Oil and gas

Oil Country Tubular Goods, OCTG

​​Tubing hanger

The most common term used for components in the oil and gas industry is OCTG. Their purpose can vary: pipes can be used either to produce or inject gas, oil, water, steam, etc. and depending on their application, they can be categorized as casing or tubing. The casing serves as a protective layer which helps maintain the durability of the well against inside or outside contaminants, whereas tubing is used to inject or produce fluids.

Drill pipes and couplings constitute the remaining main components. Drill pipes are heavy seamless tubes that rotate the drill bit and circulate drilling fluid, while couplings are internally threaded cylinders for joining two lengths of threaded pipe.

Main components in OCTG

  • Casings
  • Tubes
  • Couplings
  • Drill pipes
