Definitions
- Presented invention refers to a method of manufacturing the pipes welded longitudinally.
- Presented invention finds its application in the building industry for manufacturing of the welded pipes, for instance metal or steel pipes.
- the metal pipes are commonly used structural elements in the building industry.
- Commonly known method of improvement of the structural strength used for the pipes is a well-known method of bilateral welding of the joined edges of a metal sheet. This method is used for instance in the manufacturing of the pipes used for a gas transmission - method DSAW: Double Submerged Arc Welded.
- the international patent application W02010102607 presents a method of manufacturing of the big diameter pipes with the usage of DSAW method as well as a method of a quality inspection of welding.
- Other commonly known method of manufacturing of the welded pipes is an induction welding method.
- DSAW MIG /MAG also this method requires a continuity of supplies of a metal sheet for the profiling process.
- the subject of the presented invention is the method of manufacturing of the pipes welded longitudinally that considers longitudinal cutting of a primary material tape on the sheets entering to the process, profiling of the sheets on the pipes, longitudinal welding characterized in that :
- a special compensator which is buffering the metal sheets that are possibly as long as feasible and that allows also joining (by welding) the following metal sheets during the continuous production.
- the compensator tape winds horizontally in the coil through winding consecutive external layers and for the profiling it is taken from the internal layer.
- a tape can be obtained from the internal coil from the compensator in the continuous way while the external coil can be supplied in the discrete way - so there is a compensation between continuous run on the output and discrete run in the input. Thanks to the above, a continuous manufacturing process can be kept that allows to avoid the technological stoppages dedicated for the reloading of the coil of primary material tape (it is possible to join tapes of different material thicknesses and different widths but in a limited range) and minimize production of the pipes that are of unsatisfying parameters. Moreover, centering of the beginning of the sheet prevents a sloped cutting and minimizes scrap at edges of the primary material tape.
- the compensating pit allows simultaneous winding of two coils on one shaft with the usage of higher number of coils in case of materials of different thicknesses.
- Method of manufacturing of the pipes welded longitudinally includes: cutting the primary material tape into tapes for the pipes, profiling the tapes for the pipes and their longitudinal welding.
- Primary material tape was unreeled from the decoiler, whereas the decoiler was equipped with the photocells under and above the properly fixed coil of the primary material tape and when it was already fixed in the coil support, the automatic control system has adjusted the tape horizontally along a rotation axis, perpendicularly to the center line of the manufacturing line by the hydraulic cylinders till the coil was set centrally there were aligned symmetry line of the metal sheet of the primary material tape and the center line of the manufacturing line, wherein the position of the coil of the primary material tape was controlled by the automatic control system through the usage of the signals coming from the photocells, before cutting the metal tape into pipes.
- the primary tape was cut into the sheets for the pipes and the obtained tape was transferred through the compensating pit to the recoiler and successively unreeled to the compensator and successively was transferred to the profiling machinery.
- So profiled tape for the pipes was transferred to the longitudinal welding.
- Welded pipe was conditioned in a cooling fluid.
