The low-pressure blades of steam turbine work in wet steam, and the blades produce water erosion under the action of water droplets. In particular, the low-pressure last stage blade is vulnerable to water erosion due to high steam humidity and high circumferential speed

Solution:

Wuxi Kaifei integral structure (non welded) hollow stationary blade adopts high-quality precision casting blank combined with NC machining profile, which is incomparable for hollow stationary blade with steel plate welded structure. The successful delivery of 72 inch hollow stationary blades of Kaifei saved the critical situation that there was no place to purchase the last stage stationary blades of cap1400 National Nuclear demonstration project at home and abroad
