    Exploring the Benefits of Bimetal Mud Pump Liner
    Aug 23, 2023
    Introduction   In the world of oilfield drilling mud pump, innovation never stops. One such innovation that has been making waves is the use of bimetal mud pump liners.    What Are Bimetal Mud Pump Liners?   Bimetal or bimetallic mud pump liners are currently the most widely used and one of the most used mud pump fluid end parts. It is tightly integrated by two layers, the inner sleeve and outer shell. The outer shell forging is wear-resistant and adopts centrifugal casting technology, inner sleeve is high chromium wear and corrosion resistance, heat treated to 62 HRC. The production of bimetal liners in our company strictly controls the tolerance range to ensure easy installation. The inner sleeve is with high finish, wear resistance, corrosion resistance, long service life, suitable for a variety of harsh working environments. Outer shell: 45# forged steel, tensile strength σb>610MPa, yield strength σs>450MPa, elongation §>17%, Hardness HB180-200. Inner sleeve: high chromium cast iron (centrifugal casting), annealing hardness HRC≤40, quenching hardness HRC60-67.   Benefits of Bimetallic Liners   1. Enhanced Wear Resistance: The inner sleeve of bimetallic cylinder liners is specifically chosen for its resistance to wear and abrasion. This means that the liners can withstand the high-friction environments, leading to longer service life.   2. Economic: Bimetallic cylinder liners have a lower procurement price compared to ceramic or zirconia type liner.   3. Corrosion Resistance: Many bimetallic liners feature an outer shell that is highly corrosion-resistant, ensuring longevity even in harsh operating conditions.   4. Reduced Downtime: Thanks to their durability, bimetallic liners lead to reduced downtime for maintenance and replacements, keeping drilling mud pump unit operational for longer periods.     Conclusion   The adoption of bimetallic cylinder liners represents a significant leap in the world of drilling mud pump. Their ability to combine the strength of steel with superior wear resistance makes them an attractive choice for a wide range of applications. As technology continues to advance, we can expect bimetallic cylinder liners to play an increasingly crucial role in enhancing the efficiency and longevity of mud pump industries.
