Dear all,
i am challenged by my manufacturer of boiler that as long as impact test performed for the material of shell, why still mandate drop-weight test.
BTW,the drum of boiler is constructed of low alloy steel with about 90mm thickness.
so i don't know how to answer the question but just say that the code mandates that.
i'd like to know what is the inherent difference between the two test, while both cares about toughness of steel?
Thanks so much
Jay
