Oil casing and oil drill pipes are different not only in their materials but also in their function. Therefore, understanding how each pipe is designed will ensure you purchase suitable materials for the job.
Oil casing is a steel pipe used inside a drilled well to protect it from soil and other contaminants. It’s much larger than the drill rod in diameter, and several layers of casing may be needed depending on the geological conditions.
Casing pipes are made from pliable yet durable and corrosion-resistant steel. They can withstand the heavy pressure caused by the weight of the soil, and they keep the well wall supported throughout the drilling process and after. Once the casing is inserted into the well, it’s cemented into place. Then when the project is complete, the single-use material is discarded.
Carbon steel makes up most oil casing materials, but higher-end materials, including nickel-chromium alloy, are sometimes preferred depending on the manufacturer.
Oil Drill Pipe
Drill pipes turn the drill bit that cuts into the ground to dig the well. These hollow pipes pull soil and rocks to the surface and help keep the drill bit from overheating. Like the casing, the drill pipe is built to withstand intense pressure from the earth around it while holding up to the drill pump’s twisting force.
Traditionally, drill pipes are made from steel; however, aluminum is becoming more common. Steel joints are used as a combination with aluminum drill pipes for added strength and stability. For jobs that require drilling miles into the ground, steel is favored, but it’s more difficult to transport than lightweight aluminum.
