API 5CT N80 Casing Tubing is a API 5CT Oil Casing Pipe & mainly used for oil well drilling. it is available as short thread type and long thread type supplied with their couplings.
API 5CT N80 Casing Tubing serves to transport both crude oil and natural gas from oil and gas layer to the surface pipeline after drilling is completed. It is able to bear the pressure produced by the exploitation process. After the outer surface is coated with a protective layer, the tubing is marked in accordance with the API 5CT standard and strapped with metal belt.

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.
