PRODUCT DETAILS
Description
Tubing is a relatively small-diameter pipe that is run into a wellto serve as a conduit for the passage of ol and gas to the field surfacefaciities for processing. Tubing must be adequately strong to resist loads and defomations associated wth production and workovers
Further, tubing must be sized to support the expected rates of production of oil and gas.
Sizes and Materials
Tubing pipes are manufactured in seamless and welded execution, in the size range of 1.050 to 5 1/2 inches (consut this article to see the AP5CT tubing pipes stzes) and in the following material grades: H-40, J-55, K-55, N-80, L-80, C-90, T-95, P-110, Q-125
End Connections
The main types of connections for tubing pipes are NUE (non-upset), EUE (exteral upset) and premium. Corrosion resistance under sour service conditions is a very important OCTG characteristic, especially for casing and tubing
