Tinned Copper Round Pipe 1/4"-3", Marine Grade Protection,
Saltwater Corrosion Resistant
tinned copper round pipes are engineered for marine and coastal environments requiring
unmatched resistance to saltwater corrosion. With diameters ranging
from 1/4" (6.35mm) to 3" (76.2mm), these pipes feature a uniform tin coating that protects against
pitting, oxidation, and galvanic degradation. Compliant with
marine-grade standards, they are ideal for shipbuilding, offshore
platforms, and desalination plants, offering longevity in harsh
saline conditions while retaining copper’s inherent thermal and
electrical conductivity.

3. Import Advantages
① Marine-Grade Durability
Hot-dip tinning process prevents saltwater-induced corrosion,
extending service life by 3–5x compared to bare copper.
② Rigorous Quality Control
Each batch undergoes salt spray testing (ASTM B117) to ensure
1,000+ hours of corrosion resistance.
③ Customization Options
Pre-cut lengths, flared ends, or pre-insulated variants with PVC
jackets for subsea applications.
④ Fast Global Shipping
Pre-stocked sizes and partnerships with marine logistics providers
ensure timely delivery to ports worldwide.
⑤ Cost Savings
Reduced maintenance and replacement costs due to superior corrosion
protection in aggressive environments.
4. Key Applications
- Marine Cooling Systems: Seawater intake/discharge lines for ship engines and heat
exchangers.
- Offshore Oil & Gas: Corrosion-resistant piping for platform firewater systems and
hydraulic circuits.
- Desalination Plants: Brine and freshwater transfer lines resistant to chlorides and
sulfides.
- Coastal Infrastructure: HVAC condensate drains, water supply networks in high-humidity
regions.
- Aquaculture: Saltwater-resistant tubing for fish farming pumps and oxygenation
systems.
