Elvis Nickel Alloys stands out as a leading manufacturer and supplier of Titanium Grade 7 Pipes right here in Houston, USA. Our pipes are designed to resist corrosion, making them perfect for tough and aggressive environments. Titanium Gr 7 (UNS R52400) is a commercially pure titanium alloy, enhanced with a touch of palladium (0.12–0.25%), which boosts its ability to withstand crevice corrosion and harsh reducing acids. Adhering to ASTM B338/B861 standards, our Titanium Gr 7 pipes find their place in chemical processing, nuclear power, and marine systems. At Elvis Nickel Alloys, we pride ourselves on delivering precision-engineered piping that you can rely on, even in the most extreme and corrosive conditions.
Titanium Grade 7 Pipes are primarily made of titanium (≥99.1%), with a crucial addition of palladium (0.12–0.25%) that improves their resistance to reducing acid environments, such as hydrochloric and sulfuric acid. These pipes boast a tensile strength of about 345 MPa and a yield strength of around 275 MPa, along with excellent ductility and weldability. Titanium Gr 7 maintains its mechanical stability across a wide temperature range and excels in chloride-rich, acidic, and moist settings. Its corrosion resistance is on par with Grade 2 but shines in crevice and reducing conditions, making it the go-to choice for demanding chemical applications.
