material Composition:
    • Made from high-strength glass fibers and thermosetting epoxy resins.
    • The combination of materials ensures excellent mechanical, chemical, and thermal properties.
  2. Sizes:
    • Available in diameters ranging from 25 mm to 1000 mm or more, with custom lengths as required.
  3. Pressure Ratings:
    • Designed to handle pressures up to 40 bar or higher, depending on the application and pipe class.
  4. Temperature Range:
    • Typically operates within -50°C to 120°C, with specialized grades for higher temperatures.
  5. Standards and Certifications:
    • Manufactured in accordance with standards such as API 15LR, ISO 14692, and ASTM D2996.

Advantages

  1. Corrosion-Free:
    • Exceptional resistance to both internal and external corrosion eliminates the need for protective coatings or treatments.
  2. Lightweight and Easy Installation:
    • Easier to install and handle than steel pipes, reducing installation time and costs.
  3. Low Maintenance:
    • Requires minimal maintenance due to its resistance to scaling, fouling, and corrosion.
  4. Energy Efficient:
    • Low friction loss and smooth interior surfaces enhance flow efficiency and reduce energy consumption.
  5. Long Service Life:
    • Engineered for durability, with a lifespan of over 20-50 years depending on operating conditions.
  6. Customizable:
    • Can be tailored to specific pressure, temperature, and chemical resistance requirements.
