D.1 前 言 D.1.1在本附录中关于在0℃以下操作的容器选材、设计和制造方面的建议,均以焊接协会(前称英国焊接研究协会)对碳钢和碳锰钢板所进行的一系列带缺口和焊缝的威尔斯宽板试验(WWP试验)的结果为基础提出的。这些建议,除考虑了其它已知的WWP试验数据外,还特别参照了1964年3月的英国焊接杂志(British Welding Journal)中“低于零度的受压设备用低碳钢”(Mild Steelfor pressure equipment at sub-zero temperature)这篇报告的结果,同时,也反映了英国、美国和西德现
D.1 Foreword D.1.1 The recommendations in this appendix for the material selection, design and manufacture of containers operating below 0 ° C are based on the recommendations made by the Welding Society (formerly British Society for Welding Research) on carbon and carbon-manganese steel plates Based on the results of a series of Welsh wide-plate tests with notches and welds (WWP test). These recommendations, with the exception of other known WWP test data, also refer particularly to the “Mild Steel for pressure in Sub-Zero Compression Equipment”, British Welding Journal, March 1964, equipment at sub-zero temperature) The results of this report, but also reflect the United Kingdom, the United States and West Germany are
