Twister used in an air extraction pump
Benefit: Cost Saving
Main Forming Process: Additive Manufacturing

Description

Twister component used in an air extraction pump of a combined cycle gas turbine plant condenser to create a swirl in the water flow. After an internal qualification program, the twister was successfully put into service in October 2016 and removed after 2000 hours in operation. Non-destructive evaluation did not reveal any cracking or critical degradation.

Benefits

  • Shorter leadtime and cheaper than conventional
  • Suitable for on-demand manufacturing of spare or obsolete parts, with comparable costs vs. 5-axis CNC machining
