Oil country tubular goods is the classification used for a variety of downhole products. SeAH produces ERW casing and tubing for downhole oil and gas applications. 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.Tubing is placed within the casing. It is used to transport oil and gas from the source rock to the wellhead. Benefiting from over fifty years of experience, SeAH sets itself apart by excelling in quality control, innovation, and competitive pricing.
