本文结合高密度聚乙烯装置大型反应器受道路限制无法实现设备整体运输进场，只能根据道路限高情况采取基地分段预制、现场组对的实际，针对首次采用Q370R主体材质、施工现场情况复杂、制造难度大的特点，介绍了进场材料检验、预制分段方案、组对成型控制、分布板加工、焊接工艺参数确定、焊接过程管理、分段和局部热处理、水压试验等过程质量控制措施确保了设备制造质量满足设计及使用要求。“,”As the large-scale reactor equipment in high density polyethylene device is not impossible to transport approach integrally restricted by road, prefabricate and ifeld assemble according to road restriction is the only way, aiming to the characteristics of using Q370R as subject material for the ifrst time, complex construction site, high dififcult in manufacturing, this paper introduces the quality control for the process of material-in inspection, precast block scheme, assemble molding controlling, distribution board processing, welding process parameters determination, welding process management, segmentation and local heat treatment, hydraulic pressure test, which could make sure the satisfaction of equipment manufacturing quality for the design and use requirements.
