OCTG: Oil country tubular goods is the classification used for a variety of downhole products
API 5CT P110 Casing Tubing can be widely applicable to petroleum, construction, shipbuilding,
smelting, aviation, electric power, food, paper, chemical industry, medical equipment, boilers,
heat exchangers, metallurgy and so on.
P110 Casing is placed downhole to provide structural integrity to the wellbore and must withstand
external-collapse pressure from rock formations and internal-yield pressure from fluid and gas. It must
also hold its own deadweight and withstand the torque and transaxial pressure placed on it while running
downhole.
