API 6A / 16C Heavy-Duty Hydraulic Fracturing Distribution Manifold and Erosion-Resistant System

  • Continuous high-volume hydraulic fracturing carries intense sand volumes that rapidly wash out standard flowline crossovers.
  • Built with targeted thick tungsten carbide erosion barriers to streamline extreme fluid velocities and safeguard downstream pipe networks.
  • Tailored for high-stage shale gas developments, heavy-sand hydraulic fracturing, and continuous post-frac well cleanups.

Main Advantage & Solution

  • Extreme friction and wash-outs caused by heavy-sand volume fracturing backflow.
    Solution: Engineered proprietary 175MPa heavy frac manifolds. Outfitted with dynamic anti-erosion flow-crossover subs embedded with high-density tungsten carbide inserts to streamline fluid physics and trap turbulences.
  • Complex rigging and massive weights of multiple surface lines.
    Solution: Optimized modular layout options (single-wing, dual-wing, multi-wing) with high-strength hammer unions for rapid, safe field setup.

Application Scenarios

  • Unconventional Hydraulic Fracturing: Designed for high-volume, multi-stage frac jobs in shale gas and tight oil reservoirs.
  • Multi-Well Zipper Frac Operations: Modular manifold setup for continuous fluid distribution across multiple adjacent wellheads.
  • High-Pressure Acidizing & Stimulation: High-alloy corrosion/erosion-resistant fluid paths for matrix acidizing and large-scale well interventions.
