Products Description
Titanium has good corrosion resistance, especially Ti-0.2Pd titanium alloy, so GR7 titanium alloy is widely used as sealing material for container equipment. gr7 titanium alloy has excellent corrosion resistance, and its corrosion resistance in reducing acid Compared with pure titanium, its performance is significantly improved, and it is more resistant to crevice corrosion than pure titanium. However, titanium-palladium alloys contain metal palladium, which has a high cost, which limits its further application. Gr7 titanium pipe is widely used in chemical plant due to its excellent corrosion resistance.
It is an alloyed titanium, with standard oxygen content and addition of palladium, has excellent corrosion resistance, so it is widely used for condenser, heat exachanger, and water treatment , desalination, evaporator and pipelines, also used in bicycle frames and other parts.
Alloy Gr7 titanium actually means add little palladium in pure titanium, it is the most corrosion resistant of all currently available titanium alloys, this grade is especially well suited to applications requiring resistance to general as well as localized crevice corrosion in a wide range of reducing acid environments, including chlorides, and where low pH and high temperatures above 180ºF (83ºC) to 500ºF (260ºC) are prevalent. It also exhibits good strength, welding and forming characteristics.

Specification:
It include Ti-0.2Pd, Ti-0.15Pd and Ti-0.13Pd, among which Ti-0.2Pd titanium pipe is more widely used in reactors, towers, autoclaves, heat exchangers, Pumps, valves, centrifuges, separators, pipes, fittings, electrolyzers. Gr7 is a titanium-palladium alloy. The metal "palladium" is added to the smelting of sponge titanium to form a grade7 titanium alloy ingot through vacuum melting. The material has corrosion resistance and is mostly used in the chemical industry. it inspection terms including water pressure test, ultrasonic test, eddy current test, flaring and flattening test.
