5、Common nonconformance points in gas cylinder production
— Manufacturing imperfections of cylinders:
a/Bulge: Visible swelling of the wall for cylinders
Reason: raw materials are unqualified, heat treatment is not done in the production process of gas cylinders, and the production factory jerks and produces unqualified products
b/Dent (flats):A depression in the wall which has neither penetrated nor removed metal with a depth greater than 1 % of the external cylinder diameter (see Figure A.1; see also excessive grinding or machining)
Cause: The raw materials are not qualified or the cylinder production process is not in accordance with the strict requirements of ISO9809 production standard and lax in the cylinder process flow
