4、 Common nonconformance points in gas cylinder production

-- Manufacturing celebrities of cylinders:

a/Shoulder folds and/or shoulder cracks :Folding with peaks and troughs situated in the internal shoulder area, which can propagate into the threaded area of the shoulder (see Figure A.7)

⎯ Folds or cracks which are visible as a line of oxide running into the threaded portion shall be removed by a machining operation until the lines of oxide are no longer visible (see Figure A.7) After machining, the whole area shall be re-inspected carefully and the wall thickness verified

5、b/Cracks can start from folds in the internal shoulder area and propagate into the cylindrical machined or threaded area of the shoulder (see Figure A.8 for exactly where shoulder cracks start and how they propagate)

⎯ If folding or lines of oxide have not been removed by machining, if cracks are always visible or if wall thickness is unsatisfactory

⎯ Folds which extend beyond the machined area and are clearly visible as open depressions where no oxides have been trapped into the metal, shall be accepted provided that the peaks are smooth and the root of the depression is rounded
