摘要
对电站锅炉超超临界机组用小口径钢管SA213-T92焊缝进行740℃～760℃保温1h热处理状态下在常温及510℃、620℃工艺性能试验及2次产品试生产。试验结果表明,焊接接头性能指标满足技术规范要求,该结果可以做为一项技术储备或发展方向。
The text is a procedure property experiment of tube SA213-T92after postweld heat treatment of holding one hour at 740 ～760temperature,which used for ultrasupercritical boiler,and fish product-trial for two times.The experiment results indicate that performance index of welding joint are according to technical regulation ,this results are considered a technical storage or development direction.
