  1. TRT Leak Repair Anatoli Romaniouk, 22.05.2013

  2. EC leak tests Side C Side A

  3. Location of the pipes with leaks B3 OUT F 13 1155 mm Ch. 9 Leak 2 l/h EC Side C B5 OUT F 9 910 mm Ch. 11 Leak 0.3l/h A6 OUT F 20 1526 mm Ch. 6 Leak huge B3 Bracket А4 Bracket B5 Bracket А6 PPF1 connector A4 OUT F 24 1814 mm Ch. 4 Leak huge А3 Bracket A1 OUT F 1 2388 mm Ch. 1 Leak 17l/h A3 OUT F 26 1963 mm Ch. 3 Leak 0.3 l/h А1 PPF1 connector А2 Detector side A2 OUT F 28 2099 mm Ch. 2 Leak 0.3 l/h

  4. EC Side C: Endoscope studyPipes were cut and were studied with endoscope from inside

  5. A1 crack along the pipe (PPF1 connector)

  6. A4 PPF1 bracket.

  7. Detector connector

  8. This pipe should be repaired To go inside we need to open some accesses Repair should be done also here (PPF1 area)

  9. Example how pipes installed on the calorimeter flange

  10. EC wheel type A connectivity Electronics Electronics PEEK pipes shown in pink Gas OUT Gas IN Gas manifold Gas manifold Straws/radiator Straws/radiator Places of stress Gas Gas

  11. EC: on detector connection

  12. PEEK pipe termination Most probable location of leaks

  13. Repair at the detector level Most probable places of leaks Connector Nut PEEK pipe Steel pipe Insert Removable steel road Polyurethane joint

  14. Example how pipes installed on the calorimeter flange

  15. Repair status

  16. Next steps: • Today - try to go outside of the tube ( A4 and A6) and see what can be done at the place of connection. • End of the week - Close C side (if no additional repair can be made) and start working with side A. • When side A will be available to start preparatory work?
