The invention relates to the field of pipeline thermal insulation product forming, in particular to a forming process of a thermal insulation module with single-sided metal protection, which comprises the following steps: a, preparing a shell: a1, taking a metal plate, and forming an outer wall, an inner wall I, an inner wall II and a connecting wall with semicircular cross sections through a plate bending machine and a cutting machine, the first connecting part, the second connecting part and the third connecting part are in an arc plane shape, and the width of the first connecting part is equal to the sum of the second connecting part and the third connecting part. A2, one end of the outer wall obtained in the step a1 and the inner wall are coaxially welded into a whole through a first connecting part, the other end of the outer wall obtained in the step a1 and a connecting wall are welded into a whole through a second connecting part, the free end of the connecting wall is welded to a third connecting part
