Taiwan to Use Phoenix Inpsection Systems Scanner for Steam Turbines
Posted: 2012-12-19
Taipower, the Taiwan power company, has taken delivery of a new ultrasonic
inspection system for testing steam turbine bores from Phoenix Inspection
Systems, the UK nondestructive testing (NDT) equipment specialist.
Phoenix has supplied a boresonic scanner based on its popular TSIS (Turbine
Shaft Inspection System) model, which is used by leading operators in plants
throughout the world.
Phoenix worked closely on the project with the Canadian company Zetec, which
supplied the control and acquisition systems. The system will be used for
testing rotor bores within Taiwan power plants and also for repairs in the
workshop.
Turbines are subject to major stress and rotor shafts require regular inspection
to check for corrosion or fatigue. Testing is also an active way to extend the life
of plants and improve cost-effectiveness. The TSIS fully automated system can
test turbine shafts ranging from 70mm to 300mm in diameter and up to 14m
long in only one shift. This latest version incorporated a support and leveling
table to improve the set-up time.
Bryan Forth, project manager with Phoenix, said: "TSIS set the standard for the
inspection of turbine shafts and it remains popular with clients around
theworld, as this latest order demonstrates. The design of the system facilitates
helical scanning and allows the head to rotate continuously without damaging
any cables. It also means ultrasound and eddy current scans can be carried out
simultaneously, which saves doing two separate inspections."
