摘要
针对低温(-70℃)乙烯球罐09MnNiDR钢板和09MnNiD锻件的焊接,进行焊接工艺评定,由此制定了低温乙烯球罐的焊接工艺规范,并成功完成了低温乙烯球罐的制造厂内组焊制造及现场安装。
Aimed at the welding of low temperature（ -70℃ ）ethylene spherical tank 09MnNiDR plate and 09MnNiD forging, welding procedure qualification was made in this paper, thus the low-temperature welding process specification of the ethylene spherical tank was formulated, and finally to successfully complete the low-temperature ethylene spherical tank factory in compound manufacture and the site installation
