Our plants are specialized in producing wide range of replacement parts for triplex mud pump(such as fluid end module, liner, piston, valve&seats, and a full line of module parts) for brand name mud pumps, including emsco, national, ideco, gardner denver, oillwell, opi wheatly, wilson, wirth, ellis willianms, skytop, brewster etc. All items are manufactured to api 7k quality standards. Module descriptions: Heat-treated and internally hardened for high durability; available in various materials to meet a wide range of applications; standard one or two-piece configuration, with designs available for pressure of 5000psi(35.1mpa), 7500psi(52.7mpa), and 10000psi(70.3mpa); discharge connections available on each side; suction connections on each side or front center. Material is 35crmoa or 40crmonn alloy forged steel. To get better fiber texture, we use electric stove for second forging, or deoxidation treatment. It is forged from three directions and the forging ratio is not less than 4.0:1.0. It can not have crack, impurity, looseness, overburns, etc. And weld is not allowed. It should be confirming to the stipulation of jb/tq252-81, and should be checked by grade3 after quenching the rough module will be rough processed, then the hull hardness is hb285-330.
