摘　　要：介绍了石化工业每年需用钢管20万t，其中相当部分可采用焊管；由于炼钢、轧钢、焊接及检测设备的进步，以焊管代无缝钢管已取得一定成功；指出焊管比无缝管具有较大的价格优势，在当前市场经济和石化工业战略重组形势下，给直缝焊管的使用带来了有利契机．The oil and chemical industry needs 200 thousand tons steel pipe every year. Among them, the welded tubes occupies a suitable portion. The seamless pipe can be successfully instead by welded tubes because of technique progress in steel making, rolling, welding....... Owning to the cost superiority, the welded tubes will be used more and more in reengineering of oil and chemistry industry.
