某施工单位承包的机电安装单项工程办理了中间交接手续,进入联动试运行阶段。建设单位未按合同约定,要求施工单位组织并实施联动试运行,由设计单位编制试运行方案。施工单位按要求进行了准备,试运行前进行检查并确认:

(1)已编制了试运行方案和操作规程。

(2)建立了试运行须知,参加试运行人员已熟知运行工艺和安全操作规程。工程及资源环境的其余条件均满足要求。

联动试运行过程中,一条热油合金钢管道多处焊口泄露,一台压缩机振动过大,试运行暂停。经检查和查阅施工资料,确认管道泄露是施工质量问题。压缩机安装检验合格后,由于运行介质不符合压缩机的要求,未进行单机试运行,经业主和施工单位现场技术总负责人批准留待后期运行。

问题处理完毕后,重新开始试运行并达到规定的要求。经分析、评定确认联动试运行合格。施工单位准备了“联动试运行合格证书”,证书内容包括:工程名称;装置、车间、工段或生产系统名称;试运行结果评定。附件包括:建设单位盖章、现场代表签字;设计单位盖章、现场单位签字;施工单位盖章、现场单位签字。

已办理中间交接的合金钢管道在联动试运行中发现的质量问题,应由谁承担责任?说明理由。
