Application:  Tantalum thermowells are often used to protect thermocouples when monitoring the temperature of highly corrosive chemical solutions and agents. Solid machined and drilled tantalum thermowells are good for these applications. But to save money, a thin (0.013 - 0.015 inch thick) tantalum sleeve is often used. This is fitted over a thermowell made of type 316 stainless steel.

Tantalum sleeve fitted over a stainless steel thermowell provides an economical way to protect against corrosion.

e.g. tantalum electrode is consisted of seamless tantalum tube and the copper rod (straight rod), the copper rod is usually placed inside tantalum tube, tantalum tube is used as tantalum sleeve or tantalum protecting sleeve against vitriol, sulfide solution, natrium solution and manganic solution, hydrochloric acid solution and phosphate solution, acetic acid, formic acid, formate and hot alkali solution.
