This invention relates to a plugging machine and a rigid tube provided with a stationary disc integral with the bottom of the tube and oriented almost orthogonal to the tube, with a movable disc paired with the stationary disc. A sealing ring of a resilient material is located between the discs and compressed when the movable disc is pressed against the stationary disc to adhere to an inner surface of the pipeline. The sealing ring is coaxial with respect to the pipeline. The movement of the movable disc is determined by raising or lowering a control rod within the tube by means of sloping sliders made in the lower portion of the rod which engage in respective grooves, likewise sloping, made in an axial shank associated with the movable disc and sliding inside an axial opening of the stationary disc. A component of a force is generated which is parallel to the axis of the discs. The axis is raised or lowered by rotation of a threaded ring engaging in a threading mate at the top of the rod.

A large-gap-seal ("LGS") assembly (30) and methods for its assembly and use are described. The LGS assembly (30) has an elastomer core (50) surrounded by adjoining structural segments (70). Non-adjoining gap segments (60) are located on the sidewall surfaces (55) of the elastomer core (50), with each gap segment (60) approximately centered beneath the edges of two adjoining structural segments (70). The gap segments (60) are exposed by the spaces that form between the structural segments (70) when the LGS assembly (30) is activated. Exposing the gap segments (60) rather than the elastomer core (50) protects the elastomer core (50) from damage and preserves the integrity of the seal between the isolation tool (20) and the inner wall of the pipeline.
Embodiments of a multi-diameter foam pig include a first set of radially spaced-apart, longitudinally extending, slots located toward a nose end of the pig and a second set of radially spaced-apart, longitudinally extending, slots located toward a tail end. Each set of slots ends at a band section of the pig so that, together, the two sets of slots do not traverse the entire length of the pig. A standard-length unit version of the foam pig includes only the first set of slots. A set of shorter, intermediate slots, offset in a circumferential direction from the first and second set of slots and partially overlapping those slots, may be included on the band section. Because of the slots, and because of open cell foam, the foam pig decreases or increases in diameter as it enters a different diameter run than the run just traveled.

A metal seal fitting for use on a pipe or pipeline includes at least one metal seal ring having a C-profile which houses a spring and is arranged concentric to, and outside of, a tap diameter of the access connection. The seal ring is double-curved so that it conforms to a pipe-facing side of the fitting. A surface of the pipe is prepared to receive the seal and, as the fitting is being secured to the pipe, the seal is activated and spring-energized. In its final sealing state, the seal is not compressed passed its deformation point and maintains its spring-back capability. After the fitting is removed from the pipe, the seal may be re-used. The metal seal fitting is suited for applications requiring a high integrity seal and can be used in high pressure, high temperature, and highly corrosive environments which are not well-suited for elastomeric seals.

Thick, long seam welding system and method for distortion control and non post weld heat treatment of pipeline hot tap fittings
A method for limiting fitting distortion when welding a fitting to an in-service pipeline—where the fitting includes a thick, longitudinally extending, seam located between fitting halves—involves welding, on each side of the fitting, a middle third section of the seam in a pyramid-like fashion using an inward progression starting from an end of the middle third section along a profile of a seam bevel, and welding outer third sections of the seam using an outward progression from an end adjacent to the middle third section along a profile of the seam bevel. The welding of each of the three sections per side includes a temper bead welding technique of at least two layers to provide stress relief in lieu of traditional post weld heat treatment.

A system and method for non-destructive, in situ, positive material identification of a pipe selects a plurality of test areas that are separated axially and circumferentially from one another and then polishes a portion of each test area. Within each polished area, a non-destructive test device is used to collect mechanical property data and another non-destructive test device is used to collect chemical property data. An overall mean for the mechanical property data, and for the chemical property data, is calculated using at least two data collection runs. The means are compared to a known material standard to determine, at a high level of confidence, ultimate yield strength and ultimate tensile strength within +/−10%, a carbon percentage within +/−25%, and a manganese percentage within +/−20% of a known material standard.

