27. Refurbishment Before-After

28. Refurbishment Process in EVAS

29. Refurbishment De-Gasing & Valve Removing EX-ZONE Detection of liquid gas2 Gamma radiation sources which detect up to 400 gr gas left in the cylinders. Drain and gas recoveryEmptying bottles and recovering the gas-in the gas phase or liquid.The recovered gas is stored and re-used. No atmospheric emissions! Valve removing All valves removed are stored and inspected later according EN14912 standard or as per customer specs

30. Refurbishment Washing & Visual Inspection Visual Inspection Then cylinders are visually inspected and separated either for repairing or scraping, or conform ones, send to the finishing hall. Inspection is realized by qualified and trained personnel. Internal WashingEvery cylinder is internaly washed in automatic carousel

31. Refurbishment Washing & Visual Inspection Straighten of Foot-Ring and/or Collar Changing of Foot-ring or Valve Guard Separated Damaged Cylinder

32. Refurbishment De-Denting Blowing Damaged cylinders are de-dented by means of pressured air and heating of dent zone.

33. Refurbishment Heat Treatment (stress relieving) at 600-630 oC Hydrostatic Testing Shot Blasting

34. Refurbishment Finishing Zinc Coating • Recording • Retest date, • Manufacture date • Manufacturer’s name Painting

35. Refurbishment Finishing Inkjet Marking Printing all information regarding tare weight, test date and next retest date on the cylinders. It allows much more legibility and visibility of all essential information. Valve Fitting Leakage Test

36. Refurbishment Before-After

37. No Repairable Cylinders Bulge Depresed Bung Lamination Cut (which exceeds min. thickness) Depresed Shroud or Foot-ring
