Face to Face meeting
Liverpool June 2012
Cooling update task 2
Production of Staves, Stavelets and other bits and bobs.
Pressure drop work
May revise some of the 1.6m long variants and just keep the 316L ones as this means we can make in house and join.
This saves is £500 per circuit in 316L and £1k per circuit in CP2 Ti.
Need to discuss effort recharge as this is a big job and need to understand scope for it to be done somewhere else funded by the project, or have quotes for this to be completed externally.
Schedule is desirable.
With RAL for testing (PD)
6 Now made and at RAL
VCR fittings to stalks due on 9th July
Run out of VCR fittings so due from Manchester on Friday 21st – join next week
VCR fittings to stalks due on 9th July + pressure test pieces
Due for delivery on 28th Aug.
Spent far too long on vac brazing solutions for stainless to Ti. Now look to be successful and repeatable.
Ready to switch back to finishing off the 2.275mm CP2 Ti weld testing.
PIPE Ltd loaning us a tube flaring tool to make the sleeve joint required for welding 125um wall CP2 Ti.
New low current output weld system developed and now in production. Testing production unit once new lab ready in July.
Investigating comparisons between welding systems arc gaps, profiles
New electrodes sourced and under test – drop arc voltage again
Relocating laboratory to new work area so we don’t have contamination from tube preparation in the Ti welds. Will have RPS approval of work area in August (hopefully).
