T&H Lemont ships pair of motorized seam orientation stands

T&H Lemont recently shipped a pair of motorized seam orientation stands (SOS), model 280/6, to an international tube producer and fabricator. Model 280/6 is designed to work on tube in diameters from 0.750 to 3.500 in. and wall thicknesses from 0.028 to 0.250 in. 

SOS units compensate for drift in the weld seam’s location. Using two vertical rolls that are adjusted by the operator, the SOS aligns the seam at a specified location on the circumference, usually top dead center, to align the weld seam with inductors used for inline annealing, the sensors used for nondestructive testing, or other applications. It also assists in maintaining the tube’s straightness and in complying with any customer requests for a specific seam location. 

T&H Lemont manufactures manual and motorized SOS units. The manual version requires stopping the mill to adjust the seam location, which can be a trial-and-error process. When using the motorized version, the operator adjusts the seam location on the fly. The company manufactures SOS units that handle tube and pipe from 0.750 to 14 inches OD.
