20、单位审批施工方案后实施；4、减温减压器入口管道碰头，由于减温器地入口参数为高温高压，各施工器具应准备齐全，尤其是热处理设备，在焊接前可进行焊接工艺评定，符合后编制焊接工艺卡，经批准后实施；5、可以根据工期要求投入人力、物力，保质、保量保工期完成任务.管材到现场后及时进行防腐施工，现场预制部份管材暂不做防腐，预制完成后补做.节点处工作面必须足够大保证施工需要.6、热控与电气部分地施工在减温减压器施工结束后进行，各基础、设备支架应符合标准规定，取源部件与主体同时施工，包括防腐及保温，在试压时做好相应部件地保护工作.工程组经营组物资供应组办公室财务组质量检验组安全保卫组工程经理部各专业操作班组文档编
