Anti-corrosion Alumina Ceramic Bend/elbow For Coal Powder Transportation System

Product Detail

Abrasion resistant ceramic linings mainly include elbows, straight pipes, tees, reducer pipes, etc, and they are used for ceramic lined pipework and fittings of pneumatic conveying and slurry pumping. The conveying medium is featured by high hardness, fast and big flow, alumina ceramic rings can effectively reduce the speed of wearing through by continuous impact, abrasion and corrosion to pipe wall when long-term conveying medium.

 

Wear is fast when the piping conveying pointed materials(ash, coal powder, mine flavor powder, tailings, cement etc), especially for elbow. Pipeline corroded will be quickly worn out when conveying gas, fluid and solid materials of intensive corrosion.

 

It can be divided in to the following:

Product          Technical Parameter	92	95
Al2O3%	=92	=95
Fe2O3%	=0.2	=0.15
Mohs' hardness	8	9
Water Absorption (%)	=0.02
Bulk Density(g/cm3)	=3.60	=3.65
Abrasion(%)	=0.02

  

Application:

Wear-resistant alumina pipe is widely used in pneumatic conveying and hydraulic conveying for coal fired power plant, steel plant, chemical plant, metallurgy, cement, coal washeries, coal mining and other industries.

·In coal fire power stations, wear-proof aluminum oxide ceramic tubes are widely applied in conveying system of bottom ash to protect against wear.

·In hard coal mining industry, wear-resisting alumina pipes are used to protect pipelines against abrasion of coal dust and tailings for backfilling.

·In coal washery plant, the conveying pipelines of heavy media with solids are protected by wear resistant alumina linings.

·In chemical industry, corrosion resisting ceramic tubes have extremely effective on conveying system against caustic solutions with solid.

·In all kinds of different cyclones, including heavy medium cyclone, hydrocyclone
