The problem of solving be also and its numerous and diverse；Specifically, temperature gas cooled reactor steam generator steam (vapor) outlet connecting pipe structure is just
It is one of them and its crucial research project, current China is to temperature gas cooled reactor steam generator steam (vapor) outlet connecting pipe structure
There is more in-depth study, and obtained more great achievement in research, also the achievement has been done in the prior art
Certain record；
Such as Chinese patent, Application No. 201020655609.X, it is entitled " temperature gas cooled reactor steam generator connecting pipe
Attachment structure ", Application No. 201610390319.9, entitled " temperature gas cooled reactor steam generator steam (vapor) outlet connecting tube list
Root poling attachment structure ", Application No. 201610392844.4, entitled " temperature gas cooled reactor steam generator feedwater connecting tube
Temperature gas cooled reactor steam generator steam (vapor) outlet connecting pipe structure is disclosed in the patent documents such as single poling attachment structure ", by
