Titanium alloy pipes are not resistant to corrosion in certain materials
Nov 12, 2018

Titanium alloy tube is not corrosion resistant to certain substances, such as high temperature (about 650 ℃ or above) with other reactive gas, air temperature above 400 ℃ oxygen halide salts; Reducible inorganic acids and acidic salt solutions, including oxalic acid, hot concentrated formic acid and trichloroacetic acid; Various acid solutions with fluorine concentration higher than 100ppM; Hot concentrated alkali solution; Dried halogen gas (may cause combustion in dry chlorine gas and bromine gas); Some strong oxidizer, the same oxygen and anhydrous fuming nitric acid peroxide, oxygen content more than 40% (volume) of the mixed gas and molten metal temperature over 450 ℃.

It should be noted that the titanium alloy tube absorbs hydrogen generated by the corrosion reaction under the reducing conditions in some high-temperature gases, and can also absorb hydrogen generated by dry cathode discharge. Although the weight loss of titanium is small in some cases, the damage in other aspects is not obvious, only the package will slowly accumulate, and finally the titanium becomes brittle and cannot be used.
