Tubing-OCTG
Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling completed. Tubing-OCTG is made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except the "upsetting" process is applied to thicken the pipes.
