Abstract
A method of coupling tubular members.
Claims16
A method of coupling a first member to a second member, comprising:
- forming a first set of coupling slots in the first member;
- forming a second set of coupling slots in the second member;
- aligning the first and second pairs of coupling slots;
- inserting coupling elements into each of the pairs of coupling slots;
- and
- removing the coupling elements from the pairs of coupling slots by pressurizing a chamber defined between the first and second member and displacing the first member relative to the second member in the axial direction.

- forming a first set of coupling slots in the first member;
- forming a second set of coupling slots in the second member;
- aligning the first and second pairs of coupling slots;
- inserting coupling elements into each of the pairs of coupling slots;
- and
- removing the coupling elements from the pairs of coupling slots by:
- pressurizing an annular chamber defined between the first and second member;
- removing the coupling elements from the pairs of coupling slots when the operating pressure within the annular chamber defined between the first and second member exceeds a predetermined amount;
- displacing a retaining sleeve when the operating pressure within the annular chamber defined between the first and second member exceeds a predetermined amount;
- and
- displacing the first member relative to the second member in the axial direction.

A method of coupling a first member to a second member, comprising:
- forming a first set of circumferentially spaced apart coupling slots in the first member;
- forming a second set of circumferentially spaced apart coupling slots in the second member;
- aligning the first and second pairs of coupling slots;
- inserting coupling elements into each of the pairs of coupling slots;
- resiliently biasing the coupling elements into each of the coupling slots;
- defining an annular chamber between the first and second members;
- positioning a retaining sleeve that defines one or more longitudinal passages within the annular chamber for retaining the coupling elements within the coupling slots;
- defining a pressure chamber between the retaining sleeve and one of the first and second members;
- and
- allowing the coupling elements to be removed from the coupling slots by displacing the retaining sleeve when the operating pressure within the pressure chamber exceeds a predetermined amount and displacing the first and second members relative to one another in an axial direction.
