上104钢(12A1MoV)是上钢三厂,按照国内资源,创造出的低合金新钢种。五年多来,经过炼油厂高温硫腐蚀部位的挂片、单体设备和零部件的试验证明,这种钢具有较好的耐高温硫腐蚀性能。 山东胜利炼油厂,为适应含硫原油所占比例的提高,决定采用上104钢制造减压塔塔体及全部内件。为了更好地掌握上104钢的焊接工艺,由山东胜利炼油厂、山东化建
On the 104 steel (12A1MoV) is the steel plant, in accordance with domestic resources, to create a new low-alloy steel. Over the past five years, after the refinery high temperature sulfur corrosion parts hangings, single equipment and parts of the test proved that this steel has good high temperature sulfur corrosion resistance. Shandong Shengli Refinery, to meet the increase in the proportion of sulfur-containing crude oil, the decision to adopt on the 104 steel vacuum tower tower body and all the pieces. In order to better grasp the 104 steel welding process, from Shandong Shengli Refinery, Shandong Chemical Construction
