Patent number: 10844669Abstract: A threaded joint for joining tubes used especially in the field of OCTG (Oil Country Tubular Goods), such as pipes in gas or oil production and/or casings when drilling wells can include a pin and a coupling, or box, having an end surface not facing against any surface of the pin when the joint is made-up. Following make-up of the joint, first sealing surfaces of the pin and box mate to form an internal metal-to-metal seal, and second sealing surfaces of the pin and box mate to form an external metal-to-metal seal, where the internal and external seals are defined by contact between one toroidal surface and one frusto-conical surface.Type: GrantFiled: November 24, 2010Date of Patent: November 24, 2020Assignee: TENARIS CONNECTIONS B.V.Inventors: Gaston Mazzaferro, Gabriel E. Carcagno, Tatsuo Ono, Nestor J. Santi

Patent number: 9004544Abstract: A threaded joint comprises a coupling, a first pin, and a second pin, wherein the thread of the first pin has a pitch different from the pitch of the thread of the second pin. The extremities of the pins have slanted contact surfaces of complementary shape that make mutual contact after make-up of the joint. The slanted common plane of contact of both pins has an angle to the plane perpendicular to the longitudinal axis of the joint which is greater than 0°. In an alternative embodiment the contact surfaces of the pins are split into two staggered planes and comprise a seal in-between.Type: GrantFiled: April 22, 2010Date of Patent: April 14, 2015Assignee: Tenaris Connections LimitedInventors: Gabriel E. Carcagno, Alfredo Francisco Quiroga

Patent number: 8052173Abstract: A threaded metallic joint has the thread surface of pin (100) and box (200) covered with a coating comprising a first layer (24) laid on the overall surface of the pin member (100), and a second layer (25) laid on part of the surfaces of either one of the pin or box members. In a first aspect, the coating comprises a first layer with high friction and anti-seize properties laid on the overall surface of the pin member (100), and a second layer (25) with low friction properties laid on specific parts of the surfaces of either one of the pin or box members. Preferably the specific surfaces are those which are in reciprocal radial contact during make-up until pin and box reach the point where shoulders (9, 10) abut. The second layer may contain polytetrafluoroethylene (PTFE). In a second aspect the first layer with a high friction and anti-seize properties laid on the overall surface of the box member (200).Type: GrantFiled: November 29, 2006Date of Patent: November 8, 2011Assignee: Tenaris Connections LimitedInventors: Gabriel E.

The pin can have a pin threaded portion between a first sealing surface distal of the pin threaded portion and a second sealing surface proximate to the pin threaded portion. The coupling or box can have a box threaded surface between a first sealing surface and an abutment shoulder located proximate to the box threaded surface and a second sealing surface distal of the box threaded surface.Type: ApplicationFiled: November 24, 2010Publication date: June 9, 2011Applicant: TENARIS CONNECTIONS LIMITEDInventors: Gaston Mazzaferro, Gabriel E.

Patent number: 7506900Abstract: A threaded joint for pipes comprising at least one seal of the metal-metal interference type arranged externally to the female thread. The joint has an extension of the box beyond the seal which produces an elastic tightening band effect on the seal so that excessive interference on the seal is not necessary, thus favoring correct making up.Type: GrantFiled: February 16, 2006Date of Patent: March 24, 2009Assignee: Tenaris Connections AGInventors: Gabriel E.

Patent number: 7464449Abstract: A radially expandable sealed tubular joint for use in oil and gas wells having a pair of radially expandable tubular elements each having threading at a free end thereof and coupled to one another to form a flush joint connection, the threading including hooked incomplete threads located at least adjacent the free ends, and a sealing substance extending between and adhering to the threading of one element and the threading of the other element, wherein after a radial expansion of the coupled pair of elements the sealing substance remains extended between and adhered to the threading of one element and the threading of the other element. The sealing substance is either a greaseless elastomeric sealant coated on one or both of the pair of elements or a pure metal applied to each of the pair of elements.Type: GrantFiled: October 13, 2006Date of Patent: December 16, 2008Assignee: Tenaris Connections AGInventors: Nestor J Santi, Gabriel E Carcagno

Patent number: 7284770Abstract: A pipe thread protector includes a case, a first seal member, and a second seal member. The case is attachable to an end of a pipe to protect a threaded region of the pipe. The case has a cylindrical or frustoconical portion having threads over at least a portion of its length to engage the threaded region of the pipe, and an annular end portion configured to abut a distal end of the pipe. A first seal member is disposed at the cylindrical portion of the case, and a second seal member is disposed at the annular end portion of the case. At least one of the first and second seal members (i) is detachable from the case, and (ii) comprises a material different than a material of the case.Type: GrantFiled: January 31, 2005Date of Patent: October 23, 2007Assignee: Tenaris Connections AGInventors: Diego Dell'erba, Gabriel E.
