Patent number: 11466800Abstract: A tubular connection, method for connecting tubulars, and a coupler for connecting together tubulars, of which the tubular connection includes an inner body including a bore, external threads, a tapered torque nose, and a radially-facing sealing surface. The connection also includes an outer body including a bore in communication with the bore of the inner body, internal threads configured to engage the external threads of the inner body, a tapered torque-stop surface that engages the tapered torque nose, and a radially-facing sealing surface that forms a seal with the radially-facing sealing surface of the inner body. The external threads, the internal threads, or both include at least one kick-out feature including at least one rounded or chamfered corner thereof.Type: GrantFiled: September 20, 2018Date of Patent: October 11, 2022Assignee: CERTUS ENERGY SOLUTIONS, LLCInventors: Patrick Williamson, Michael G.

Patent number: 11028948Abstract: A tubular connection includes an inner body having a bore, external threads defining external thread surfaces, a torque nose, and a radially-facing sealing surface, and an outer body having a bore in communication with the bore of the inner body, internal threads defining internal thread surfaces and being configured to engage the external threads of the inner body, a torque-stop surface that engages the torque nose, and a radially-facing sealing surface that forms a seal with the radially-facing sealing surface of the inner body. The external threads define a first radius between two of the external thread surfaces, the internal threads define a second radius between two of the internal thread surfaces, the external threads where the first radius is defined being configured to engage the internal threads where the second radius is defined, the first and second radii being mismatched.Type: GrantFiled: May 14, 2018Date of Patent: June 8, 2021Assignee: CERTUS ENERGY SOLUTIONS, LLCInventors: Patrick Williamson, Michael G.
