    Forging Internal Crack Analysis of Large Thick-walled Tube

    • On the inner wall surface through the cracks of large thick-walled tube for chemical composition analysis,hardness,mechanical testing,metallography inspection and analysis. The results showed that,inside large tube radial cracks due to the lack of time and forging heating-anvil approach improper use caused by forging the split.
