J55 Tubing
Tubing is the conduit used to transport crude oil or natural gas from the producing formations to the field surface facilities for processing after drilling is completed. During the extraction process, the OCTG tubing must withstand the pressure and it must be adequately strong to resist loads and deformations associated with production and workovers.
