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.

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.
