FIELD: physics.
SUBSTANCE: temperature measuring pipe is composite and has a rigid bar (1) which is cooled for protection from corrosion and melting, and a nozzle (15) on which there is a thermocouple (9) lying at the end of the pipe and made from corrosion resistant noble metal with high melting point. Between two metals of the bar and nozzle there is an aluminium oxide layer in order to prevent electrochemical interaction between them which causes corrosion.
EFFECT: design of a pipe for measuring temperature which is capable of withstanding high temperature and corrosion.
