摘要
近年来 ,我国从美国、日本引进的一种新型马氏体耐热钢SA335 -P91,用于大中型、高参数电站主蒸汽管、再热蒸汽管热段和锅炉末级过热器出口联箱等重要部件。本文介绍了珠海发电厂 2× 660MW机组安装工程中SA335 -P91钢材的焊接经验。
Recently, a new type of martensitic heat-resistant steel,SA335-P91 has been introduced into our country from America and Japan .It is used in the important parts of the large and medium utility and high parameter power station ,such as the main steam piping ,the reheat steam piping (hot spool),the outlet header of the final super - heater of boiler, etc. In this article, the welding experience of this steel in Zhuhai power station 2×660 MW units erection project is presentated.
