The invention relates to the field of steel pipe preparation, and discloses a steel pipe processing method with a high yield. The continuous casting billet is used as a raw material, and the following steps are followed in sequence: heating, piercing, surface machining, annealing, pickling, phosphating, and saponification , Rolling preheating, rolling, cooling, the steel pipe produced will not crack, the quality is high, the yield is high, and the production cost is low; the piercing temperature is related to the piercing rate and the cracking degree of the steel pipe, and the appropriate piercing temperature can ensure the piercing efficiency. Avoid cracking of the steel pipe, and also avoid the production of waste products. The annealing process of the present invention can overcome the defect that the inner or outer surface of the steel pipe is easy to crack. Since the steel pipe billet is first put into the furnace and kept at 750-760°C, the steel pipe and The temperature in the furnace is consistent, and then staged annealing treatment and cooling are performed to stabilize the performance of the tube billet.
