As the increasingly harsh condition in the exploration of oil and gas, numerous of metal sleeves have been consumed and replaced due to high pressure and severe abrasion. As a result, it cannot provide the drilling machine a consecutive running; SICER-ceramic sleeves that made of unique Zirconia(Sicer-315ã Sicer-317ãSicer-319), Sub-A99(Sicer-312), going through the strict procedures of fine powder processing, cold isotastic press, high temperature sintering , accurate assembling and precise grinding and polishing, shows superior performance in bending strength, fracture toughness, abrasion resistance. Compared to the traditional metal sleeves, the service life of SICER-ceramic sleeves has increased more than 10 times. Consequently, there would be less shutdown time and the lower running expenses. Each pump will achieve higher output and benefit.
