Tubing Nipple Chart
Tubing nipples, in general, are used for plumbing or piping purposes.
A nipple is a piece of pipe threaded at both ends with male threads. The tubing nipple also means a completion part that is fabricated and with a machined internal surface. An example is a landing nipple that is used in downhole completion or the process of preparing the hole bottom for injection or production in the oil industry.
Tubing Nipple Chart
The Tubing Nipple Chart shows the different data for tubing nipples such as the standard weight, size, and end connection. The table for tubing nipple can help determine the correct size, length, shape, and type of the tubing’s end connection.
The tubing nipple table shows different sizes for 18 in and 457 mm (and shorter) tubing (upset and non-upset) with their corresponding metric standards such as NPS, API, and DN. The top heading of the table also shows nominal sizes, lengths, tubing API threads, grades, wall thicknesses, and various material grades such as brass or stainless.

Understanding the Terms in the Tubing Nipple Table
End Connection specs – This column shows whether the drill pipe’s or tube’s threaded end connection is upset or non-upset and if the pipe is threaded at both ends.
Non-upset (NUE) tubing – Refers to the end of the pipe without the straight thread and extra thick collar. The NUE costs less slightly than the EUE and features less joint strength. Likewise, the NUE doesn’t undergo the upsetting (forging) process. The NUE and the EUE differ in their outer or inner diameters.
Upset tubing or EUE – Features a long tube with the joint to ease the extraction of gas and oil. Tubing joints act as a conduit in well operations and measure up to 30 feet or 9 meters. Drill pipe is used in drilling natural gas below 5,000 feet with a mud rotary. An upset drill pipe can provide a stronger and thicker drill area. Upsetting can be made in the pipe interior or exterior.
Size of Tubing Nipples
The table specifies three standard and metric designations or sizes:
- Nominal Pipe Size (NPS) ranges from 1 to 4
- The American Petroleum Institute’s sizes range from 1.315 to 4.50, except for the non-upset pipe end connection
- Diameter Nominal (DN) conforms to the International Standards Organization or ISO. Its sizes range from 25 to 100.
Tubing nipples are classified into those that have the standard weight and those with extra heavy weight. Both are 18 in or 457 mm (and shorter) upset and non-upset.
