SSiC Cold Air Pipe


Silicon carbide cooling air pipe AKA cold air intake pipe is mainly used to cool or reduce the temperature of roller kiln or tunnel kiln, such as home porcelain, sanitary porcelain, building porcelain, etc. It boasts an excellent performance of high-temperature resistance and thermal shock resistance. It is air-cooled from 1000 ℃ to room temperature without crack for more than 50 times

Oustek’s silicon carbide cold air intake pipe adapts isostatic pressing, net size sintering and mechanical finishing technique, it produces tubes with density up to 3.1kg/m³. Adopts silicon carbide for high-quality refractories with purity up to 98.5%, so the maximum working temperature reaches up to 1380 ℃ (2500 ℉).


For the cooling area of tunnel kiln, shuttle kiln, roller kiln and other industrial kilns in sanitary ware, high-pressure electromagnetic, honeycomb ceramics, Class-A light foamed ceramics, microcrystalline stone industry, etc.


  • High strength, high hardness, wear resistance, low density.
  • High attenuation performance, low thermal expansion, high thermal shock resistance, high temperature creep resistance.
  • Chemical stability, corrosion resistance, especially hydrofluoric acid resistance.
  • High-temperature resistance, excellent refractory material.
  • Long service life and reduce overall investment cost


Isostatic Pressing

With self-own isostatic pressing equipment, all products use isostatic pressing technology to make the green body uniformly stressed, the density distribution is uniform, and the product performance is greatly improved. There are incomparable advantages when molding complex shapes, elongated products, large-sized products, and precision-sized products.
