Method for the production of short ends of thick-walled pipe lengths of different dimensions for offshore pipes and pressure vessels

摘要

A method for the production of short ends of thick-walled pipe lengths of different dimensions for offshore pipes and pressure vessels is characterised in that the sheet to be deformed is parallelogram shaped and cut to the required pipe length, is guided along the subsequent longitudinal edges of the pipe, passes into adjustable deforming rolls, and, after deformation and welding up of the helical seams and the swivelling out of a roll support, is removed axially.
