Types of wear-resistant ceramic pipe and its application in industrial production
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 .
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.
