13/64" Orifice Choke Bean – 410 Stainless Steel with Fully Lined Tungsten Carbide

The 13/64" Orifice Choke Bean is a premium, high-precision flow control insert engineered for use in positive (fixed) choke valves across demanding oilfield applications. Specifically built to manage continuous fluid pressure drops and maintain exact, unalterable flow rates, this choke bean features a robust 410 Stainless Steel carrier body paired with a fully lined premium Tungsten Carbide (TC) insert to withstand the industry's most abrasive and erosive flow regimes.

In positive choke manifolds, well fluids are subjected to immense velocity surges and severe localized turbulence as they pass through the choke bean's restrictive orifice. When dealing with frac sand, proppants, or high-velocity well-testing returns, standard steel beans can quickly erode or "wash out," altering the orifice size and compromising well control. To eliminate this issue, this bean's entire internal flow path is fully lined with solid tungsten carbide—one of the hardest compounds available. This provides an impenetrable defense against severe abrasive erosion, extending the trim life exponentially.

The outer sleeve is machined from high-strength 410 Stainless Steel, which delivers excellent mechanical structural integrity, high impact resistance, and dependable performance in standard to mid-corrosive oil and gas production environments.

Features & Benefits

• Fully Lined Tungsten Carbide: The internal bore is completely lined with solid tungsten carbide, delivering unparalleled resistance to severe sand erosion and high-velocity fluid wear.

• 410 Stainless Steel Carrier Body: The high-alloy steel outer body provides excellent structural strength, prevents mechanical cracking, and protects the inner carbide liner from high-impact damage.

• Precision Orifice Sizing: Machined to an exact 13/64" (Size 13) fixed opening to ensure a perfectly constant, repeatable, and tamper-proof production flow rate.

• Extended Operational Lifespan: Minimizes non-productive time (NPT) and choke maintenance costs by drastically reducing the frequency of bean replacement in high-sand flowback wells.

• Industry Compatibility: Engineered to standard dimensions for flawless compatibility and easy field installation within most major positive choke valve configurations.

Specifications & Technical Details

Applications

This fully lined tungsten carbide choke bean is a critical component for high-pressure surface flow control systems where fluid regulation must remain fixed and uninterrupted. It is highly recommended for aggressive frac-flowback operations, high-rate surface well testing packages, clean-up operations, and long-term production manifolds processing abrasive, sand-laden wellbore fluids.

Quality Assurance

All our tungsten carbide-lined choke beans are manufactured under strict quality monitoring systems to ensure precise geometric tolerances. The concentricity of the internal bore and the bonding integrity between the 410 SS outer body and the tungsten carbide liner are rigorously verified. Each bean undergoes detailed sizing inspections prior to shipment to ensure reliable performance under extreme field conditions.
