METHOD OF MANUFACTURE OF MAIN ACCORDING TO ANALYTICAL INFORMATION Russian patent published in 1999 - IPC

FIELD: shipbuilding; manufacture of pipe line for shiprepair, power construction, heavy and chemical engineering. SUBSTANCE: method includes procedure of marking out points of fitting the flanged joints, cutting and bending the pipe and assembling it with flanges. The method includes also procedures of fitting simulators of standard flanged joints at marked-out points, measuring the linear and three angular sizes defining the relative position of simulators, measuring the coordinate of end point of each specified bend of pipe but for the first and least ones which are accompanied by subsequent dismantling of simulators and entry of the information into the computer. The computer is used for determination according to the program of sizes of linear sections of main, angles of bends and angles between planes of bends, after which the pipe is cut and bent according to these sizes. It is good practice to fit simulators of flanged joint having at least two diametrical holes for bolted joint coaxially relative to geometric axis of standard flanged joint and to secured them by hangers on tacks. EFFECT: reduced labor consumption due to fuel analytical information pertaining to configuration of pipe. 2 cl, 1 dwg
