Special Alloy Steel Casing Pipeline PSL1 PSL2 With API Threads LTC BTC STC For Oil Drilling
Oil casing pipe descriptions:
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.
Features:
1. Special alloy steel
2. Steel grades J55 K55 N80 L80 P110; L80-13Cr, P110-13Cr, Super 13Cr
3. PSL1, PSL2
