Beschreibung
Zusammenfassung:	The present invention relates a steam methane reformer tube outlet assembly and a method of assembling or retrofitting same. More specifically, it relates to an exposed flanged tube outlet of a reformer designed to mitigate metal dusting corrosion, dew point condensation-related metal fatigue and cracking, and over-temperature induced metal failures such as hydrogen attack. 本发明涉及一种蒸汽甲烷重整器管出口组件及其组装或改装方法。更具体地，本发明涉及重整器的暴露的凸缘管出口，其被设计成减轻金属尘化腐蚀、露点冷凝相关的金属疲劳和开裂、以及过温引起的金属失效诸如氢蚀。
