摘要
采用碳当量来评价管线钢的焊接性是工程上沿用多年的方法。目前 ,随着API5L第 42版对有关碳当量公式新的界定 ,引起了对管线钢碳当量的新的认识和讨论。在有关文献阅读的基础上 ,简要评述了管线钢的碳当量公式的作用、形成和不同碳当量公式的适用范围。
It to adopt CE to appraise the weldability of pipeline steel is a method for project that follows many years.Through the new definition of CE formula stipulated in API 5L,42 edition now,it is brought the new understand and discussion to CE of pipeline steel.It reviews the function,formation of CE formula in pipeline steel and applies scope of different CE formula.
