  SHS-self-propagating
ceramic composite steel pipe and fittings,
the new generation of wearable and corrosion resistant
engineering pipeline, belongs to "863" Hi-tech
Plan products. It is mainly used as grindable
granule and corrosives in electric power, metallurgy,
mining, coal, and chemical industry when transporting
sandstone, coal fines, clinker, and aluminum liquid,
etc. It is the ideal wearable and corrosion resistant
engineering pipeline, with wear resistance 15
times higher than common steel pipe, smooth inner
surface, and favorable liquor resistance.
The
composite pipe is composed of three layers: ceramic,
intermediate, and steel layers. The ceramic layer
is formed by molten alumina at a temperature above
2500℃. The molten alumina produced from the reaction
Fe2O3+2Al=2Fe+Al2O3 spreads on the inside wall
of the steel pipe under the influence of a centrifugal
force, then solidifies, so the ceramic layer has
high density and smooth surface and bonds to the
steel pipe. The
ceramic-lined steel pipes have numerous exceptional
properties including good resistance to abrasion,
heat, mechanical and thermal shocks. The pipes
are easy to weld and fixing. They are very suitable
for the transport of abrasive materials and thus
can replace cast ceramic pipes, alloy pipes, and
resin-lined steel pipes. They have a wide variety
of application in mining, power plants, water
conservation and metallurgical, coal, petroleum,
and building material industries.
Features:
High abrasion resistant:
Vickers hardness of the corundum lining is HV1100
to1500, as high as that of tungsten-cobalt hard
alloys, and the abrasion resistance is 20 times
as carbon steel pipes. Its rigidity is the highest
among all oxides.
Corrosion resistant:
Corundum is a neutral material, and is acid-proof
and fouling -free.
Heat resistant:
The pipe can work under circumstances of -50 to
800 degrees Celsius.
Convenient installation:
It is much lighter than any other types of composite
pipes, and can be welded or connected through
flanges.
Cost effective:
Ceramic-lined composite steel pipe can take the
place of expensive stainless steel, titanium,
nickel, cast stone or alloy pipes. Extended service
life can also reduce maintenance cost.
