Patent number: 11725463Abstract: A cold worked and spinodally-hardened copper alloy comprising from about 8 to about 20 wt % nickel, and from about 5 to about 11 wt % tin, the remaining balance being copper, and having a 0.2% offset yield strength of at least 75 ksi, is used to form a sucker rod coupling or subcoupling. Each coupling is formed from a core having two ends, each end having an internal thread. These box ends engage the pin of a sucker rod or other rod. The exterior surface of the core includes grooves running between the two ends.Type: GrantFiled: April 15, 2021Date of Patent: August 15, 2023Assignee: Materion CorporationInventors: William D.

Patent number: 11459832Abstract: A coupling for joining a downhole pump to a sucker rod string is disclosed. The coupling includes a core having a first end, a central portion, and a second end. The first end and the second end each have an end surface. The first end tapers linearly inwards from the central portion to the first end surface. The second end has a rounded edge along the second end surface. The coupling is made from a spinodally-hardened copper-nickel-tin alloy and has a sliding coefficient of friction of less than 0.4 when measured against carbon steel.Type: GrantFiled: November 10, 2020Date of Patent: October 4, 2022Assignee: Materion CorporationInventors: William D.

Patent number: 11174688Abstract: A sucker rod guide having low friction and high wear resistance is disclosed herein, along with a fluid extraction system comprising the same. At least a part of the exterior surface of the sucker rod guide is formed from a cold worked and spinodally-hardenable or spinodally-hardened copper alloy comprising from about 5 to about 20 wt % nickel, and from about 5 to about 10 wt % tin, the remaining balance being copper, and having a 0.2% offset yield strength of at least 75 ksi. The guide includes a smoothbore adapted to surround and engage the surface of a sucker rod. The exterior surface of the guide can include grooves miming between the two ends. In particular embodiments, the guide is made by joining together two identical guide segments. In other embodiments, the guide is a single integral piece molded around a sucker rod.Type: GrantFiled: December 28, 2018Date of Patent: November 16, 2021Assignee: Materion CorporationInventors: Fritz C.

Patent number: 10049785Abstract: An electrically conductive wire for deep water transmission includes a first wire portion and a second wire portion. The first wire portion makes up one end of the wire, and is formed from a first metal. The second wire portion is formed from a second metal. The first metal has a higher ultimate tensile strength than the second metal. The first wire portion is used to support the weight of the second wire portion, thereby allowing the electrically conductive wire to be used in underwater or subsea power cables which may be freely suspended from their origin for providing electricity to electrical devices located in deep water or ultra-deep water.Type: GrantFiled: July 27, 2017Date of Patent: August 14, 2018Assignee: MATERION CORPORATIONInventors: William D.
