Our company is a professional manufacture of oil drilling equipments strictly according to API 7K & 4F. Our products mainly include oil drilling rig, solids control system, drawworks, rotary table, triplex single acting mud pump, utilized mud pump package, centrifuge, shear pump, shale shaker, centrifugal pump and their spare parts.
"Serving on Quality, Developing by Science & Technology" ever was and shall always be our firm belief. And customers satisfaction shall always be our permanent goal.
Good quality, competitive price and excellent service have won us the foundation for our good cooperation with our customers. Now our products are being used by dozens of oilfields and mining enterprises in China. And also our products have been exported to customers in USA, Canada, Brazil, Kazakhstan, Rumania, East Asia, Southeast Asia etc..
We offer four different types of liners as per API standard for all popular pumps to suit any drilling conditions, including premium chromium liners, ceramic liners, chromium-plated liners and hardened liners. 1)Premium Chromium Liners: Premium liners 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. 2)Ceramic Liners: 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: 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.
We survive for our customers. Therefore, any information from you would be highly cherished! Expecting
