Abstract
A pipe-welding mill for production of coiled pipes from coiled strips comprises a coil preparation section including unwinders disposed in a manner allowing displacement thereof in a direction perpendicular to the direction of pipe movement, and a magazine including a reel with set-up coils, the mill further including a strip coupler, shaping, welding, and drawing stands, a coiling arrangement with bending rollers, and cutting and receiving arrangements, the components being successively installed in the direction of pipe movement. Guide or receiving rollers of the receiving arrangement are located on a platform installed in a manner allowing the platform tilt with respect to the axes of the bending rollers, the receiving rollers being connected to the output shaft of the drive of the bending rollers through a universal joint.
