SPECIAL RECOMMENDATIONS |
||||||
|
·
Methyl alcohol should not be used in the pressure
testing of tanks since failure can occur due to stress-corrosion cracking. ·
Should have very low interstitial content (i.e.
oxygen, hydrogen, nitrogen) to avoid hydrogen embrittlement, etc. This is
particularly important when there is a need for welding or heat testing. |
