Oil Drilling Mud Pump Bi-metal Liner
The bi-metal cylinder liner is the most widely used and of the largest amount at fluid end of mud pumps. Bi-metal cylinder liner is composed with
a highly worn forged external liner which is made in high quality carbon steel through one-step hot press molding process, and a ware/corrosion-resisting high chromium-nickel internal liner which is made in high chromium cast iron through centrifugal casting process. The tension
strength of external liner is over 900000psi, while the hardness after heat treatment of internal liner is no less than HRC62 which can bear mud
pressure at 7000psi. The internal liner is with smooth surface with the inner-hole dimension tolerance strictly controlled, and its normal using life is over 800 hours.
External liner: is forged in #45 steel, with tension strength σb>610MPa, yield strength σs>450MPa, percentage elongation §>17%, and hardness
HB180-200.
Internal liner is made in high chromium cast iron through centrifugal casting process, with the annealing hardness HRC≤40m, and quenching hardness HRC60-67.
