PURPOSE: A four-way forging system for a pipe and a four-way forging method using the same are provided to gradually reduce the outer diameter of a pipe-shaped object through several times of forging processes. CONSTITUTION: A four-way forging system for a pipe comprises a support structure(100), a moving rail(110), left and right clamps(120,130), one or more supporters(140,141,142,143,144,145), a loader(150), a forging machine(200), an unloadeR(170), mandrels(250,270), and a transfer unit(260). The moving rail is formed on the support structure. The left and right clamps are horizontally moved along the moving rail. The loader loads a pipe-shaped object on the supporters or the left clamp. The forging machine forges the object fixed to the left clamp and/or the right clamp. The unloader unloads the forged object from the supporters or the right clamp. The mandrels are selectively inserted into the object. The transfer unit forcefully moves the mandrels.
