Abstract
The disclosure is directed at a method and system for joining pipe. The disclosure includes a coupler that includes a main and an engagement portion. The pipe includes an end portion that has a second heated part. A coupler heated part within the engagement portion is heated to a first hot working temperature while the second heated part is heated to a second hot working temperature. The coupler is then engaged with the pipe and one or both are subjected to an engagement motion to engage the heated parts.
Claims8
A method comprising:
- providing at least one pipe, said at least one pipe including an end portion at an end of said at least one pipe;
- providing a coupler including a body, the body including:
- a main portion;
- and
- an engagement portion formed to fit over the end portion, the body including a plurality of fins positioned on the engagement portion;
- providing an inert atmosphere covering the coupler and the end portion;
- energizing at least one heating element to heat a first heated part of the engagement portion to a first hot working temperature and at least one second heated part to a second hot working temperature;
- subjecting one or both of the coupler and said at least one pipe to a translocation motion, to move the engagement portion onto the end portion;
- subjecting one or both of the coupler and said at least one pipe to an engagement motion, in which one or both of the coupler and said at least one pipe move radially relative to the other;
- and
- urging the coupler against the end portion, to join the coupler to said at least one pipe.
