Tungsten Carbide Choke Bean

Engineered for High-Pressure Flow Control in Harsh Oilfield Environments. Retop’s tungsten carbide choke beans deliver outstanding wear resistance and flow control stability under abrasive, high-pressure, and corrosive fluid conditions — optimized for extended service life in severe service choke valves.

Product Description

Tungsten carbide choke beans are precision flow control components used in positive and adjustable choke valves to manage wellhead pressure and flow rate in upstream oil and gas operations. Made from cemented carbide, these choke beans feature superior hardness, erosion resistance, and dimensional stability, making them ideal for handling aggressive fluids like sand-laden gas, acidic brine, and mud slurry.

These components are widely used in drilling manifolds, production trees, fracturing equipment, and mud circulating systems. Common application scenarios include offshore platforms, shale oil completions, gas reinjection wells, and onshore production facilities. Their high durability makes them indispensable in critical flow management.
