LANDING NIPPLES are devices which are integral
parts of the tubing string. They are manufactured with internal
profiles which provide predetermined locations in the tubing string
where downhole control devices can be landed and retrieved by wireline
or coiled tubing.
All Tube-AlloyTM landing nipples
meet the requirements of API specifications 14A and Q1.
Tube-Alloy landing nipples are designed to accept industry standard
locking devices of major manufacturers. Finite element analyses
are available to confirm this compatibility.
The following types of landing nipples are available from Tube-Alloy:
|
SWSTM -
|
