  • Pipe coupling make up assembly
    Patent number: 10094495
    Abstract: A pipe coupling make up assembly and a method of making up a pipe coupling between tubular sections at a well. A first tubular section in a tubular string at the well is gripped and supported in the assembly. A second tubular is supported and moved to locate a first end of the second tubular section into an expanded first end of the first tubular section. A swaged die is arranged around the first tubular section and forced along the first tubular section towards the second tubular section. This causes the expanded first end to move radially inwards under elastic and plastic deformation and create a metal to metal seal between the first ends of the first and second tubular sections.
