octg stands foroil country tubular goods, which is a family of seamlessrolled products consisting of drill Pipe, casing and tubing subjected to loading conditions according to their specific application. Casing and tubing are the main components of the well construction. Casing is used to line the walls of the wellbore and prevent the wellbore from collapsing, while tubing is used to transport oil and gas from the producing formation to the surface.
Casing and tubing pipe dimensions and specifications are based on the size, weight, grade, Connection type, and wallthickness of the pipe. The size of the pipe is identified by its outer Diameter (OD). The weight of the pipe is identified by its wall thickness, which is measured in inches. The grade of the pipe is identified by its Yield strength, which is measured in pounds per square inch (psi). The connection type of the pipe is identified by its Thread type, which can be either external or internal.
a Labels are for information and assistance in ordering.
b Nominal linear masses, threaded and coupled (Column 4) are shown for information only.
c The densities of martensitic chromium steels (L80 Types 9Cr and 13Cr) are less than those of carbon steels; The masses shown are therefore not accurate for martensitic chromium steels; A mass correction factor of 0.989 shall be used.
d Mass gain or loss due to end finishing; See 8.5.
e Drift diameter for most common bit size; This drift diameter shall be specified in the purchase agreement and marked on the pipe; See 8.10 for drift requirements.
f Based on 758 mPa minimum yield strength or greater.
g Based on 379 mPa minimum yield strength.
In addition to the dimensions and specifications of the pipe, there are other important factors to consider when selecting OCTG casing and tubing pipes. These include the type of Material used, the corrosionresistance of the material, the maximum operating temperature, and the maximum pressure rating.
By understanding the key dimensions and specifications of OCTG casing and tubing pipes, oil and gas professionals can ensure that their operations are successful.
