  1. TurboCare Sp. z o.o.NDT TESTS May, 2007

  2. scope of tests On usual basis we perform: • Material tests • Strength tests • Visual examination • PT, HD, MT and UT tests • RT tests – in cooperation • We use highest quality materials from companies such as : MR Chemie Gmbh and TIEDE • We use highest quality machines made by companies such as: TIEDE, Krautkramer, Equotip and DEUTSCH

  3. material tests • Material tests; • All material tests are done on basis of proper EN standards; • In preparation of samples process we use abrasive papers and diamond pastes or aluminum oxide suspensions; • We use only materials from known companies (e.g. STRUERS); • Preparation of replicas consist in vacuum evaporating and grading of tested materials – we use aluminum, gold or coal; • Microstructure observation showed in replicas is done by ZEISS NEOPHOT 32`microscope. Photographic recording is done by CCD-Insight Spot digital camera interfaced with photo processing computer system; • If necessary, for microstructure (samples or replicas) observation we use – in cooperation with Wroclaw Technical University – scanning or emission electron microscopes.

  4. non destructive material tests • Negative of triafol replicas are made on live object, removed and fixed by adhesive tape on sample glass; • Sample replicas are prepare by gold, aluminum or coal for further tests;

  5. destructive material tests • Example samples after impact resistance tests; • Special system for strength tests in 700°C;

  6. endoscopy and visual examinations • Whole scope of endoscope and visual examinations are done with careful photographic and descriptive documentation; • Welch Allyn Videoprobe 2000 videoscope test –Ø9mm 3m probe; • Olympus endoscope –Ø9mm 1,5m probe; • Pipelines endoscopy with industrial television from pipes with Ø40mm diameter to 15m length;

  7. ultrasonic tests • Tests are done according to EN standards and SIEMENS specific instructions of elements (parts) and specific materials tests; • For tests we use Krautkramer and Starmans equipment;

  8. ultrasonic tests • Bearings tests; • Bolts tests; • Casings tests; • Journal and shaft tests; • Rivets and blades tests; • Welds tests;

  9. wall thickness measurements • We perform thickness measurements using modern ultrasonic equipment; • Wall thickness: • Casings; • Pipelines; • Heat exchangers surfaces; • Hard to reach elements and elements available only from one side;

  10. magnetic powder tests • Tests are performed according to EN standards and SIEMENS specific instructions of elements (parts) and specific materials tests; • For tests we use TIEDE and DEUTSCH equipment;

  11. magnetic powder tests • All found defects are carefully documented and finally shown in protocol, with exact localization and photography;

  12. magnetic powder tests • During testing of high importance elements we use high sensitivity agents and we perform observation in UV light;

  13. long blades tests • Magnetic powder test in white and UV light; • Blade root dye penetrant test; • Blade root and rivets ultrasonic test; • Blade hardness test;

  14. dye penetrant tests • All elements made from non ferromagnetic materials are tested with dye penetrant method – observation is performed as well in white light as in UV light;

  15. hardness tests • We perform all kinds of hardness tests of materials and machine elements; • Vicers method hardness test with ultrasonic hardness tester (in Vickers, Brinell or Rockwell scale); • Energy method hardness test with EQUOTIP-2 hardness tester (in Vickers, Brinell or Rockwell scale);

  16. defect analysis • Using our knowledge acquired during many years of experience we could indicate probable causes of defects, formed during production as well as during operation;

  17. certificates • Tests leading personnel has all required certificates; • Training scope meets requirements of EN473 standard

  18. NDT inspection reports TurboCare Use Standard Inspection Record Sheets to record and report inspection results and where required dual language reports are provided: Example 1: Bearing Babbit Bond UT Report

  19. NDT inspection reports TurboCare Use Standard Inspection Record Sheets to record and report inspection results and where required dual language reports are provided: Example 2: Cylinder Blade Shroud Inspection

  20. NDT inspection reports TurboCare Use Standard Inspection Record Sheets to record and report inspection results and where required dual language reports are provided: Example 3: LP Overhead Pipework Magnetic Particle Inspection

  21. qualified NDT engineers TurboCare NDT Personnel are experienced Turbine Service Engineers with technical qualifications up to MSc In an Engineering discipline. Every engineer has appropriate NDT certification:

  22. references • NDT test are performed during all works performed by TurboCare Sp. z o.o. in Poland as well as in most of works abroad; NDT EXPORT TO: AUSTRIA GERMANY HUNGARY SERBIA BULGARIA BOSNIA/HERZEGOWINA
