Based on the problem of abrasion, corrosion and brittleness rupture of flange at the wield bottom part occurred for thermocouple protection jacket in petrochemical field at home and abroad, a fissional thermocouple is developed. The developed disassembly thermocouple, which adopts the novel alloy material, the integration forging modeling and deep blind drill technology, can replace the traditional wielding technique. It solves the protection jacket and flange material problem rationally. It not only sharply increases the thermocouple jacket abrasion and corrosion resistance performance, but also save the flange material efficiently, and is a novel energy saving thermocouple.
