<p>The present invention refers to a method of manufacturing pipes welded longitudinally comprising longitudinal cutting of the primary material tape into tape for the pipes, profiling the tapes into pipes and longitudinal welding, characterized in that:
a) The primary tape is unreeled from the decoiler, wherein the decoiler is equipped with the photocells under and above of the coil of primary material tape and after the fixing of the coil in the coil-support of the decoiler an automatic control system adjusts the tape horizontally along a rotation axis, perpendicularly to the center line of the manufacturing line by the hydraulic cylinders till the coil is set centrally, in order to align symmetry line of the metal sheet of the primary material tape to the center line of the manufacturing line, wherein position of the coil of the primary material tape is controlled by the automatic control system through the usage of signals coming from the photocells, before cutting the metal tape into pipes.
b) Primary tape from phase a) is cut into sheets for pipes
c) Sheets for pipes from phase b) are transferred to the compensator or preferably through the compensating pit to the recoiler
d) Sheets for the pipes are transferred from the compensator or the recoiler to the profiling machinery
e) Profiled tape for the pipes is transferred to the longitudinal welding
f) The pipe from phase e) is conditioned in a cooling agent</p> |
