  6. P&ID for IT-4189 IT-4189: Drawing 2

  7. Preliminary configuration study TL1 IT-4189: Drawing 1 • sub-assemblies of TL1 and room temperature piping shall not exceed: 1.9 m × 2.2 m × 12 m (width × height × length); • TL1: 3x DN20 + 1x DN40 process pipes + shield; • No bellows on cryogenic process pipes; • Thermal contraction taken by flexible hoses located in one point; • Vacuum barriers preferably in transfer line. thermal compensation boxes

  8. Preliminary configuration study VB1 IT-4189: Drawing 5 • 3 cryogenic valves, thermal shield, 2 cryogenic interfaces; • Phase separator + heat exchanger, heater and instrumentation; • safety valves, PTs, TTs • 5 kW electrical heater; • Maximum diameter: 1200 mm; • Maximum height incl. valves: 2050 mm; • Purge panel: 200 × 1000 mm; • Supports as indicated. • Exact position of interfaces will be provided after contract award.

  9. Preliminary configuration study VB2 IT-4189: Drawing 6 • 7 cryogenic valves, thermal shield, 3 cryogenic interfaces; • Phase separator, heater, instrumentation; • Safety valves, PTs, TTs; • Maximum diameter: 1200 mm; • Maximum height incl. valves: 2150 mm; • Maximum height for dismounting valves: 2985 mm; • Instrumentation panel: 200 × 1000 mm; • Exact position of interfaces will be provided after contract award.

  10. Installation at the CERN site CERN will provide: • Helium, argon and nitrogen required for installation at CERN; • Transport and handling of the supply on the CERN site; • Site services such as electricity and compressed air required for installation at CERN; • Space for a barrack at the surface for storage of materials and tooling; • Scaffolding (not for hoisting purposes); The contractor shall provide: • All tools and materials required for the proper execution of the contract; • Hoisting equipment for installation of the transfer line; • The vacuum pumps and leak detectors required for pressure and leak testing; • X-rays (100% on cryogenic process pipes!); • All personal protective equipment for its personnel (i.e. helmets, goggles, shoes, self-rescue masks) The contractor shall reserve two working days for the required training and access formalities of its personnel at CERN.
