摘要： This invention provides a process for producing a seamless pipe while effectively suppressing carburizing which occurs in a seamless pipe without affecting the operation. The production process comprises the steps of cleaning a transfer device disposed between a lubricant coating device (7), which is disposed at least in the step of transferring a mandrel bar (B), and a mandrel mill (8) on its inlet side, cleaning the mandrel bar (B) subjected to stretch rolling on the upstream side of the lubricant coating device (7), and coating a nongraphitic lubricant onto the mandrel bar (B) by the lubricant coating device (7). In the production of the seamless pipe, the transfer device and the mandrel bar (B) are washed so as to satisfy formulae (1): 0.08 × C1 + 0.05 × C2 ≤ 3 and (2): 3 ≤ C1 + C2 ≤ 50 wherein C2 represents the amount of graphite deposited on the surface of the mandrel bar (B) before stretch rolling, g/m2, and C1 represents the content of carbon in an organic binder in the lubricant, g/m2.
