On-line Straightening of MF Normalized Welded Pipe

In line with the phenomenon that the bending occurred in the soldering seams of welded oil pipe and boiler pipe during their heat treatment of MF normalization, a Turkey-head stand adjustable in vertical, horizontal and peripheral directions is suggested to be added to the sizing section in order to perform a reverse bending in the soldering seams of welded pipes, aiming at their on-line straightening.
