From the Perspective of Marine Piping Systems

 
Copper fittings serve as the lifeline of navigation safety for ship seawater, cooling, fuel, and ballast systems, which operate under long-term harsh conditions: high salt spray, severe corrosion, strong vibration, and high pressure. The quality of copper fittings directly determines no leakage, no corrosion, and no fracture.
 

1. Core Importance

 
  1. Excellent seawater corrosion resistance
     
    Brass, tin bronze, and cupronickel (C70600 / C71500) have natural resistance to chloride ions, seawater erosion, and marine biofouling, making them irreplaceable key connectors in marine piping.
  2. System sealing and anti-vibration performance
     
    Continuous vibration from main engines and waves can cause failures, leaks, shutdowns, or even accidents. The strength, toughness, and sealing performance of copper fittings form the basis of system reliability.
  3. Long service life and low maintenance cost
     
    Marine copper fittings have a service life of up to 15–20 years, greatly reducing docking and replacement costs and improving vessel availability.
 

2. Optimum Processing Technology for Piping Systems

 
  • Blank forming: Precision forging
     
    Refines grains, improves density and strength, and provides far better fatigue resistance than castings, preventing vibration-induced cracks.
  • Heat treatment: Solution treatment (950–980°C water quenching)
     
    Eliminates internal stress, enhances corrosion resistance, and prevents stress corrosion cracking (SCC), which is essential for seawater piping.
  • Machining: CNC precision finishing
     
    Ensures dimensional tolerance ≤ ±0.05 mm and surface roughness Ra ≤ 1.6 μm for threads and sealing surfaces, guaranteeing reliable high-pressure sealing.
  • Welding: High-purity argon arc welding (GTAW)
     
    Produces oxide-free, porosity-free welds with strength and corrosion resistance close to the base metal, complying with classification society pressure requirements.
  • Surface treatment: Pickling and passivation
     
    Forms a dense protective film to further improve corrosion resistance in seawater environments.
