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-315、 Sicer-317、Sicer-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.

(1) The specific ceramic sleeve is selected according to the slurry pump and the drilling condition. Its coat is made of high quality forging carbon steel, and the tolerance is strictly controlled, so as to ensure the flexible and convenient site installation.

(2) With the unique microstructure and high- precision grinding and polishing process, our high-tech ceramics ensure a fine and smooth working surface. From the conformity testing of piston and ceramic working surface on friction and wear, result shows that the service life of piston increases to more than 300 hours.

(3) The low- stress assembly technology and standard production of specific ceramic/metal ensures the stability and reliability in quality.

(4) Tens of thousands of ceramic sleeve products have been successfully applied in various oil well at home and broad.
