Large diameter ceramic lined pipe is the use of SHS high
temperature synthesis technology, that is, “SHS” technology
composite, is a national High-tech “863” project, is the original
national metallurgical Industry Department, the Ministry of
Electricity Project focused on the promotion of new products, the
tube from within to outside by ceramic (corundum) layer, transition
layer and steel layer composed of three parts.
Large diameter ceramic lined pipe, is a high-tech production
technology-self-fuel high temperature clutch synthesis method. The
tube is composed of corundum ceramics, transition layer and steel
three layers respectively from inside to outside, the ceramic layer
is formed dense corundum porcelain (Al2O3) at high temperature
above 2,200 ℃, and the steel pipe is formed firmly by the
transition layer.
Because of its high strength, good toughness, impact resistance,
good welding performance and high hardness, high abrasion
resistance, corrosion resistance and heat resistance, the composite
pipe overcomes the characteristics of low hardness, poor abrasion
resistance and poor toughness of ceramic steel pipe. Therefore, the
composite pipe has good wear-resistant, heat-resistant, corrosion
resistance and mechanical impact and thermal shock, good
weldability and other comprehensive performance. Is the
transportation of granular materials, grinding, corrosive media,
such as the ideal wear-resistant, corrosion resistance pipeline.
Because the tube has wear resistance, corrosion resistance, heat
resistance, it can be widely used in electric power, metallurgy,
mining, coal, chemical industry and other industries as conveying
sand, stone, pulverized coal, ash slag, aluminum liquid, such as
grinding granular materials and corrosive media, is an ideal
corrosion-resistant pipeline.
I. Application in metallurgy and electric power industry
Metallurgy, power industry transportation of pulverized coal, ash,
mud, limestone paste slurry, such as the annual need to consume a
large number of metal pipelines. The use of ceramic composite pipe
to replace other pipelines, with high wear-resistant, long life,
easy installation and remarkable economic benefits. Shandong
Liaocheng Chang-run thermal power plant, Liaocheng China power
Plant, Beijing North New building materials group, Henan Hebi Power
Plant, Gansu Pingliang Power Plant, Taiyuan Coal preparation plant,
Shimen power plant in Hunan, Hebei Jinniu Energy Co., Ltd. Gequan
Coal Preparation plant, Xingtai coal preparation plant and other
industrial operations, its operating life is more than 10 times
times or even dozens of times times more than steel pipe.
II. application in mining and coal industry
(1) Mine: mine filling, concentrate powder and tailings
transportation to the pipeline of serious wear, the past use of
mineral powder conveying pipelines such as Panzhihua, Daye mine,
such as the service life of less than one year, the tube can
increase the life expectancy by about 5 times times.
(2) Coal: Coal preparation and long-distance pipeline
transportation of coal is commonly used in wet transport, the
requirements of the pipe is both wear-resistant and
corrosion-resistant, the use of the tube can be used as a long life
transport pipe, the economic benefits are considerable.
Iii. Other
(1) The tube does not pollute and does not adhere to the molten
aluminum solution. It is an ideal material to manufacture molten
aluminum equipment, aluminum liquid conveying pipe and liter liquid
pipe which are sensitive to iron pollution and need heavy labor for
finishing and maintenance after use.
(2) The tube has good abrasion resistance and heat-resisting
corrosion. It is suitable for conveying corrosive materials
containing solid particles and high temperature corrosive gas and
sulfur-containing hot water.
