The invention discloses a centrifugal manufacturing method of a melt-processable polytetrafluoroethylene PFA inner lining and a centrifugal manufacture method of an inner lining steel pipe. The PFA inner lining comprises the following components: 100 parts of PFA, 2-5 parts of talcum powder, 1.2-1.5 parts of industrial vaseline, 1-2 parts of stearic acid and 4-4.5 parts of zinc oxide. The invention adopts a centrifugal force principle to manufacture the PFA inner lining steel pipe, the manufacturing method does not need to be matched with a corresponding mould and corresponding high-pressure shaping mechanical equipment, the manufacturing cost is saved, the PFA thermal stress is eliminated, the generation of cracks is avoided, and the combination of a PFA inner lining layer and the inner wall of the steel pipe is firmer.
