Product Description

Product Description

API 5CT Oil Casing Steel Pipe
    Oil casing pipes, also known as production casings. It is the last layer of casing in the oil and gas well casing process, from the wellhead down to below the oil and gas layer.The depth of the casing casing is basically the depth of the well.
    The function of the oil casing is the passage of oil and gas to the ground, which isolates the oil and gas from the entire formation to ensure that the oil and gas pressure does not leak. After the oil and gas wells are transferred into production, the quality of the oil casings must be guaranteed to maintain a certain number of years of exploitation.
    Casing design for each size is done by calculating the worst conditions that may be faced during drilling and production. Mechanical properties of designed pipes such as collapse resistance, burst pressure, and axial tensile strength must be sufficient for the worst conditions.
