To provide a method of manufacturing a sprinkler winding pipe and the sprinkler winding pipe which has improved execution efficiency in manufacturing or field working and has highly reliable leakproof water-tightness and electrolytic corrosion resistance.

In the sprinkler winding pipe 10, a pipe body 11 is a stainless steel pipe that is a flexible pipe of a series of continued lengthy bellows part 11a with flexibility. The pipe body 11a is cut as a pipe body 11b with prescribed length. Straight pipe parts 12, 13 are formed on both end parts of the pipe body 11b with prescribed length. The straight pipe part 12 on the one end is integrally assembled with a rotary nipple 14 with a male screw part 14a on the outer circumferential face via a rotatable mechanism. The straight pipe part 13 on the other end is integrally formed with a hexagonal socket 15 with a female screw part 15a on the inner circumferential face. A precoat type film forming layer 16 is applied onto the outer circumferential face of the male screw part 14a of the rotary nipple 14 and the inner circumferential face of the female screw part 15a of the hexagonal socket 15.
