蒸汽压力管道安装焊接技术

Installation and Wielding Techniques of Steam Pressure Pipes

文章结合工程的实际情况,主要介绍主蒸汽管、再热热段焊接工艺要点及焊接质量控制。蒸汽管道属压力管道,其温度和压力都比较高,对焊接要求较高。合理的焊接工艺是控制焊接质量的重要手段。

Based on the engineering actuality, the paper introduces the technical key points of main steam pressure pipes and re-heated wielding and the controlling measures of wielding quality. Steam pipe refers to pressure pipe, whose temperature and pressure are high. It has higher requirements for wielding technique. In this case, reasonable wielding technique is an important means to control wielding quality.
