High temperature Thermocouple Protection Tubes up to 1,650 ° C in open air.

We have developed a new range of high temperature thermocouple protection tubes sheaths with an outstanding performance for temperature control in (non)-ferous foundries and smelters and are extremely cost effective compared to other materials, such as cast iron, silicon carbide and alumina. This new quality offers a clear price advantage against HEXOLOY SE material with equal or superior performance.

We have three standard diameters high temperature thermocouple protection tubes in stock in lengths varying from 150 mm up to 2,000 mm. Tooling cost may apply. Stock items have a standard groove. Maximum temperature in a controlled atmosphere is up to 1,850 degrees Celsius. Maximum application temperature in open air up to 1,650 degrees Celsius.

Sialons are alloys of silicon nitride and possess a unique combination of physical properties, such as high strength, toughness, excellent thermal shock resistance and resistance to corrosion. Some examples are usage in a highly corrosive environment in the electrolysis or potroom at 900 degrees Celsius. Our high temperature thermocouple tubes are also used in brass, copper, cast iron, stainless steel and even silicon metal.

Gas-tight stainless steel adapters are specially suitable for the thermocouple protection tubes sheaths. Test our new valve adapter for low-pressure die casting machines.
