Various Steel Grades Seamless Casing Pipe Quality Alloy Steel For Oil Well Construction
Casing pipe description:
Casing pipe is most often used in underground construction projects to encase or protect utility lines
from being damaged.
Once a well has been drilled, if it is to become a production well, the well must undergo completion.
While drilling a well cuts through the rock formations and allows drilling engineers to reach the
reservoir below, the raw sides of the well cannot support themselves. Similar to the bones of your
spine protecting the spinal cord, casing is tubing that is set inside the drilled well to protect and support the wellstream.
