摘要： A process for reducing a raw steel pipe obtained by a solid phase bonding pipe manufacturing method or a welding pipe manufacturing method is carried out by heating the steel pipe to a temperature in excess of 100 DEG C and lower than 800 DEG C before it is reduced, restricting the temperature of the steel pipe during a rolling operation to a level in a specific range, controlling the temperature difference of the steel pipe in the circumferential direction thereof at the inlet side of a reducing mill to be in a specific range, and also controlling the temperature of the steel pipe between the stands of the reducing mill. This enables the steel pipe to be reduced with a low load with the work hardening effect minimized without deteriorating the properties of the surface thereof, and the dimensional precision of the product pipe to be maintained at a high level.
摘要翻译：通过固相接合管制造方法或焊接管制造方法得到的原料钢管的还原方法，是在将钢管冷却至超过100℃且低于800℃的温度下进行的在轧制操作期间将钢管的温度限制在特定范围内的水平，将还原磨机的入口侧的钢管在其圆周方向上的温差控制在特定范围内，并且还控制还原轧机机座之间钢管的温度。这使得钢管能够以低负荷减小加工硬化效果最小化，而不会使其表面的性能劣化，并且使产品管的尺寸精度保持在高水平。
