Custom Pipe Spools
with Flow Conditioning Vanes

Lake Michie Dam – Durham, NC

This project case study highlights a crucial component for the Lake Michie Dam Project: Flow Conditioning Cross and Flow Conditioning Tee, both equipped with custom-installed flow straightening vanes. These specialized parts are integral in improving the efficiency and functionality of water management systems at the dam. The Flow Conditioning Cross and Tee with custom vanes are meticulously designed to refine the flow dynamics, meeting and exceeding industry standards for water flow management. By strategically straightening and conditioning the water flow, these innovations significantly reduce turbulence and streamline the water passage. This advanced approach is pivotal in boosting the overall performance and reliability of the Lake Michie Dam’s water control infrastructure, ensuring optimal operation and management of water resources.

Project Overview

Purpose and Benefits of the Flow Optimizer Vaned Tee

Flow Conditioning Vaned Tee Inserts are engineered for installation in piping systems before a Pump, Valve, Heat Exchanger, Orifice Plate, or Flow Meter. These inserts, when paired with suitable minimum pipe lengths, assist in minimizing flow disruptions caused by upstream pipe layouts or valves.

The 48 inch Tee with custom installed flow straightening vanes is a critical component in the water purification process. Its primary function is to enhance the pump’s efficiency and longevity. Here are the features and benefits:

  • Eliminates surface and sub-surface vortices
  • Ensures smoother pump operation
  • Reduces vibration, thereby extending pump life
  • Lowers noise levels for quieter pump operation
  • Decreases water turbidity, enhancing water quality

Purpose and Benefits of the Flow Optimizer Vaned Cross

Flow Conditioning Vaned Cross or Grid Inserts are used when upstream piping is less than ideal, and not per Hydraulic Institute guidelines. Typically flow straighteners are used after an Elbow, Tee, or when there are reduced pipe lengths. Our spools are mounted directly in front of a flow meter (air) or pump suction (liquid) where a swirl, pulsation, or flow separation exists.

Our grid will create a slight flow restriction which helps to stabilize and/or re-direct the flow to be more like a theoretical flow profile.
NOTE: Hydraulic Institute recommends a grid length “L” = 1xD to 3xD (D = diameter of the pipe)

The 48 inch Cross with custom installed flow straightening vanes is designed to separate and straighten the flow and typically mounted upstream of the pump.

  • Eliminates surface and sub-surface vortices
  • Ensures smoother pump operation
  • Reduces vibration, thereby extending pump life
  • Lowers noise levels for quieter pump operation
  • Decreases water turbidity, enhancing water quality

Conclusion

The installation of the 48 inch Flow Conditioning Cross and Flow Conditioning Tee, both equipped with custom-installed flow straightening vanes, at the Lakie Michie Dam represents a significant improvement by addressing a wide range of hydraulic challenges. These components not only enhance the efficiency and effectiveness of the pumping system but also contribute to the overall reliability and sustainability of the dam. The collaboration between Hazen and Sawyer, Clemson Engineering Hydraulics and Crowder Construction in this project highlights the importance of expert engineering and construction practices in achieving the project’s goals.
