In order to solve the problem that poor fabrication and low efficiency of vessel head insulation material, the manufacture standard and forming method of the vessel head are studied, several cutting plans are put forward to solve the fabrication problem of the vessel head insulation material. Through improving the transmission theory of the cutting machine, a new solution to solve the small-size pipeline rigid insulation material fabrication is put forward, and the processing efficiency and quality of the small-size pipeline insulation material are solved.
