摘要
论述了氢环境服役厚壁压力容器用高温耐蠕变钢2.25Cr1Mo0.25V的焊接。目前已有许多规范和标准阐述了这类钢的焊接,如美国石油协会实用推荐934—A《高温高压氢服役铬钼钢及铬钼钒钢材料及使用》。提出了埋弧焊条件下这类钢的焊接要点,以确保在特定服役条件下,焊缝达到的技术要求。
The welding of high temperature creep resistant of 2.25Cr1Mo0.25 V steels for heavy wall pressure vessel for hydrogen service was introduced.Welding of these steel grades is widely covered by standards and codes,especially by API Recommended Practice 934- A.The aim of this paper is to provide the additional recommendations,applicable to submerged arc welding,to ensure sound welds and satisfactory service properties of welded joints.
