1. Monometallic Liner
The monometallic liner undergoes carburizing and high-frequency treatment, achieving a hardness of HRC 58-62. It features high surface finish, wear resistance, corrosion resistance, and extended service life, making it suitable for use in moderately corrosive mud environments.
2. Bimetallic Liner
The bimetallic liner is one of the most widely used and highest-volume consumables in the hydraulic end of mud pumps. It combines the advantages of a hot-forged high-wear outer sleeve and a high-chromium wear/corrosion-resistant inner sleeve. The outer sleeve is formed via hot pressing using high-quality carbon steel, while the inner sleeve is centrifugally cast from high-chromium cast iron. The outer sleeve exhibits tensile strength exceeding 900,000 psi, and the heat-treated inner sleeve achieves a hardness above HRC 62. Capable of withstanding mud pressures up to 7,000 psi, its mirror-smooth internal surface and strict dimensional tolerances deliver a typical service life exceeding 800 hours.
3. Ceramic Liner
As global oil and gas exploration expands into increasingly harsh environments, conventional metal liners struggle to meet the demands of high pressure and extreme wear despite frequent replacement. Ceramic liners utilize three material systems: zirconia ZrO, zirconia-toughened alumi
na (ZTA), and high-performance A-99 alumina ceramic. Manufactured from high-purity nano zirconia and alumina powders, they undergo single-pass cold pressing, high-temperature sintering, assembly, and precision grinding and polishing. These liners exhibit exceptional flexural/tensile strength, high fracture toughness, and superior resistance to acid/alkali corrosion.
4. Nickel-Based Alloy Liner
Advancements in material science have led to the development of nickel-based alloy liners. Using vacuum sintering technology, a 1.5mm-thick alloy layer is bonded to the liner's inner wall. The sintered layer incorporates high-performance rare-earth nickel-based alloy powder blended with micron-scale hard alloy particles, ensuring uniform dispersion of wear-resistant hard phases. This microstructure prevents delamination while enhancing overall abrasion resistance. The well-alloyed sintered layer achieves strong bonding and a Rockwell hardness of HRC 60-64.
