HIGH CHROME SLEEVE LINERS
LINERS: HIGH CHROME SLEEVE LINERS
F&CO® OILFIELD SOLUTIONS distributes high chrome alloy sleeved liners, hardened liners, chrome plated liners and ceramic zirconia liners. We also supply authentic U.S. made rubber and urethane liner seals. All our liner products are exchangeable with OEM products and meet or exceed API-7K standards. Our liners are available in sizes ranging from 4 to 7-1/2 inches.
HIGH CHROME SLEEVE LINERS
F&CO® OILFIELD SOLUTIONS distributes chrome-iron liners are the most popular type of liners used by in the drilling fields. These cost-effective chrome-iron liners offer outstanding durability. The hybrid design of these liners combines the toughness of a high strength forged-steel outer hull with the hardness and corrosion resistance of a centrifugally cast, high-chrome-iron inner sleeve.
The outer hull or shell is manufactured from high strength carbon or alloy steel and heat-treated to provide optimum mechanical properties. CNC machined to provide exacting tolerances to keep liner concentric of the inner bore in relationship with the outer guide diameters on the hull. This reduces the possibility of misalignment on installation and provides the end user with longer liner and piston life.
The inner sleeve is made from a special, high-chrome-iron material that provides a consistent hardness in the range of 62-69 Rockwell. This means that the sleeve has excellent abrasion, erosion, and corrosion resistance. The sleeve is through hardened during heat treatment to provide high material hardness at all depths throughout the material. Our rigid quality-control standards ensure that these features are consistent on each liner manufactured at our facilities. The sleeve is manufactured to the bore tolerances specified by API or better to provide longer life by reducing gaps between the liner bore and piston.
