VIEW DETAILSIn the oil and gas extraction industry, tubing and casing are two crucial types of tubular goods. Each plays a distinct role and function, and both are decisive for ensuring the safety and efficiency of oil and gas well production.
Tubing is the tubular material used in oil and gas wells, primarily serving as part of the production tubing string to transport oil and gas to the surface. Tubing generally has a smaller diameter to accommodate the flow of oil and gas.
Casing is the larger diameter tubular material installed in oil and gas wells, mainly serving to stabilize the wellbore, prevent wellbore collapse, and provide support for the subsequent tubing.
Tubing has a smaller diameter and thinner wall to facilitate oil and gas flow; casing has a larger diameter and thicker wall to provide the necessary support and isolation.
Tubing is located inside the casing and serves as the passage for oil and gas to the surface; casing is fixed to the wellbore as part of the well casing.
In the drilling process, casing is typically installed before tubing.
RockySea Petro tubing is in direct contact with oil and gas, it has higher requirements for corrosion and wear resistance; casing focuses more on strength and stability.
