摘要:
The present invention is directed to a system for welding together segments of a pipeline. The system includes an external alignment mechanism for externally supporting and manipulating the orientation of pipe segments in order to align relative segments. The system also includes an internal welding mechanism for applying a weld to an interior face joint of the two abutted pipe segments. The internal welding mechanism including a torch for applying a weld, a laser for tracking the weld profile and guiding an articulating head of the torch, and a camera for visually inspecting the weld after the weld is applied.

The present application relates to a field system and methods that can be deployed in the application of pipe welding. The field system provides many embodiments relating to pipe welding systems and methods, that can be used in combination with one another, or individually. Such welding systems and methods, include, for example, internal welding systems and methods, tie-in welding system and methods, pipe inspection systems and methods, pipe handling systems and methods, internal pipe cooling systems and methods, non-destructive testing systems and methods, as well as remote interface and database systems and methods (uLog), to name a few. The application further relates to welded pipes that result from some or all of such processes.

A sprayer apparatus for coating a girth weld and a cutback region surrounding the girth weld on a steel pipe, the steel pipe having a longitudinal axis, comprises a frame, an arm, and a controller. The frame includes a roller carriage configured for rollably mounting the frame to a track mounted substantially circumferentially around the pipe, the frame also including a powered propulsion assembly for propelling the roller carriage along the track substantially circumferentially around the pipe. The arm extends or is extendable from the frame, the arm supporting a spray head. The frame also includes: a powered indexing assembly for moving the arm and the spray head longitudinally relative to the frame; a cartridge for storing a liquid to be sprayed onto the pipe via the spray head; a powered cartridge gun for forcing the liquid out of the cartridge to the spray head; and a pressurized air supply for delivering pressurized air to the spray head to control the liquid spray from the spray head. The controller is configured for controlling: the powered propulsion assembly and the powered indexing assembly; and the powered cartridge gun and/or a pressure level of the pressurized air supply to the spray head.

An internal heat exchanger (IHEX) for pipeline welding includes a drive system configured to move the IHEX into a position within at least one pipe section near a weld joint location with another pipe section. The IHEX further includes a cooling section including cooling structure configured to selectively cool one or more interior surface portions of the at least one pipe section, and a controller in communication with the cooling structure and configured to activate the cooling section when the IHEX is at the position within the at least one pipe section.
