information without intervention from an operator or a surge.The system of claim 1, wherein the pipe cutting unit measures a length and thickness of the original pipe and cuts the original pipe with the pipe cutter, the measured length and thickness of the original pipe are transmitted to the control unit, and information on a pipe spool to be manufactured, input to the control unit, is recorded in the spool pipe.The system of claim 2, wherein when a residual pipe, which is a portion of the original pipe remaining after manufacturing the spool pipe, is longer than a length of another spool pipe to be manufactured, the control unit is configured to cut the residual pipe with the pipe cutter and to manufacture the residual pipe as another spool pipe, andwhen the residual pipe is shorter than a length of another spool pipe to be manufactured, the control unit is configured to discharge the residual pipe from the pipe cutting unit and to manage the residual pipe separately.The system of claim 1, wherein the spool pipe bevel processing unit measures a shape, circularity, a thickness, and a center of an end of the spool pipe and transmits the measurements to the control unit, and the control unit determines whether to process the end of the spool pipe, and when it is determined that it is possible to process the end, the control unit performs processing of the end of the spool pipe, and when it is not possible to process the end, the control unit discharges the spool pipe from the spool pipe bevel processing unit.The system of claim 1, wherein the spool pipe bevel processing unit allows a J-shaped welding bevel for automatic robot welding or a V-shape welding bevel for manual welding to be formed in the end of the spool pipe by the spool pipe bevel processing device, and performs processing of inner and outer diameters of the end of the spool pipe in which the welding bevel is formed.The system of claim 1, wherein the connection member bevel processing unit measures a shape, circularity, a thickness, and a center of the end of the connection member and transmits the measurements to the control unit, and the control unit determines whether to process the end of the connection member, and when it is determined that it is possible to process the end, the control unit records information on a pipe spool to be manufactured, input to the control unit, in the connection member, and performs processing of the end of the connection member, and when it is determined that it is not possible to process the end, the control unit discharges the connection member from the connection member bevel processing unit.The system of claim 1, wherein the connection member bevel processing unit allows a J-shaped welding bevel for automatic robot welding to be formed in the end of the spool pipe by the connection member bevel processing device, and performs processing of inner and outer diameters of the end of the connection member in which the welding bevel is formed.The system of claim 1, wherein, to fit up bevel surfaces and to perform no-tack welding by a robot in the straight pipe spool manufacturing unit or the three-dimensional spool manufacturing unit, the spool pipe bevel processing unit allows a J-shaped welding bevel to be formed at an end of the spool pipe by the spool pipe bevel processing device, and the connection member bevel processing unit allows a J-shaped welding bevel to be formed at an end of the connection member by the connection member bevel processing device.The system of claim 8, wherein the spool pipe bevel processing unit performs processing of inner and outer diameters of an end of the spool pipe in which the welding bevel is formed, and the connection member bevel processing unit performs processing of inner and outer diameters of an end of the connection member in which the welding bevel is formed.The system of claim 8, wherein, in the straight pipe spool manufacturing unit, bevel surfaces are fit up as the spool pipe is gripped by the straight pipe spool welding site and the connection member is gripped by the handling robot, a root portion between the spool pipe and the connection member is welded by a root-welding robot included in the welding robot, and thereafter, the other portion between the spool pipe and the connection member is welded by a fill and cap welding robot included in the welding robot.The system of claim 8, wherein, in the three-dimensional spool manufacturing unit, bevel surfaces are fit up as the straight pipe spool is gripped by the
