Manufacturing Method for Membrane metal panel of insulated cargo tanks of LNG carrier

摘要

PURPOSE: A method for manufacturing a membrane metal panel of an insulating tank for a ship is provided to obtain superior stress distribution and durability by forming longitudinal and transverse corrugations that are accurately symmetrical with each other. CONSTITUTION: A method for manufacturing a membrane metal panel of an insulating tank for a ship comprises a step of forming a corrugation pattern(120) composed of longitudinal corrugations(121) and transverse corrugations(123). The corrugation pattern is simultaneously in a predetermined area through a single process using a mold in which longitudinal and transverse corrugations are arranged in a lattice form.
