醋酸工厂工程中锆材管道焊接关键技术

The key technology of zirconium alloy pipeline welding in acetic acid factory engineerin

锆材是在工业(特别在核工业、军事工业)中使用过的一种有色金属材料;锆(Zr)和钛(Ti)在元素周期表中同属于第Ⅳ类元素,都是很活泼的金属,对碳(C)、氧(O2)、氢(H2)、氮(N2)有很强的亲和力。锆(Zr)的焊接性能和钛(Ti)相近,目前实际民用工程应用较少。在此以醋酸工厂锆材管道焊接为素材,分析了锆材焊接热循环特性,介绍了锆材焊接中的具体技术要求和焊接要领,应用工厂和现场资料,阐述了锆材管道焊接关键技术,有较大的参考应用价值。

Zirconium is already in the industry （especially in the nuclear industry, military industry） used in a nonferrous metal material; Zirconium （Zr） and titanium （Ti） with belong to the first class IV elements in the periodic table, are very active metal, carbon （ C ） and oxygen （ 02 ）, hydrogen （ H2 ）, nitrogen （ N2 ） has a strong affinity. Welding properties of zirconium （Zr） and titanium （Ti） ; Currently： less actual civil engineering application, this article for acetic acid plant zirconium pipe welding material, analyzes the characteristics of zirconium welding thermal cycle, introduces the specific technical requirements of zirconium welding and welding essentials, and application of plant and field data, this paper expounds the zirconium pipe welding key technology ; Have great reference application value.
