DTIXN & DTIRN Landing Nipple & Lock Mandrel

DTIXN & DTIRN Landing Nipples are sized by the internal seal bore diameter and have an internal ‘no-go’ shoulder below the seal bore. They are used for single locking installations or as the bottom nipple in a production well completion tubing string. DTIXN Nipples are used in standard tubing weight applications and DTIRN Nipples are used in heavy weight tubing applications. DTIXN & DTIRN Nipples are available in most common tubing materials and with most proprietary tubing thread connections.

DTIXN & DTIRN Lock Mandrels enable the positive landing and locking of subsurface flow control equipment into their matching tubing ‘no go’ nipple profiles. They are able to hold tubing pressure from either above or below.

Landing and locking is controlled by the running tool. (Refer to DTIRX Running Tools). DTIXN & DTIRN Lock Mandrels are factory tested in accordance with API 14L and are available in a number of materials meeting most well conditions. Individual technical data sheets are available upon request.
