  • Textured surface of oil and gas equipment and machining method thereof
    Patent number: 12390884
    Abstract: A textured surface of oil and gas equipment includes a first substrate, an antiwear coating, and a second substrate, and further includes a texture, where the texture includes a first texture and/or a second texture; the first substrate and the second substrate are capable of moving relative to each other when operating, the first texture is arranged on a surface of the first substrate that is in contact with the antiwear coating, the second texture is arranged on a surface of the antiwear coating that is in contact with the second substrate. A method for machining the textured surface of oil and gas equipment is provided, which improves various performances of the oil and gas equipment such as antifriction, wear resistance, and corrosion resistance by combining a coating with a texture, so as to prolong the service life of the oil and gas equipment, increase oil and gas production efficiency.
