摘要： 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.

摘要： 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.
