The application of GRE (Glass Reinforced Epoxy/ Fiber Reinforced Plastic) piping in ship piping systems, particularly in scrubber systems, is a highly important and growing field.

Key Advantages of GRE Piping

• Resistance to Strong Acids and Chlorides:

  GRE offers near-perfect resistance to acidic wash water and high-chloride seawater.

• Lightweight：

  The density of GRE is only about 1/4 that of steel. When installing scrubbers in the ship's superstructure, weight reduction is crucial for maintaining ship stability and optimizing the center of gravity. Lightweight piping also reduces the load on support structures and simplifies installation.

• Low Maintenance Costs & Long Service Life：

  Due to its superior corrosion resistance, GRE piping requires almost no maintenance throughout its lifecycle (e.g., welding repairs, replacement of corroded sections), with a typical design service life of over 20 years.

• Excellent Hydraulic Characteristics：

  The inner wall of GRE piping is very smooth , resulting in low flow resistance and lower energy consumption for fluid transport. For systems requiring pumping of large volumes of wash water, this helps reduce operational energy use.

• Ease of Installation：

  Pipes are typically installed using socket-and-spigot bonding or flanged connections, allowing for rapid installation. There is no need for welding and subsequent weld corrosion protection as required for steel pipes.
