1. Kingwell company introduction:

Our company is a professional manufacturer of oil drilling oilfield equipments and tools strictly according to API 7K. 

Our products mainly include all kinds of Mud pump and its spare parts.

"Serving with good Quality, Developing by advanced Science & Technology" ever was and shall always be our company 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 all kinds of oilfields and mining enterprises in China.

We offer four different types of liners as per API standard for all popular mud pumps to suit any drilling conditions, including premium chromium liners, ceramic liners, chromium-plated liners and hardened liners.

2. Detailed introduction of Kingwell mud pump 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 ironinner 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 amirror-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 steelwith 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%, hardnessis HRC180-200. The bore is plated by chrome, thickness is 0.15-0.18mm, hardnessis HRC 58-60.

4)Hardened liners: Hardened liners offer economy in a liner that is made fornormal 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.
