Stellite Thermocouple Protection Tube
We produce the Thermocouple Protection Tube for many years which in made of high temperature Metal Ceramics and Stellite Alloy , The material was researched by professor Li Rongjiu in Northeastern University who has been engaged in this filed for more than 30 years , we bought his technology and produce it exclusive .
