A low-plastic material corrugated pipe forming device comprises a heating system, a pressure exciter, an electro-hydraulic servo and a forming die. The heating system is an atmosphere furnace with three sections of partitioned temperatures independently controlled; the pressure system consists of a pneumatic supercharger, a pressurizing pipeline and a needle valve; the forming die is composed of a lower fixing base, a guide column, an inner die piece, an outer ring, a limiting bolt, an upper fixing base and other parts. The method for forming the corrugated pipe by the low-plastic material mainly comprises the following steps of: 1, heating a material tensile test piece by adopting an atmosphere furnace, and obtaining material physical property parameters under a high-temperature working condition by applying a material tensile testing machine; secondly, physical property parameters of the high-temperature working condition material are input into finite element simulation software, simulation calculation is
