The process of spiral pipe mill consists of preparation, forming and welding. In this study, resistance forces in each working process are calculated theoretically, and the load, which is required to carry strip and pipe, is also taken into consideration. The total load is compared with the indicated load on main driving motor of spiral pipe mill, and both values are shown to agree well each other. Dynamical behavior in each working process in the spiral pipe forming is also analyzed.
