Abstract
A jig assembly and method of use are provided for positioning and re-rounding pipes for welding. The jig assembly comprises a first jaw assembly and a second jaw assembly which position and move a coupling onto one pipe then the second pipe for subsequent welding.
Claims15
A method of coupling pipes, comprising:
- connecting a first re-rounder to a first pipe;
- connecting at least one linear actuator to said first re-rounder, said at least one actuator being movable in a first direction which is transverse to said first re-rounder;
- connecting a second end of said at least one linear actuator to a backstop, said backstop being movable with said at least one linear actuator;
- performing a first moving step comprising moving a coupling on to said first pipe with said backstop and said at least one linear actuator;
- connecting a second re-rounder to a second pipe;
- loosening said first re-rounder;
- performing a second moving step comprising moving of said linear actuator to move said first re-rounder to engage said coupling and further move said coupling into engagement with said first and second pipes;
- and, fusion welding said coupling to said first and second pipes.

A method of joining piping, comprising:
- applying a first jaw assembly to a first pipe segment;
- applying a second jaw assembly to a second pipe segment;
- connecting a first end of a linear actuator to one of said first jaw assembly and said second jaw assembly;
- connecting a second end of said linear actuator to the other of said first jaw assembly and said second jaw assembly;
- actuating said linear actuator to move one of said pipe segments and a coupling;
- loosening one of said first or second jaw assemblies;
- positioning the coupling over adjacent ends of said first and second pipe segments by movement of said loosened one of said first and second jaw assemblies.
