Techniques for implementing and/or operating a pipe deployment system including pipe deployment equipment, in which a pipe drum having spooled thereon a pipe segment is to be loaded on the pipe deployment equipment, and a pulling device to be secured to an unspooled section of the pipe segment to enable pulling force to be exerted thereon. The pulling device includes a first device leg, a second device leg parallel to the first device leg, and a device base extending between and secured the first device leg and the second device leg such that the device base is perpendicular to the first device leg and the second device leg and the device base is raised relative to a bottom surface of the first device leg and a bottom surface of the second device leg, in which the unspooled section of the pipe segment is to be disposed on the device base.

An attachment that is configured for attachment to an arm of a piece of heavy construction equipment. The attachment is configured to rotate a section of pipe during break-out (i.e. disconnection or disassembly) from another section of pipe and/or make-up (i.e. connection or assembly) with another section of pipe. The attachment is configured to break the joint or torque the joint, unthread or thread pipe, and lift the pipe under the power of the heavy construction equipment.

A pipe mount for connecting pipe sections is disclosed. The pipe mount comprises a sliding member movably attached to a plumbing arrangement element. The sliding member extends in the vertical direction of the plumbing arrangement element, and it is vertically movable between an extreme position and a second position. The pipe mount further comprises at least one pipe bracket for securing the pipe sections onto the sliding member. A system and a method for connecting pipe sections are also disclosed.

A pulling and alignment system for flanged components has pairs of flange attachments fixed to respective flanges of components that are to be pulled together and aligned for coupling. A puller device is supported by a flange attachment of each pair. A flexible elongate pulling link extends between the flange attachments of the pair and is engaged by, and movable relative to, the puller device to act in tension between those flange attachments. Each flange attachment is a flange extension that comprises an arm cantilevered from a mounting to extend beyond the flange and to hold the pulling link outboard of the flange. The pulling link is an articulated rod having a longitudinal series of rigid elements, each of those elements being pivotably coupled to at least one other of those elements.

A pipe joining method includes a moving of a first transport trolley with a loaded first pipe and a second transport trolley with a loaded second pipe forward, a joining of one end of the first pipe to another end of a rearmost pipe of a pipeline, a lifting of another end of the first pipe, a moving of the first transport trolley and the second transport trolley backward, a drawing of the first transport trolley from beneath of the first pipe to the near side, a removing of a coupler to separate the first transport trolley and the second transport trolley, a moving of the first transport trolley backward, a drawing of the first transport trolley below the second pipe loaded on the second transport trolley, and a moving of the second transport trolley forward with the first transport trolley.

A header delivery system and method for performing a pigging operation on a process tube connected to a header pipe. The header delivery system is insertable in the header pipe and has a launcher pipe for launching an inspection or cleaning tool to the process tube. A tube coupler for coupling to the process tube and a bumper are connected to the launcher pipe. A jack apparatus is configured to position the tube coupler and the bumper. A wedge assembly is connected to the launcher pipe and has a first actuating wedge and a first extension wedge. A first linear actuator is connected to the first actuating wedge and is configured to move the first extension wedge and the tube coupler mount apart from one another to position the tube coupler and the bumper from a retracted position to an extended position.
