Expandable pipe joint with strengthening sleeve

摘要

A system for radially expanding and plastically deforming a first tubular 610 coupled to a second tubular 628 includes an expansion device and a sleeve 616 for maintaining portions of the tubulars in circumferential compression following expansion and plastic deformation. The system may include grooves 690 and/or ridges 692 for concentrating stresses within the joint. The tubulars may overlap. The axial spacing between the tubulars may be fixed.
