Abstract: A production line for manufacturing high temperature alloy furnace pipes and piperows characterized in that it comprises of a casting department production line, a machining department production line and a welding department production line. In the casting production line, a pipeline section is casted via the process of centrifugal casting. In the machining process, the tectorium of internal bore of the pipeline section is removed via the process of boring hole and a groove is machined via a digitally controlled pipe machine. In the welding process, the pipeline sections are welded into a long pipe via the process of argon-arc welding, and flanges and pipe fittings are welded to make a furnace pipes, and further, long furnace pipes are welded into piperows. Finally, quality products of furnace pipes and piperows are ensured through a series of testing equipments and testing procedures.
