Oil Pipe
basic information
standard:
API SPEC 5CT, API SPEC 5B, ISO 11960
use:
Tubing: A tube inserted from the surface of the earth into the casing up to the oil layer. The tubes are connected by couplings or integrally connected. Its role is that the pumping unit transports the oil from the oil layer to the ground through the oil pipe. The main material is J55, N80, P110, and C90, T95 and other steel grades that are resistant to hydrogen sulfide corrosion.
