Abstract: A fitting has a first housing including a first body and a second body. The first body defines a first channel and a second channel, and second body defines a third channel that is co-planar with the first channel and a fourth channel that is co-planar with the first channel. First bearings are disposed within the first channel and the third channel, where the first bearings rotatably coupled the first housing to the second housing. Additionally, second bearings are disposed within the second channel and the fourth channel, the second bearings rotatably coupling the first housing to the second housing. A plug couples to the first housing, a gasket is disposed between the plug and the first housing, and a passage is defined at least in part by the first housing, the second housing, and the plug.

Abstract: A magnetic particle inspection tool is provided including a yoke with an inspection magnet, a first magnetic member, and a second magnetic member. The inspection magnet is configured to magnetize a work piece. The first magnetic member is rotatable relative to the inspection magnet between a first position and a second position, and the inspection magnet is slidable relative to the first magnetic member. The first magnetic member and second magnetic member include a plurality of magnetic sources forming a magnetic surface with a first magnetic pattern and a magnetic surface with a second magnetic pattern. The magnetic surfaces are magnetically attracted when the first magnetic member is in the first position and repelled when in the second position.

Abstract: Typically, fluids used in fracking operations erode valve seats in the fluid end of the reciprocating pump. Thus, these valve seats must frequently be replaced by new valve seats. Accordingly, a remanufacturing process is disclosed that successively cleans and/or grinds manually or mechanically at least the carbide inserts from used valve seats until the inserts are reusable. This reduces material costs and promotes efficiency and sustainability.

Abstract: A remanufactured pinion shaft includes a salvage member secured to a replacement member. The salvage member may be formed from a damaged pinion shaft and includes first gear teeth proximate a first axial end and a first alignment member proximate a second axial end. The replacement member includes second gear teeth proximate a first axial end and a second alignment member proximate a second axial end. The first alignment member and the second alignment member cooperate to transmit rotational motion between the first salvage member and the replacement member and/or align the salvage member relative to the replacement member.

Abstract: A method for inspecting for discontinuities in a hole comprises inserting a probe including a first location having a first magnetic plarity and a second location having a second polarity into the hole, wherein the first location and second location have different magnetic polarities, creating a magnetic field between the first location and the second location within the interior of the hole, and detecting a discontinuity in the hole using the magnetic field.

Abstract: A power end frame includes a housing and a face plate secured to the housing. During use, components of the power end frame, including the housing and the face plate, are subjected to large tensile stresses. This disclosure describes a method of imparting compressive stresses in the power end frame to resist these large tensile stresses.

Abstract: A remanufactured piston for an internal combustion engine includes a crown and a skirt. A piston body includes a first piston body end within the crown and an opposite second piston body end. The crown further includes an annular crown body having an annular crown body edge. The first piston body end further includes an annular piston body edge. The annular piston body edge and the annular crown body edge form a joint, and a metallurgical bond attaches the annular crown body to the piston body at the joint.
