To provide a cutoff method of a fluid pipe which can cut off the fluid pipe in a box body while tightly surrounding a conduit part and a branch part of the fluid pipe by the box body.SOLUTION: A cutoff method of a fluid pipe 1 for cutting off a part of the fluid pipe 1 in a non-interrupted state has: a step in which at least a box body 5 tightly surrounds a conduit part 2a of the fluid pipe 1 and a branch part 2b branched from the conduit part 2a, and a branch straight pipe 4 connected to the branch part 2b; and a step in which a center drill 72b drills a position avoiding a seal material which is interposed between the branch part 2b and the branch straight pipe 4 by using a cutter 72 having a hole saw 72a and the center drill 72b in the box body 5, and the hole saw 72a cuts off the conduit part 2a of the fluid pipe 1 and the branch straight pipe 4 so as to be separable.SELECTED DRAWING: Figure 4
【課題】流体管の管路部及び分岐部を筐体によって密封状に囲繞し、この筐体内にて流体管を切除することができる流体管の切除方法を提供する。【解決手段】流体管１の一部を不断流状態で切除する流体管１の切除方法であって、少なくとも筐体５によって、流体管１の管路部２ａ、該管路部２ａから分岐する分岐部２ｂ、及び該分岐部２ｂに接続された分岐直管４を密封状に囲繞する工程と、筐体５内部にてホールソー７２ａ及びセンタードリル７２ｂを備えたカッタ７２を用いて、センタードリル７２ｂが、分岐部２ｂと分岐直管４との間に介設されたシール材を避けた位置を穿孔するとともに、ホールソー７２ａが流体管１の管路部２ａと分岐直管４とにかけて切除する工程と、を有する。【選択図】図４
