Dear all
i have a question about procurment & preperation of material specification that related to construction of storage tank for cryogenic liquid gas according API620&BS7777.
the specified steel for this project is P355NL2,THAT according BS7777-PART2 the impact testing is carried out in -50-(delta T).(delta T is acquired according ANNEX A)
now manufacture of steel said that due to time consuming of producing (delta T),he tested in lower tempreture of -50.
for preperaing of order & material specification , what additional requirement or testing is given to ensure haz &base metal have adequete impact value?
regard advances.
