The bimetallic cylinder liner has the following performance advantages: 1. Combining the advantages of two metals: the outer shell is made of carbon steel hot pressed in one go, which has high tensile strength; The inner sleeve is made of high chromium cast iron by centrifugal casting, and after heat treatment, its hardness can reach HRC62 or above, and it can withstand mud pressure of 7000 psi. For example, it combines the advantages of forged wear-resistant outer sleeve and high chromium wear-resistant and corrosion-resistant inner sleeve, and has the characteristics of wear resistance, corrosion resistance, high pressure resistance, high temperature resistance, high strength, and high hardness. 2. Good surface quality: The inner surface is as smooth as a mirror, with strict tolerance for the inner hole size, and the inner surface roughness can reach within the range of 0.20. 3. Long service life: The normal service life can reach over 800 hours. 4. Reduce overall costs: It can lower transportation, maintenance, labor, storage, and other costs associated with drilling operations. 5. More resilient: Compared to alumina ceramic, composite ceramic cylinder liners, toughened composite ceramic cylinder liners, etc., bimetallic cylinder liners are more resilient and can reduce the wear of pistons and other accessories. Bimetallic cylinder liner is one of the widely used and widely used hydraulic end fittings for mud pumps, suitable for various working conditions. However, its specific performance is also affected by actual working conditions, maintenance and other factors.
