API SPEC 7K F1300 FLUID END MODULE for MUD PUMP

FLUID END MODULE 

Heat-treated and internally hardened for high durability; available in various materials to meet a wide range of applications; standard one-or and/or two-piece configuration, with designs available for pressure of 5000, 7500, and 10000 psi(351,527,and 703kg/cm2); discharge connections available on each side; suction connections on each side or front center.

Adapt most third party fluid-end modules to the mud pumps, eliminating the need for drilling contractors to stock fluid end parts from several manufacturers, Supply heat-treated, internally hardened forged alloy steel modules, if the drilling contractor doesn’t specify third party fluid ends.

Material is 35CrMoA or 40CrMoNn alloy steel forging. To get better fiber texture, we use electric stove for second forging, or deoxy 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, over burns, etc. And weld is not allowed. It should be confirming to the stipulation of JB/TQ252-81, and should be checked by Ⅲ grade. After quenching the rough module will be rough processed, then the hull hardness is HB285-330.

Mechanical property: σb ≥850MPa, σs≥670MPa, δ≥5%,ψ≥30%.

The two1:6(1:12) taper hole rolling treatments are checked by ring gage. Its contact area has continuous distribution on the circumference. The contact area is not less than 75% .The line of intersection of all cylindrical surface of the hull are facetted obtuse angle by hand or grinding wheel ,forming a circumference R≥8.Test pressure is 49Mpa, keep pressure 1 hour, pressure can not be reduced. Finished products have crack detection report.
