摘要:
采用SEM、TEM、EDX及金相分析等手段,对某气田集气干线工程的输气管道一直 管与弯管焊接处发生爆裂件进行了取样分析,发现该集气管道破裂失效属硫化氢应力腐蚀开裂,裂 纹起源于焊缝附近的直管母材内壁,与该直管的淬火、回火态的贝氏体+马氏体组织相关。
Abstract:
A broken gas pipeline is analyzed by means of SEM,TEM,EDX and optic metallography. It is testified that the main reason of the fracture is SCC resulted from H2S.
