SHS (Self-propagating High-temperature Synthetic process) ceramic
lined steel pipe and elbow create a new generation of abrasion and
corrosion resistant engineering pipeline.
The Manufacturing Process of Pipe and Elbow:
SHS (Self-propagating High-temperature Synthetic process) ceramic
lined steel pipe and elbow create a new generation of abrasion and
corrosion resistant engineering pipeline.The composite steel pipe
is composed of three layers: ceramic, intermediate, and steel
layers. The ceramic layer is formed by molten alumina at a
temperature above ***0 degree. 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.
Abrasion Resistant Ceramic Lined Pipes have been uniformly produced
by a thermite reaction induced under the influence of a centrifugal
force (Centrifugal Thermite Process) without any high-temperature
furnace facilities. The characteristic feature of the present
process for forming uniform ceramic layers is in its reaction
propagation as well as the reaction heat and centrifugal force. It
is very important in improving the quality of the ceramic lined
pipes to find the proper conditions of the reactant and centrifugal
force; the former mainly determines the produced ceramic layer
quality and the latter the achievement of layer separation and the
mechanical properties of the pipes.
Ceramic lined tube has great resistance against corrosion, abrasion
and thermal shock. Features and Advantages:
1). High Abrasion Resistant: Vickers
hardness of the corundum lining is HV***0 to***0, as high as that
of tungsten-cobalt hard alloys, and the abrasion resistance is *0
times as carbon steel pipes. The composite ceramic lined steel
elbow was used in a mining plant for about fifty thousands hours.
The general service life of common steel elbow is about **0
hours.
2). Corrosion Resistant: Corundum
is a neutral material, and is acid-proof and fouling
-free.
3). Heat Resistant: Ceramic
lined composite steel pipe can work under circumstances of **0 to
**0 Celsius degree .
4). Lower Weight and Convenient Installation: The
ceramic lined steel pipes are lighter than alloy pipes, cast iron
pipes, and cast stone pipes and can be welded or connected through
flanges, which reduces the expense of transportation and makes the
pipes easier to install. For the pipes with the same sizes, types
and length, the weight of ceramic pipe is about 1/2 of the wearable
cast alloy steel pipe\'s, while the cost has reduced *0%~*0% per
meter. The weight of ceramic lined steel pipe is about 1/3 of the
cast stone bent pipe\'s, 1/2 of the cast stone straight
pipe\'s.
5). Lower Cost: Ceramic
lined pipes can take place of expensive stainless steel, titanium,
nickel, cast stone or alloy pipes. Extended service life can also
reduce maintenance cost.
