We provide ceramic cylinder liners for various domestic and foreign oil drilling mud pump models, suitable for drilling and production environments with deep oil reservoirs and harsh geological structures, as well as offshore oil and natural gas development.
Liner is divided into Ceramic Sleeve Liner, Double Metal Liner, Carburization & quenching Liner and Chrome-plated Liner. Ceramic Sleeve Liner, Material of sleeve is Zirconia and its shell is 45#(ASTM1045)forged steel.
Double Metal Liner
Material for shell is forged steel pipe or seamless steel tube, 45#(ASTM1045). Normalizing hardness degree is 160BHN(HB180-200), percentage elongation 17%(δ>17%),tensile strength not less than 85000PSI(σb>610Mpa), Flexural Strength not less than 60000PSI(σb>450MPa)and shell with HP.
Sleeve material is high chrome centrifugal, which is chrome containing 26-28%, its thickness 0.25~0.35 inch (6.35 -8.89mm. its standard thickness is 7mm and special thickness reduced has 3 kinds, 4mm, 4.5mm & 5mm. Normally, it means standard thickness if there is no special explanation ), quenching hardness HRC59-67.
Technical Parameters of Zirconia Liner is as following:
