Including abrasion resistant ceramic pipe elbow, straight pipe , structural tee, head size, radius sections , adjustable pipe , mainly used for the air force , pumping slurry pipeline and other materials . Because the transmission medium with high hardness, flow speed , flow characteristics, can effectively reduce the transmission medium to the wall to produce long-lasting impact, abrasion , corrosion fatigue causes the pipe was gradually worn out speed.

1 , the definition of wear-resistant ceramic pipe
Depending on the working conditions of wear on the wear-resistant ceramic pipe lining materials have different choices. Resistant ceramic lined pipe ( lining of aluminum oxide , silicon carbide , zirconia, silicon nitride , sialon , aluminum nitride, boron nitride , etc. ) ; resistant alloy tube ; hexsteel wearable pipe fittings ; rubber resistant steel grinding tube ; wear-resistant plastic tube ; wear-resistant cast stone pipe ; wearable self-propagating composite pipe ; rare earth alloy wear-resistant pipe.

2 , the main application of wear-resistant ceramic pipe
In addition to used in coal-fired power plants wear elbow ash , slag pipe , powder , powder tube back , desulfurization pipes , but also widely used in the following industries:
Mining : Coal industry CWS , washing mud , mine backfill , mine coal powder ;
Metal mines : concentrate and tailings transport wear elbow ;
Metallurgy : Steel mill blast of pulverized coal injection , slag and other transmission pipelines ; CAO, zinc Bei sands pipeline , transporting steel alloys, refining , etc. Preferably wear elbow ;
Cement : raw slurry wet rotary kiln production line conveyor , coal transportation, upgrading cutting machine , pneumatic conveying finished unloading cement , concrete wear elbow .
Chemical : pulverized coal pipeline , transporting raw materials such as silica fume wear elbow .

The main application sectors 3 , wear-resistant ceramic pipe
In addition to used in coal-fired power plants wear elbow ash , slag pipe , powder , powder tube back , desulfurization pipes , but also widely used in the following industries:
Mining : Coal industry CWS , washing mud , mine backfill , mine coal powder ;
Metal mines : concentrate and tailings transport wear elbow ;
Metallurgy : Steel mill blast of pulverized coal injection , slag and other transmission pipelines ; CAO, zinc Bei sands pipeline , transporting steel alloys, refining , etc. Preferably wear elbow ;
Cement : raw slurry wet rotary kiln production line conveyor , coal transportation, upgrading cutting machine , pneumatic conveying finished unloading cement , concrete wear elbow .
Chemical : pulverized coal pipeline , transporting raw materials such as silica fume wear elbow .

4, the detailed use of wear-resistant ceramic pipe
Transport has been around electricity, metallurgy, coal , petroleum, chemicals, building materials , machinery and other industries, and high-speed developing. When the wear-resistant ceramic grinding large pipeline materials (such as ash , coal , ore concentrates , tailings, cement, etc. ) , there is an abrasion resistant ceramic pipe faster , especially wear elbow faster. When the pipeline in the wear-resistant ceramic having a strong corrosive gas , liquid or solid , there is a problem of corrosion and wear-resistant ceramic pipe is quickly destroyed . When the pipeline resistant ceramic materials with higher temperatures , there is a heat-resistant steel prices are very expensive problem. After resistant ceramic pipe market, these problems are solved. Wear resistant ceramic pipe is widely used in mine backfill serious , transporting ore concentrate and tailings , coal-fired power plant feed powder , slag , ash and other wear-resistant ceramic pipes are also very suitable . Resistant ceramic pipes are transported strong corrosive acid, alkali , salt and abrasive both solid , wear-resistant ceramic pipe ideal liquid delivery . In the high-temperature corrosion resistant ceramic pipe , high temperature or high-temperature ablation wear occasions using very safe and reliable.

5 , wear-resistant ceramic pipe production technology
Resistant ceramic pipes are using self- propagating high temperature synthesis - centrifugation manufacture. After that is placed inside the centrifuge tube seamless steel mold , joined in the steel and aluminum oxide powder mixture , the mixture called thermite in chemistry , centrifuge tube mold rotation reaches a certain speed , through a Mars ignite thermite , thermite now own , the combustion wave spread rapidly , following violent chemical reaction occurs when the spread.

Chapter One – What are Alumina Ceramics?

Alumina Ceramic Liner is an industrial ceramic that has high hardness, is long wearing, and can only be formed by diamond grinding. It is manufactured from bauxite and can be shaped using injection molding, die pressing, isostatic pressing, slip casting, and extrusion.
