Titanium U-Bent Pipe

Designed for high-performance heat transfer, our Titanium U-Bent Pipes are manufactured via cold working to ensure precise bend radii and uniform wall thickness. Available in Grades 1, 2, 5, 7, 9, and 23, these pipes resist saltwater, acids, and extreme temperatures, making them perfect for heat exchangers, boilers, and offshore applications. With seamless and welded options, our U-bends meet ASTM B338, ASME SB338, and DIN 17861 standards. Customizable in diameter (6.35–76.2mm), wall thickness (0.3–10mm), and bend radius, these pipes undergo 100% hydrostatic testing for leak-proof reliability. Ideal for chemical, power, and marine industries, they reduce maintenance costs while enhancing durability.

Why Choose Titanium U-Bent Pipes?

Corrosion Resistance – Withstands seawater, chlorine, and sulfuric acid (Grades 7 & 12 excel in aggressive environments).
High Strength-to-Weight Ratio – 40% lighter than steel with comparable strength (Grade 5 for aerospace applications).
Thermal Efficiency – Optimized for heat exchangers and condensers, improving energy transfer by 15–20%.
Biocompatibility – Grade 23 (Ti-6Al-4V ELI) is ideal for medical and pharmaceutical uses.
Customizable – Tailored bend radii, lengths (up to 18m), and surface finishes (polished, pickled, or passivated).
