Titanium Alloy Pipe (Ti-6Al-4V, Grade 5, Grade 2, etc.)
Engineered for industries demanding lightweight durability, extreme corrosion resistance, and high-pressure performance, titanium alloy pipes are seamless or welded solutions optimized for aerospace, medical, marine, and chemical applications. Composed of Ti-6Al-4V (Grade 5: Ti-90%, Al-6%, V-4%), these pipes deliver 1,000 MPa tensile strength at 40% lighter weight than steel, while resisting seawater corrosion, chlorine, and acidic environments. Certified to ASTM B861, AMS 4943, and ISO 5832-3, they outperform stainless steel and aluminum with 10x lifespan in aggressive conditions.
