5、概况中粮生物化学（安徽）股份有限公司（燃料乙醇）项目共有三十台储罐，依据相关规范及标准，对罐体进行无损检测工作。1.2编制依据及验收规范1.2.1GB50128-2005《立式圆筒形钢制焊接储罐施工及验收规范》；1.2.2NB/T47013.1～6-2015《承压设备无损检测》；201.2.3GB50341-2014《立式圆筒型钢制焊接油罐设计规范》；1.2.4SH/T3167-2012《钢制焊接低压储罐》；1.2.5NB/T47015-2011《压力容器焊接规程》；1.2.6HG/T20569-2013《机

6、械搅拌设备》；1.2.7计图纸文件要求的其他规范、规程；1.2.8GB18871-2005《射线卫生防护基本标准》。1.3检测工作要求1.3.1发酵区储罐探伤要求：底及次圈罐壁纵焊缝100％射线探伤，Ⅲ级合格；底及次圈罐壁环焊缝和其余各圈纵焊缝20％射线探伤，Ⅲ级合格；其余各圈环焊缝2％探伤，Ⅱ级合格；罐壁所有丁字焊缝100％射线探伤，Ⅱ级合格；底圈壁板与罐底内外角焊缝100％磁粉探伤，Ⅰ级合格；罐底边缘板（外缘300mm）对接焊缝100％射线探伤，Ⅱ级合格；罐底板T型焊缝根部和表面100％磁粉探伤。1.3.

7、2乙醇成品罐区及乙醇中间罐区储罐探伤要求：按GB50341-2014中的第12.2条及GB50128-2014中的第7.2条相关条款规定进行探伤。一、主要检测项目的保证措施2.1概述1无损检测指令由本工程的无损检测业主工程师下达；2无损检测依据《承压设备无损检测》(NB/T47013.1~47013.6-2015)为此，我公司制定了以下检测方案：射线检测采用以X射线探伤机检测法为主，对不适合射线检测的部位采用超声检测；对于表面及近表面缺陷的检测：铁磁性的材料采用磁粉检测；非铁磁性的材料采用渗透检测。针对既定无

8、损检测方案，我公司对人员、设备、材料、工艺、设施等各个方面进行了周密的安排，并在本施工组织设计中编制了详细的措施。2.2射线检测方案1.总则1.1适用范围：本规程适用中粮生物化学（安徽）股份有限公司（燃料乙醇）项目。1.2依据：GB5O128-2005《立式圆筒形钢制焊接储罐施工及验收规范》NB/T47013.2-2015《承压设备无损检测》1.3检测人员：必须由取得锅炉压力容器无损检测人员资格考核
