Introduction
Testing Valves in Asia
Fifth Annual QUIKLOOK
Users Group Meeting
Stock options are overrated ….
China
– 12 Plants under construction
– All Westinghouse AP1000 (Advanced
Passive)
– 50% less safety related valves
– 80% less piping
– 85% less cable
– Haiyang Site 6 reactors
– Sanmen Site 6 reactors
– About 16,000 megawatts total
China
– Westinghouse did a technology
transfer to the Chinese for AP1000
– Signed contract with Westinghouse
– Cannot market the AP1000 outside of
China
– Scaled up the AP1000 to AP1400
– Marketing AP1400 outside of China
Conceptual View AP1000
Taiwan
– Lungmen Nuclear Power Plant
– GE ABWR (second built, first is in
Japan, biggest nuclear plant in the
world)
– 2 units 1350 megawatts each
– Fuel load planned for April 2012
(Unit 1)
– 9.2 Billion USD (may never start)
– 4 years behind schedule
ABWR Reactor
Lungmen/GE valve spec specified stem
mounted strain gages on all safety
related MOVs
– Lungmen plant has 400 safety related
valves
– 200 per unit
– No valve testing required prior to
shipping valves to Taiwan
Westinghouse spec for valves in China
included diagnostic testing prior to
shipment
– For MOV
– For AOV
– For BOP
The spec was tailored for stem mounted
strain gages
– QSS
– SMARTSTEM
China / Taiwan
– Waited to perform diagnostic testing
– Basically waited for US to do the research
– Then wanted testing done for ½ price
Taiwan
– Does lots of valve and actuator
maintenance
– Based on schedule
– Maintenance work quality is poor
– Use incorrect grease
– Don’t do many stem lubes
The first 4 units (2 at each of the China
sites) big valves were procured by US
valve companies
– Flowserve
– Velan
– Weir
The big contract went to Flowserve
– Gates
– Globes
– MSIV
The remaining new plants in China
– Most valve contracts went to in country
companies
• Shentong Valve (own Quiklook)
• Sufa
• Shenjiang Valve (will purchase)
– US companies bid but can’t compete
• Valves built in China are low quality
• Use cheap actuators
• They don’t understand weaklink
• Required thrust determination is not
standard
Roger and I hosted a seminar in China
last year and invited:
– Flowserve
– Automatic Valve
– Top Works
– Curtis Wright (EGS connectors)
Teledyne has signed up a China
Distributor
– Chance Development (H.K.) Limited
– They are pushing Quiklook/QSS in
China
– Company President is former Nuclear
employee
Velan
– Had Quiklook for a number of years
Flowserve
– Bought Quiklook in 2009
Weir
– Bought Quiklook in 2010
Taiwan Power
– Using Quiklook since 1994
China Valves (AP1000)
– All valve tested static and “DP”
before shipping
– 20 to 30 strokes required per valve
– Reduced and nominal voltage
– Actuator sizes are very conservative
– All SR MOVs are DC
– BOP all AC

(Flowserve)
36” MSIV Gate Valve
Taiwan Power Company
– Teledyne awarded contract for AOV
Program (Turn – Key)
• Design Basis Calculations
• Weaklink Analysis
• Static Testing
• Dynamic Testing
Used ACE 3.0
Used ACETest
Used Quiklook
AOV Scope
– 68 valves
– 68 static tests
– 6 dynamic tests
TPC I/C Staff
– Very limited valve experience
– Do not understand testing
– They kept asking me about torque
switch settings??
TPC is slowly adopting how we do
business
Just began using safety glasses/shoes
Use pre-job briefs
– Called TBM
– Tool Box Meeting
The TBM ….
First time TTS used Windows 7 for the
Quiklook operating system
XP software difficult to obtain
Future system will use Windows 7
Discovered weakness with I/P circuit
New board is in Engineering
Valve population included
– 9 Fisher actuators
– 25 Automax for quarter turn valves
– 34 Valtek
Valves were very high margin
Most valves have no regulators
Full air pressure
– Actuator nameplate indicated 100 psi
max
– Measured 120 psi
Valve Pics - Automax
Valtek (on-off)
Fisher – 3-Way Control Valve
MSIV in DW
Testing with QLII
