F1300 F1600 F2200 3nb1600hl Mud Pump Cylinder Liner for Oilfield Drilling

These mud pump cylinder liners are core fluid-end spare parts tailor-made for F1300, F1600, F2200 and 3NB1600HL triplex mud pumps widely used in onshore and offshore oil & gas drilling rigs. Adopting premium bimetallic composite structure, they feature a forged 45# steel outer jacket for high pressure bearing and a high-chromium cast iron inner sleeve with hardness reaching 59–67 HRC to fend off abrasion, erosion and corrosion from sand-laden drilling mud. Precision honed inner bore guarantees tight fit with pistons, minimizing fluid leakage and sustaining stable circulation pressure up to 7,500 PSI. Fully interchangeable with OEM standard dimensions, they comply with API 7K industry specifications. Extended service life cuts frequent rig downtime and maintenance costs, perfectly fitting harsh deep well, workover and fracturing drilling scenarios for global oilfield service contractors.
