Cov khoom siv yog siv rau chav dej-dej ntawm boiler lossis chav turbine ntawm thermal power supercritical (ultra-supercritical) unit.
- Lub valve lub cev txais tag nrho cov qauv forged.
- Sealing hom ntawm lub cev lub cev thiab lub kaus mom txais lub siab tus kheej sealing qauv.
- Sealing nto ntawm lub rooj zaum valve muaj Stellite 6 alloy build-up welding.
- Sealing nto ntawm lub valve disc muaj Stellite 12 alloy build-up welding.
- Nrog curb (los yog annular siab txo groove) ntawm nws pem hauv ntej, lub sealing nto tuaj yeem tiv thaiv particle thiab impurity nyob rau hauv cov kav dej los ntawm crushing lub sealing nto thaum lub valve kaw.
- Lub sealing ib feem siv ob-kauj ruam throttle element siab txo cov qauv thiab nruab nrab siab txo cov kauj ruam los ntawm kev tiv thaiv cavitation thiab scouring los ntawm kev puas tsuaj rau lub sealing nto.
