Calpine Energy Seat Replacement

case study

CUSTOMER:Calpine
‍LOCATION:Wilmington, DE, USA
‍MATERIAL:2.25 Chrome

challenge

The project involved a valve seat replacement on a 14” 2.25Cr isolation gate valve with a restricted internal diameter of 8.63”, creating tight access conditions for machining and welding operations.

The confined geometry limited the use of conventional methods and required a high-precision approach suited to small-diameter internal work.
