Upset Tubing or Upset casing pipe
Upsetting is a forging process that makes for a thicker wall on the
tube ends. Upset Tubing (EUE) is a long tubing with joint installed
in a wellbore to facilitate the extraction of oil and gas. The
tubing joints are designed to suit a certain well type, based on
the underground conditions and fluids. It acts as a conduit,
through which the produced fluids or gas get transmitted from the
bottom to the surface. Tubing joint is relatively a single length
pipe that can vary in length anywhere from 25 to 30 ft. This ideal
length allows easy production as the tubing joint is fitted with
threads on both sides and can run down through a well of any depth.

APT 5CT specified the requirements of Casing and tubing for the
purpose of oil or gas production, must be cased with material with
sufficient strength and functionality.
Oil tubing are the main parts of the well drilled construction.
They are selected for the specific conditions anticipated in a
given well. The anticipated production flow rates and economics of
the well determine tubing size, which then determines the necessary
size of each previous hole and tubular. Once the tubular size and
setting depths are determined, the wall thickness and grade of
material are then chosen by the well designer to ensure the
strength is adequate for the expected loads. API 5CT developed
specifications for three different connectors for use as casing
tubing joints: External-upset tubing and coupling (Upset
tubing),Non-upset tubing and couplings, Integral-joint tubing.
There may be the same material and grades with upsetting tubing and
non-upset tubing.The maximum difference between them are the tube
end, that is outer diameter. Non-upset tubing refers to the pipe
end without the extra thick and straight thread and collar.
Non-upset (NUE) tubing is used much less than EUE tubing. The cost
of NUE is only slightly less than EUE, and the joint strength is
substantially less. The coupling joint diameter of NUE is less than
EUE, which offers some advantages when clearance is small.
