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.
