摘要
An expandable connection is configured such that a metal-to-metal seal is created upon expansion, even under different expansion ratios. The creation of the metal-to-metal seal can rely on a spring-back effect after expansion. A high pressure rating of the metal-to-metal seal that is created can be achieved with an oversized box face thickness. The expandable connection can also be configured to achieve a high tensile efficiency.
