The 2.31 ‘F’ Baker-Type Landing Nipple is a selective profile that can be located with a single ‘F’ profile nipple in the tubing string or using selective tools for locating a particular one of multiple ‘F’ profiles in a tubing string. Some operators use more than one size packing bore in a tubing string. The ‘R’ series of profile is compatible to the ‘F’. The Baker type ‘R’ is a bottom No-Go design.

Halliburton-Type: 2.313 TXN Profile Nipple – The Halliburton/Otis-type TXN profile nipples are a bottom No-Go design and are usually installed at or near the lower end of a tubing string. The TXN is non-selective and only one of the same size can be in the tubing string. Many wireline operators will locate the No-Go of a TXN profile to use as a reference point when conducting wireline operations. Standard products are manufactured from P-110 or L-80 materials.  We also manufacture from several grades of stainless steels.

Halliburton-Type: 1.875 TX Profile Nipple – The Halliburton/Otis-type TXN profile nipples are a selective design. Operators in certain circumstances have installed several ‘TX’ profiles in a tubing string. It is recommended to have 30 ft. between profiles but can be reduced to 8 ft. in “special” conditions. Our standard material is P-110 or L-80 steel but many other materials are available. The ‘TX’ can be supplied in a box to pin configuration.

All “X” and “XN” Nipples are standard EU 8 RD from alloy 110,000 yield steel. Other materials and threads are available upon request. These profiles are for standard tubing sizes. Smaller (1.00 to 1.500) are available with EU, NU, or premium threads. Large bore profile Nipples also available.
