4、 Common nonconformance points in gas cylinder production
— Manufacturing celebrities of cylinders:
a/Groove:A longitudinal notch having a depth of 3% or more than wall thickness (see Figure A.4)
⎯ Inside imperfection: when depth exceeds 5 % of wall thickness or when length exceeds 10 % of the length of the cylinders
⎯ Outside imperfection: when depth exceeds 5 % of wall thickness or when the length exceeds 5 times the thickness of the cylinders
5、Thread handedness ofcylinders:
The thread shall be a right-hand thread, such that it moves away from an observer when rotated clockwise.
