1.Premium Chromium Liners(Bi metal liner,Hy-chorme liner )combine the strength of a forged steel out shell with the abrasion and corrosion resistance of a high chromium iron inner sleeve. These liners feature a centrifugally cast high chrome iron sleeve which is machined and heat treated to a minimum uniform bore hardness of 62RC. Each liner is machined to close tolerance to assure ease of installation and long liner life with the inside diameter of these premium liners honed to a mirror-like finish for smooth even wear during the life superior performance under tough corrosive and abrasive conditions.
Outer Shell: 45# forged steel, tensile strength is Ãb 610MPa, yield strength is Ãs450MPa, elongation is ´17%, hardness is HRC180-200 Inner Sleeve: Hy-chrome forged steel (centrifugal forged). Annealing hardness is HRCd40. Quenching hardness is HRC59-67.

2.Ceramic liners combine the strength of a forged steel out shell with the abrasion and corrosion resistance of a ceramic inner sleeve. We provide Zirconia(ZrO3) sleeves as well as Alumina(AL2O3) sleeves of which Zirconia exhibits better impact strength, higher hardness and can be honed to finer surface finishes than alumina.
3.Chromium-plated Liners: We offer chromium-plated liners made from premium forged steel with the core plated by chrome. The chrome-plated liners have hardening characteristics of 58 to 62 Rockwell C hardness. Material is 45# forged steel, tensile strength is larger than 450MPA, elongation is larger than 17%, hardness is HRC180-200. The bore is plated by chrome, thickness is 0.15-0.18mm, hardness is HRC 58-60.
4. Hardened liners offer economy in a liner that is made for normal to mildly corrosive mud conditions. These liners are hardened and heat treated under strict quality control to a minimum of 60 RC hardness and a depth of 125 inches. Each liner is honed to a mirror-like finish for smooth and even wear during the life of the liner and is machined to close tolerances to assure easy installation and long life.
