The manufacture of large size low temperature ethylene spherical tank is a key technical problem tackling project equipment in Chinas “Eighth Five year Plan”period.
选择４４ｍｍ厚ＣＦ－６２钢板、０８ＭｎＮｉＣｒＭｏＶＤ锻件和Ｊ６０７ＲＨ焊条为１５００ｍ３乙烯球罐的主体用材。
The main technology of manufacturing the-45～-50 ℃ 2000 m3 ethylene spherical tank have been cleared.
通过-50℃低温钢15MnNiNbDR钢板以及配套锻件、配套焊接材料的应用研究,掌握乙烯装置用-45~-50℃的2000 m3乙烯球罐的制造关键技术;通过对制造过程中各关键环节的严格控制,研制出容积2000 m3、设计温度-45℃、设计压力1。
However, the existence of welding residual stresses seriously threatens an ethylene spherical tank’s service life and even might result in severe security disaster; therefore it is imminent to solve this problem.
