The bimetal cylinder liner is one of the most widely used hydraulic end fittings of the mud pump at present. The bimetal cylinder liner combines the advantages of hot-forged high-wear jacket and high-chromium wear-resistant and corrosion-resistant inner liner. The outer liner is made of high-quality carbon steel by hot pressing once, and the inner liner is made of high-chromium cast iron by centrifugal casting. The tensile strength of PSI is higher than HRC62 after heat treatment, and it can withstand 7 000 psi mud pressure. Its inner surface is smooth as a mirror, and the dimension tolerance of inner hole is strict. Its normal service life can reach more than 800 hours.
