摘要:
印度西孟加拉邦加尔各答Sagardighi电厂和Durgapur电厂建设工程3×300 MW机组锅炉高温过热器出口集箱,规格?准 609.6 mm×110 mm,采用国产钢材12Cr1MoVG钢,现场安装焊接采用印度焊接材料。结合该集箱厚壁、大直径管焊接的工艺特点,强调了12Cr1MoVG钢采用印度焊接材料焊接时,应注意充氩气保护、预热、层间温度及焊接线能量的控制,并采用多层多道焊和焊后热处理。实践证明,根据此焊接工艺能获得良好的焊接接头。
Abstract:
The φ609.6 mm×110 mm pipe is welded by adopting China domestic 12Cr1MoVG steel and India welding materials at site construction, which is used in 3×300 MW boiler high temperature super-heater outlet header of Sagardighi and Durgapur Thermal Power Plants, Kolkata, India . In combining with the process characteristics for large diameter and heavy thickness header,it stresses some precautions,such as filling argon protection,preheating, controlling interpass temperature, while using India welding material . It also uses multi-layer and multi-pass welding . The practice proves that using this kind of welding procedure can obtain ideal welded joints .
