0Cr18Ni9不锈钢制低温绝热压力容器(内胆)埋弧焊工艺的试验

The Experiment & Research on the Low Temperature Performance of Inner Tank of Low Temperature Adiabatic Pressure Vessel

本文针对用于制造低温绝热压力容器内胆的10毫米以上0Cr18Ni9奥氏体不锈钢,采用埋弧焊工艺并保证其焊接接头的低温韧性方面进行试验研究,从而得到了符合标准要求的满意结果。

This article describes the experiment & research on low temperature toughness of weld joints which on the inner tank of low temperature adiabatic pressure vessel. The material of the inner tank is 0Cr18Ni9 stainless steel;its thickness is over 10mm. The welding technology of it is submerged-arc welding (SAW).
