Great Hardness—Rockwell hardness is 88 which is far exceeding wear-resistant steel and stainless steel.
Good Abrasion Resistance—its abrasion resistance is 266 times that of manganese steel and 171.15 times that of high chromium iron.
The service life of pipes can be sxtended over 10times under the same working condition.
Corrosion Resistance—High alumina ceramics has stable molecular structure that can resist corrosion from various acid and alkali media.
Light Weight—its density is 3.6g/cm3 which is only half that of steel, highly lowering the dead weight of the pipe.