This inventions relates to a plugging machine and a rigid tube provided with a stationary disc integral with the bottom of the tube and oriented almost orthogonal to the tube, with a movable disc paired with the stationary disc. A sealing ring of a resilient material is located between the discs and compressed when the movable disc is pressed against the stationary disc to adhere to an inner surface of the pipeline. The sealing ring is coaxial with respect to the pipeline. The movement of the movable disc is determined by raising or lowering a control rod within the tube by means of sloping sliders made in the lower portion of the rod which engage in respective grooves, likewise sloping, made in an axial shank associated with the movable disc and sliding inside an axial opening of the stationary disc. A component of a force is generated which is parallel to the axis of the discs. The axis is raised or lowered by rotation of a threaded ring engaging in a threading mate at the top of the rod.

Embodiments of a multi-diameter foam pig (10) include a first set of radially spaced-apart, longitudinally extending, slots (11A) located toward a nose end (13) of the pig and a second set of radially spaced-apart, longitudinally extending, slots (11B) located toward a tail end (23). Each set of slots ends at a band section (15A; 15B) of the pig so that, together, the two sets of slots do not traverse the entire length of the pig. A standard-length unit version of the foam pig includes only the first set of slots (11A). A set of shorter, intermediate slots, offset in a circumferential direction from the first and second set of slots and partially overlapping those slots, may be included on the band section. Because of the slots, and because of open cell foam, the foam pig decreases or increases in diameter as it enters a different diameter run than the run just traveled.

SYSTEM AND METHOD OF PREVENTING FLOW BLOCKING WHEN USING AN AUTOMATED PIG LAUNCHER
A flow assurance system and method includes procedures to query current valve states and determine the likely effect of new valve states on product flow when using an automated pig launcher. The system and method allows for modulating the mainline bypass valve, kicker valve, and isolation valve between fully opened and fully closed states; prevents flow blocking of the pipeline during this modulation; enables new and different, as well as a broader range of, pig launching options for an automatic pig launcher; and integrates with existing automatic pig launchers.
This inventions relates to a plugging machine (100) and a rigid tube (2) provided with a stationary disc (3) integral with the bottom of the tube (2) and oriented almost orthogonal to the tube (2), with a movable disc (4) paired with the stationary disc (3). A dealing ring (50) of a resilient material is located between the discs (3, 4) and compressed when the movable disc (4) is pressed against the stationary disc (3) to adhere to an inner surface of the pipeline (200). The sealing ring (50) is coaxial with respect to the pipeline (200).

A pig launcher/receiver includes a fluid distribution grid arranged above a floor of the pig launcher/receiver's barrel to define a fluid chamber between the floor and the fluid distribution grid. The distribution grid has a plurality of ports arranged to form jets that discharge at least a portion of the fluid which enters the fluid chamber. A predetermined number of the ports are inclined relative to vertical and in a direction opposite a closure door of the barrel. The fluid distribution grid, which is preferably semi-circular shaped, can be a permanent weldment, bolted on, or removable. When used in launching a pig, the ports provide a differential pressure that lifts the pig and overcomes friction as the pig moves forward. Because a number of the ports are blocked by the sealing elements (cup or disc) of the pipeline pig, the number of pigs residing in the launcher/receiver can be determined.

A pipeline pig (10) that can traverse dual- or multiple-diameter pipes or pipelines has collapsible and expandable sealing elements (20) that support the pig, provide a sliding (dynamic) seal with the pipe wall, and maintain the necessary pressure for driving or cleaning as the elements collapse and expand. The sealing elements (20) each have an internal cavity (21) sized to house a first volume of a fluid and a reservoir (20) sized to house a second volume of the fluid. The cavity (21) and reservoir (29) are arranged so that a portion of the volumes of the fluid can move between each. An accumulator (30) maintains a pressure of the first and second volumes of the fluid so that regardless of the sealing element's current size, or whether the element (20) is transitioning between sizes, the element (20) can maintain a sliding seal engagement with the pipe wall (W) and perform the primary function of driving or cleaning (or both).
