1. Flexible lines production and planning
Claudio Bortolin (PH-UAT)
Jan Godlewski (PH-DT)
Bart Verlaat (Nikhef)
Sven Vogt (MPI)
Review of the IBL detector to cooling system interface - 11 March 2014

2. The program Optimize the design of the components (Sven’s talk) ✔
Purchase the components: flex hoses, Swagelok fittings, vacuum parts ✔
Contact the welders and the mechanical technicians for the production ✔
Purchase the orbital welding heads ✔
Pre-agreement with EN-MME for X-Rays checks schedule and availability ✔
Delivery of the purchased components: partially delivered
Flex line parts production and assembly: work in progress
Orbital welding and X-Rays: between week 12 to 15
Flex lines leak tests: week 15 and 16

3. General schedule

4. Week 10-11 MLI insulation: done (G. Glonti and P. Gach)
Flex hoses (11 m): delivered
Orbital welding heads: partially delivered
Brazing test: several testes carried out to optimize the design. Still waiting for metallography check
Brazing made by: Agostino Vacca (EN-MME)

11. Orbital welding program
We have to carry out 28 OW 4mm, 28 OW 17.2mm, 14 OW 14mm, 14 OW ¼”,
42 OW 3mm.
Week 12: 14 OW 4mm and X-Rays + 28 OW 17.2mm
Week 13: 14 OW 4mm and X-rays + 14 OW 14mm
Week 14: 14 OW ¼” +X-Rays + part of the OW 3mm
Week 15: rest of OW 3mm + X-rays

12. Manufacturing of the parts
Rotatable connector: machining of the pieces being carried out at MPI (delivery at CERN from this week); the first prototype leak and pressure tests were successful
Dynamometric wrench: 25 Nm to seal
the connection (Swagelok specification)
¼”Gasket
Nut
Sealing glands

13. Leak test
Helium leak test: we will pressurize the liquid and gas pipes and check any leak with the vacuum hoses connected to a leak detector
Cap
Helium Bottle
at Cristal palace
Helium leak detector

14. Summary Material ordered: partly delivered to CERN
MLI insulation concluded
The Swagelok components are being machined: first delivery to CERN this week
Orbital welding program has been defined: very tight schedule starting from next week. Welding heads being delivered, still waiting for the smaller ones
Brazing joint design optimization and test done last week: still waiting for metallography check
Leak test will take place before moving the flex lines to SR1
