Refractory Tubes
Refractory fiber and cement laminate tubes have a maximum
service temperature of 1500°F (815°C). The tips of the tubes
are made from silicon carbide to increase the response time.
Refractory tubes are used in molten Zinc and Aluminum die
casting applications. These refractory tubes will not shatter
like ceramic tubes. They also will not contaminate the molten
metal as a stainless steel or iron protection tube.

Refractory Cement
Refractory coating and bonding cement is available to provide an abrasive and shock resistant surface on refractory fibers, brick and other
insulations. It is flame and heat resistant. It may be used also as a corrosion barrier for cast iron protection tubes, metal transfer troughs and
other surfaces that come in contact with molten aluminum and zinc. It may be brushed or sprayed on. Available in pint, quart, gallon and 5
gallon pail sizes. Consult factory for availability and pricing.

Slip Cast Alumina Silica
Refractory Tubes
Slip Cast alumina silica refractory tubes have
a maximum service temperature of 1500°F (815°C).
These tubes are constructed by casting the refractory
material around an 1/2” steel or 304 stainless steel
protection tube. Alumina silica refractory tubes are
used in molten Zinc and Aluminum die casting
applications. Alumina silica tubes have excellent
thermal shock and mechanical damage resistance
They are non-wetting and will not contaminate the
molten metal as a stainless steel or iron protection
tube.
