RN Lock Mandrel
FUNCTIONALITY

SECTORS
The Pragma RN Lock Mandrel is sized by the internal seal bore of the corresponding selective RN landing nipple that it locates and locks into.
XN & RN Lock Mandrels enable the positive landing and locking of subsurface flow control equipment into their matching tubing 'selective' nipple profiles. They can hold tubing pressure from either above or below.
The RN Locks typically have a higher pressure rating that the similar XN Locks and are typically used in heavier weight tubing applications.
Landing and setting the lock in the landing nipple is controlled by the R-Line running tool.
RN Lock Mandrels are factory tested in accordance with API 14L and are available in several materials meeting most well conditions. Individual technical data sheets are available upon request.
Features and Benefits
- Locates on no-go of corresponding RN landing nipple.
- Double shoulder on keys for higher working pressure.
- Can be supplied in any material to suit application.
- Suitable for bi-directional sealing.
- A device can be screwed into the bottom thread to change it to a plug, injection valve, standing valve or hanger.
Applications
Can be used for pressure testing completion strings or isolating sections of tubing.
