乙苯烷基化反应器开孔改造的焊接工艺评定

WELDING PROCEDURE QUALIFICATION OF OPENING RECONSTRUCTION FOR ETHYLBENZENE ALKYLATION REACTOR

结合乙苯烷基化反应器改造工作，介绍了Ｃｒ－Ｍｏ钢（含Ｃｒ５Ｍｏ＋Ｃｒ５Ｍｏ，１５ＣｒＭｏＲ＋Ｃｒ５Ｍｏ）焊接中采用同质焊接材料时的焊接工艺、焊接材料的选择和焊后热处理制度。

In combination with the reconstruction of ethylbenzene alkylation reactor,the welding procedure,selection of welding material and post heat treatment of CrMo steel (includ Cr5Mo+Cr5Mo,15CrMo+Cr5Mo) with similar welding material are recommended.
