Rich oiltools supplies four different type of liners for all popular mud pumps to suit any drilling condition, which include Premium Chromium Liners, Ceramic Liners, Chromium-plated Liners and Hardened Liners.

A).Premium Chromium Liners
Premium liners combine the strength of a forged steel outer 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 62 HRC(Hardness Rockwell C). Premium liners are made for superior performance under tough corrosive and abrasive conditions.

B).Ceramic Liners
Ceramic liners combine the strength of a forged steel outer 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 Ziconia exhibits better impact strength, higher hardness and be honed to finer surface finishes than alumina.

C).Chromium-plated Liners
Chrome-plated liners made from premium forged steel with the core plated by chrome. The chrome-plated liners have hardening characteristics of 58 to 62 HRC(Hardness Rockwell C). 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.

D).Hardened steel Liners 
Hardened steel liners are made with premium seamless steel tube or Premium forged steel, in which the bore is carburized and quenched, creating a hardened layer with hardness of 58 to 62 HRC(Hardness Rockwell C).
