High Quality API 5CT Casing And Tubing Pipe

Introduction of casing and tubing pipe

Oil casing is used to create a good flow channel for oil or natural gas from underground reservoirs to the surface, to protect the well wall, isolate fluids in each layer, and facilitate the layered extraction of oil and gas wells.

Tubing pipe is a pipe that is inserted into the casing of an oil well, mainly used to transport oil from the bottom of the well to the surface. The tubing joint general include two types: EU(external upset) and NU(non-upset).
