IntroductionCeramic alumina insulator is used in thermocouple assembly which applied for high temperature messuring.Al2O3 content determines the measuring temperature level, Al2O3 content higher, the temperature is higher.Alumina Tubes is the the workhorse of the advanced technical ceramic tubes. It has good mechanical and electrical properties, wear resistance and corrosion resistance. It has relatively poor thermal shock resistance.2.Technical Date3.Advantages1) A variety of specifications available.2) Satisfy various technical request3) Lower medium spoilage4) Good insulation performance and high temperature resistance5) High pressure6) Mechanical strength7) Wear resistance4.Standard SizesHigh Alumina InsulatorDimensionOuter dia. mmInner dia.mmLength mmIf you need others,wecan customize for you.ItemInsulated tubeSingle hole2-1201-11010-2000(inner core)Double holes1-100.4-210-2000Four holes2-100.5-210-20006.
