Stainless Steel High Pressure Pipe 316Ti 6" SCH80, ASME SA-312, Chloride Resistance, Offshore Rigs
316Ti Stainless Steel High-Pressure Pipes (6" Sch80) by Jiangsu China Steel Union Industrial Co., Ltd are engineered for extreme offshore and subsea applications requiring robust chloride resistance and high-pressure integrity. Compliant with ASME SA-312, these titanium-stabilized (Ti: 5xC) austenitic stainless steel pipes withstand pressures up to 1,500 psi and resist pitting, crevice corrosion, and stress corrosion cracking (SCC) in seawater, H₂S, and chloride-rich environments. The 6" Sch80 dimensions (OD: 168.3mm, Wall Thickness: 10.97mm) ensure durability in deepwater drilling risers, hydraulic control lines, and injection systems. Seamless construction and rigorous testing guarantee reliability in offshore oil rigs, FPSO vessels, and subsea production systems.
