Carbon Steel API 5CT J55/L80 Seamless Pipe  

API 5CT CASING AND TUBING 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.
