HG-1900/25.4-YM4型锅炉安装焊接方案

Installation welding project of HG-1900/25.4-YM4 boiler

焊接是锅炉安装中的一道重要工序,合理的焊接施工方案能够降低焊接难度,减轻工人劳动强度,提高焊接质量。详细分析了HG-1900/25.4-YM4型锅炉安装施工中省煤器、水冷壁、再热器、过热器、P91大径管焊接施工方案,指出安装中需注意的问题,为同类型锅炉的焊接施工组织及实施提供了借鉴。

Welding is an important process in installation of boiler;a reasonable welding construction project can reduce the difficulty of welding and working intensity for workers,and improve the quality of welding.This paper sums up the installation experience of HG- 1900/25.4-YM4 boiler,expounds the welding projects of economizer,reheater, superheater and P91 large diameter pipe,points out the problems shonld be paid attention to in installation,and supplies the organization and implementation of welding construction for tile same type of boiler with some experience can be used.
