材料检验(本文系指工程采购中的管道材料的检验及设备质量控制过程中的材料检验)是工程采购中的一个重要环节,主要包括板材、法兰、外购封头、设备内换热管、设备外管道用钢管、各种管件、阀门、紧固件等的检验。从制造加工方法看,这些材料包括轧制品、锻制品、铸件、焊件等,其产品质量直接影响到设备质量和工程质量,是不容忽视的一个质量控制环节。
Material inspection (this refers to the project procurement pipe material testing and equipment quality control process of material testing) is an important part of the project procurement, including plates, flanges, purchased head, heat exchange tubes within the equipment , Outside the pipe equipment pipe, all kinds of pipe fittings, valves, fasteners and other testing. From the perspective of manufacturing and processing methods, these materials include rolled products, forged products, castings, weldments, etc. The quality of their products directly affects the quality of equipment and engineering quality, which can not be ignored as a quality control link.
