摘要

The use of rotary expansion technology to accomplish solid (non-slotted or perforated wall) tubularexpansion goals has been recently been introduced to the Oil and Gas Industry. This rotary expansiontechnology is contrasted with the fixed cone technique. The effects of compliant versus non-compliantrotary techniques on potential applications are addressed. The effects of the expansion process onmechanical properties and corrosion resistance are presented. Reported results that characterize processeffects include full size product performance tests, corrosion rate tests and sulfide stress corrosioncracking tests. The concept of 'safe selection criteria' is introduced that ensures successful expansionprojects and final product properties.
