Precision steel cast parts are used in many oil drilling platforms. The investment casting design features and versatile material choice makes the steel cast part ideal choice to consider the safe, efficient, and long-lasting for the platforms.
Kindly check the key details about where they are used.
Precision steel cast parts are key components in equipment like centrifugal pumps and mud pumps. Take the 19123 pump casing bought by National Oilwell Varco (NOV) for example. We make it from gray cast iron using the investment casting method, and it achieves a precision level of CT4-6—way better than the CT10-13 you get with sand casting.
This pump casing meets the tough API 610 standards, handling a flow rate of 2600 cubic meters per hour, a head of 250 meters, and a pressure of 7.5 MPa. What’s more, these cast parts can stand up to the high-pressure impact of fluids and stay stable even in extreme temperatures—from as low as -80°C to as high as 450°C.
In high-pressure wellhead equipment, blowout preventers (BOPs) and choke manifolds use the precision steel cast components. For instance, CF8M stainless steel castings, with their corrosion resistance (resistant to Cl⁻ erosion) and high strength (yield strength ≥250 MPa), are widely applied in drilling tools and manifolds, reducing maintenance frequency by over 30%. Nickel-based alloys like Inconel 625 are used in high-temperature (above 450°C) and high-pressure (15000 psi) environments, demonstrating significantly better creep resistance than traditional carbon steel.
Safety components such as elevator plugs need to bear loads exceeding 100 tons. Traditional forging processes are costly and have long lead times. Vallourec uses Wire Arc Additive Manufacturing (WAAM) technology to produce elevator plugs that pass API 5C5 standard tests, meeting performance requirements under tension (500 tons), internal pressure (1,000 bar), and high temperature (200°C). This reduces manufacturing costs by 40% and shortens delivery time by 2/3.
