| 摘 要： | 煤气化过程中变换气输送常采用不锈钢管道，由于高温含硫介质及高残余应力的共同作用，管道易产生应力腐蚀而导致开裂破坏。现采用表面含金化处理的渗铝钢管，并研究解决了其焊接等关键问题，经三年多运行证明，该技术是成功的。

| Abstract: | The stainless steel pipes were used for feeding shift gas in coal gasification. But the pipes are usually destroied as a result of the stress corrosion cracks due to the cooperation of the fed medium of high temperature and high sulphur content, and the high residual stress. The aluminized steel pipes with surface alloying treatment are used to the process and some key problems, such as welding, are solved,3-years safe working shows that the aluminized steel pipes meet with full success. |
