Liner Hangers With Optimized Installation
The Dril-Quip XPak® De is a premium liner hanger designed specifically to deploy large OD liners through the restricted ID of a subsea wellhead and eliminate the need for supplemental adapters.

Engineered For Efficiency
Subsea well designs historically utilize sub-mudline supplemental casing hanger systems to deploy large casing strings. These sub-mudline systems are inefficient, do not offer optimal installation parameters and have a history of operational difficulties and failures.
XPak® De enables 18" and 16" liners to be deployed and set as a true liner hanger; anywhere within the 22" casing string and without the need for contingency target joints or pre-installed adapters.
