Nozzles Pipe Application: Industrial

Nozzles Pipe

BMW's nozzles pipe are sintered alumina tube with excellent temperature stability. They are popularly used as furnace tubes and protecting and insulating tubes for high temperature thermocouple assemblies. Because of their high purity and fine grain structure, BMW 's nozzle pipes possess high wear resistance high strength, high thermal conductivity and insulating properties.

The Al2O3 content of BMW 's nozzle pipes is more that 99% making it perfectly suitable for use in Platinum/Platinum-Rhodium thermocouple as any presence of silicate would contaminate these thermocouples and reduce their service life.

BMW's nozzle pipes tubes are available in a variety of sizes with one end closed as protection tubes or both ends open with 2-hole or 4-holes as insulating tubes.

PROPERTIES

Temperature stability up to 1800°C BMW's nozzles pipe tube exhibit stability at temperature as high as 1,800°C giving it advantage over metal or glass material. Application temperature also is influenced by the tube geometry, the diameter, the wall thickness and the method of installation i.e., horizontal or vertical.

High chemical resistance BMW's nozzle pipes has excellent chemical resistivity and are corrosion resistant against most acids and alkaline. Also, the stability in neututral or reducing atmosphere is excellent.

High electrical insulation. Due to its very high electrical insulation properties, BMW's nozzle pipes is ideal as thermocouple wire insulating tubes and thermocouple protection tubes even in electrically heated furnaces.

Mechanical wear resistance Due to high mechanical wear resistance BMW's nozzle pipes tubes exhibits long term stability even when subjected to abrasive environment.

Dimensional flexibility. Various standard sizes are available from 0.5 mm through 300 mm in diameter. Tubes with non-standard sizes can be offered in accordance with customer’s specifications and dimensions
