4、Common nonconformance points in gas cylinder production
— Manufacturing celebrities of cylinders:
a/Neck cracks:Appear as lines which run vertically down the thread and across the thread faces (not to be confused with tap marks = thread machining marks; see Figure A.6)
5、Gas cylinder corrosion resistance
The influence of various elements in steel on corrosion resistance is as follows:
Carbon: generally, the lower the carbon, the less oxygen corrosion.
Manganese: manganese content (0.4 ~ 1.5%) in the case of high sulfur content, there will be manganese sulfide, which has an effect on corrosion, but in the case of low sulfur content, manganese and iron form a solid solution, which has no effect on corrosion.
Phosphorus: phosphorus content under 0.04%, can improve the corrosion resistance of steel in the atmosphere, especially when steel contains steel, corrosion resistance is more significant.
Sulfur: In the presence of manganese sulfide, as iron sulfide, there is an element of local battery formation, but little effect in neutral solution.
Copper: gas cylinder steel with copper content below 0.5% is solid solution, its corrosion resistance is very good, together with phosphorus, the effect is better.
Chromium: Molybdenum and chromium coexist, strong oxidation resistance, high corrosion resistance.
