Patent number: 9964245Abstract: A swivel joint has uniform ball bearing requirements for all bearing races. The swivel joint has a male connector and a female connector that coaxially interconnects and swivel relative to each other while still maintaining a high pressure seal. Each connector has three bearing races to form three sets of bearing races, each of which supports the same number of ball bearings. The circumference of the main set of races are enlarged by less than the diameter of one ball, so it is impossible to add another ball to the coupled male and female connectors of the swivel joint.Type: GrantFiled: October 27, 2014Date of Patent: May 8, 2018Assignee: S.P.M.

Patent number: 9638337Abstract: A plug valve including a valve body having an inlet port, an outlet port and a central chamber extending between the inlet port and the outlet port. The valve also includes an inlet seal segment within the central chamber and includes a bore extending therethrough and aligned with the inlet port. An outlet seal segment is disposed within the central chamber having a bore extending therethrough and aligned with the outlet port. A plug member is disposed in the central chamber and is moveable between an open position, to facilitate fluid flow through the plug valve, and a closed position, to block fluid flow through the plug valve. First and second side segments are disposed between and interlocked to the inlet and outlet seal segments to encircle the plug member. The side segments are tensioned to preload the seal segments against the plug member to prevent the flow of fluid between the seal segments and the plug member.Type: GrantFiled: August 7, 2015Date of Patent: May 2, 2017Assignee: S.P.M.

Publication number: 20170108153Abstract: A fitting is disclosed that includes a body; a first flow passage extending through the body; and a second flow passage formed in the body to intersect the first flow passage. The first and second flow passages define first and second longitudinal center axes, respectively. In an exemplary embodiment, the fitting forms a portion of a manifold assembly of a frac system. In one aspect, the fitting is formed by a manufacturing process such that the body has a parting plane that is offset from, and parallel to, the first longitudinal center axis. The fitting may have a first varying wall thickness defined between the first flow passage and the external surface; and a second varying wall thickness defined between the second flow passage and the external surface. In another aspect, a curved surface is formed in the body at the intersection between the first and second flow passages.Type: ApplicationFiled: October 10, 2016Publication date: April 20, 2017Inventors: Brian Witkowski, Nadiya Fuller

Patent number: 8978695Abstract: A check valve assembly has a body having a central cavity intersected by upstream and downstream flow passages. A seat is secured by a threaded engagement in the upstream flow passage. An access bore intersects the cavity and has a support shoulder formed in it. A holder is supported on the support shoulder. A flapper is pivotally secured to the holder and located in the cavity for movement between an open position and a closed position blocking flow through the seat. A straight edge portion in the access bore engages a straight edge portion of the holder to prevent rotation of the holder. A fastener extends through a hole in the support shoulder into engagement with the seat to prevent rotation of the seat.Type: GrantFiled: September 10, 2012Date of Patent: March 17, 2015Assignee: S.P.M.

Publication number: 20130037125Abstract: A pressure relief valve assembly includes a body having a passage extending therethrough. The body includes an upstream end adapted to be connected to a source of fluid pressure, an intermediate portion, and a downstream end having a downstream exit. A rupture disk is mounted in the passageway and blocks the fluid pressure of the source from the downstream end. In operation, the rupture disk configured to rupture above a predetermined differential fluid pressure. A catcher is disposed in the passage downstream of the rupture disk. The catcher generally includes a disk portion with at least one opening sized to prevent passage of the rupture disk through the catcher in response to a rupture disk failure while simultaneously allowing fluid flow through the catcher to the downstream exit.Type: ApplicationFiled: August 10, 2012Publication date: February 14, 2013Applicant: S.P.M.
