Liners

HIGH CHROME LINERS
TEAMAO’s high chrome liners are made with a high chrome iron sleeve in a forged steel hull. The bore hardness is 60 to 67 on the Rockwell C scale, while the hull has a high tensile strength of more than 90,000 psi, Combining the characteristics of chrome with state-of-the-art manufacturing, the liners can withstand mud pressures of up to 10,000 psi. The life of our high chrome liners have proven to reach on average more than 800 hours of service. Such performance has earned TEXMAO’s high chrome liners an outstanding reputation for extended service operations.




CERAMIC LINERS
TEAMAO’s ceramic liners offer longer run times and lower or zirconia operating costs when compared to chrome iron liners. The ceramic sleeve material is manufactured from alumina or zirconia oxide, known for its wear resistance and proven run times in all types of operating conditions. The outer hull material for large bore liners in manufactured from alloy steel to increase yield strength and aid in fatigue resistance. Ceramic liners are corrosion resistant and have a smoother surface finish which helps reduce friction and heat.





CHROME-PLATED LINERS
TEAMAO offers chrome-plated liners made from premium forged steel with a chrome-plated bore. The chrome-plated liners have hardening characteristics of 58 to 62 Rockwell C, which makes them an economical yet durable solution.
 




HARDENED STEEL LINERS
TEAMAO’s hardened steel liners are made from premium seamless steel tubes or premium forged steel in which the bore is carburized and quenched. This process creates a hardened layer at a Rockwell C scale hardness of 58 to 62, which yields excelient wear characteristics.
