  1. IBL - LAPP Cooling lines Design and production status and schedule Installation LAPP team Jacky Ballansat, Jean-Philippe Baud, Patrick Baudin, Pierre-Yves David, Pierre Delebecque, Sabine Elles, Nicolas Massol, Thibaut Rambure, Theodore Todorov, TamerYildizkaya

  2. Design and production status

  3. Design and production status • Stainless steel cooling lines production • 14 A sidelines 95% ready (last adjustments on the template (deliveredW16), final bending in the Splitter box region and ends lenghadjustments to bedone) • 14 C sidelines to bebent(W16)

  4. Design and production status • Isolators • 28 elementstested / 26 validated (all at room temperature 150 bars He and 3 at cold) – 10 % failed

  5. Design and production status • Splitter boxes A and C sides • Design almostfinished (delay due to changes askedafter the review / isolations) • Delivery of the final modelsplannedW17 • Temporary plastic model willbeproduced for adjustments and welding phases (W16)

  6. Design and production status • Welding stands • 2 tables A and C sides to bedelivered and mountedW16-W17 • Inlet/outlet connexion (metalic version) deliveredW18 – Plastic version shouldbeavailableW16-W17 for adjustments

  7. Design and production status • Transportation toolings • 2 toolings A and C sides to bedelivered and mountedW16-W17

  8. Fitting protection and repair scenarii • 1- Protection of the fittings an reability • All the fittings have a cap protection • Beforeanyassembly and tightening the cone and the sphereiscleanedwith alcool and a visual inspection isdone • The more critical part is the sphere, located on a dismountable part (outside) • Hundredsmounting/dismounting have been performedwithoutany issue (LAPP and SR1) • All the fittingpassed the leak tests withsignalslessthat 10-8 mbar.l.s-1 @ 20 bars He (specis 10-5 mbar.l.s-1 @1 bar) • Whenwe first try to damage the fitting for the repair test the leaklevelwastoolow (10-7 mbar.l.s-1) so the technicianhad to scratch the surfaces once again.

  9. Fitting protection and repair scenarii • 2- Repair scenarii • First step In case of issue : the torque canbeincreased up to 6 N.m • Second step : put some glue between the sphere and the cone. The samplespassed the leak tests before irradiation but not after : conditions of the irradiation to beclarified. • Thirdpossibility : using a specialmetalicpieceused a asealbetween the sphere and the cone (C.F Eric) Gluingtool

  10. Installation

  11. Installation – Transportation and assembly • Need a time slot (half a day) to check the transportation and flexible line deployment
