An improved multi-bolt and nut torque wrench for installing and removing bolts or nuts from flanged joints or the like which includes a plurality of torque stations having a plurality of high torque wrenches for engaging the heads of the bolts or nuts during a high torque phase of removal or installation; a plurality of low-torque motors operatively engaged with the wrenches for rotating the bolts or nuts during the low torque phase of removal or installation; a source of hydraulic fluid for driving the low-torque motors during the low-torque phase, and driving the high-torque wrenches during the high torque phase; and a mechanism for switching between the two phases depending on the torque needed.

In one aspect there is provided a pipe spinner and lifter for supporting and rotating a cylindrical member having a longitudinal axis. The pipe spinner and lifter comprises a pair of jaws that pivot about a pivot member, to allow the pipe spinner and lifter to actuate between an open configuration and a closed configuration. A plurality of rollers are mounted on the jaws, each rotatable about a rolling axis. When the pipe spinner and lifter is in the closed configuration, the cylindrical member can be rotatably captured by the pipe spinner and lifter, allowing the cylindrical member to rotate about its longitudinal axis. Preferably, the plurality of rollers are arranged in a substantially mirrored arrangement on the jaws. More preferably, the rolling axis of each of the rollers is substantially parallel to the cylindrical member's longitudinal axis.

A plug removal tool may include a mount for attaching the plug removal tool to a structure and a plug nut. Additionally, the plug removal tool may include at least one rigid arm extending between the mount and the plug nut. Further, the at least one arm may have at least one translational degree of movement and at least one rotational degree of movement.

Present embodiments relate to a riser bolt torque device that is configured to couple a first riser joint to a second riser joint to form a riser of a subsea drilling system. The riser bolt torque device includes a first arm and a second arm, multiple torque tools supported on the first arm and the second arm, and one or more actuators configured to drive the first arm and the second arm to pivot relative to one another from an open configuration to a closed configuration to enable alignment between the multiple torque tools and a flange of the first riser joint.

A torque wrench for multiple bolts or nuts comprises multiple drive spindles arranged annularly around a center and equipped or able to be equipped at the end with respective torque-applying tools, and a ratchet drive, associated with each drive spindle and driven by a hydraulic piston drive, for driving the drive spindles. The drive spindles are rotatably mounted and held in a drive block and have a drive portion at each end, which protrudes from the drive block. The drive sections of the drive spindles serve to bear the torque-applying tools on one side of the drive block, in which drive block the pistons of the piston drives are routed in cylinder housings, such that said pistons are translationally displaceable in both directions. The piston rods are kinematically connected to the ratchet lever for transferring a forward stroke movement and a return stroke movement to respective ratchet levers with pawls. The drive block has at least one fluid distribution cavity in its center area, into which open multiple fluid ducts located in the drive block, wherein a fluid connection between the fluid distribution cavity and a first fluid input of a cylinder housing is established by each fluid duct. A fluid distributor with an annular duct connected to a fluid supply duct is arranged on a flat side of the drive block as a fluid distribution cavity, into which multiple fluid ducts open, wherein a fluid connection between the fluid distribution cavity and a second fluid input of a cylinder housing is established by each fluid duct.

A tube coupling apparatus includes first and second clamping jaws that are mounted on a tool body. The clamping jaws are movable relative to each other between an open configuration in which they are receive a compressible tube connector, and a closed configuration in which they apply a compression force to compress the compressible tube coupling about one or more tube members. An actuator is arranged to move at least one of the clamping jaws to the closed configuration and a controller is operative to control the actuator. A sensor is provided that is arranged to determine a system parameter indicative of the compression force applied to the coupling by the clamping jaws and to progressively increase the compression force of the clamping jaws during a fitting operation. The controller monitors the system parameter data from the sensor and automatically controls the actuator to prevent the compression force exceeding a predetermined threshold based on the sensor data.

An apparatus is provided for producing and/or disengaging a fluid flow-capable medical threaded connection. The connection can be a Luer lock connection. The apparatus includes a first receiving device for receiving a first connecting element, and a second receiving device for receiving a second connecting element. The first receiving device and the second receiving device are rotatable relative to each other about a common screwing axis, and displaceable relative to each other along the screwing axis. The apparatus is designed to relatively move the first receiving device and the second receiving device toward and away from each other such that the first connecting element and the second connecting element can be screwed together or disengaged. An associated connecting element can be introduced into the first receiving device and/or into the second receiving device, in a radial direction relative to the screwing axis. A method is also provided.
