摘　　要：简要介绍了统计过程控制(简称SPC)的概念,分析了在制管质量控制中应用SPC的必要性。以埋弧焊接工序关键质量特性———焊缝内在质量的控制为例,阐述了螺旋埋弧焊管质量控制实施SPC的一般步骤和方法。借鉴国内部分企业实施SPC的成功经验,提出了制管企业质量管理中应用SPC应注意的问题。The article introduces the concept of statistics process control,and states the necessary of SPC application into quality control of steel pipe manufacturing.It also raises examples as internal quality control on weld——main quality characteristic of arc weld process,and states general methods and process of SPC application.Meanwhile it also raises noted measurements on SPC application in steel pipe manufacturing based on the successful experience of SPC application in national enterprises.

关 键 词：统计过程控制(SPC) 焊管企业 质量管理
