INSPECTION PIPE

To provide an inspection pipe having a structure for inspecting a transported object.SOLUTION: An inspection pipe 1 comprises: a pipe body 2 inside which powder falls; a deceleration member 3 provided within the pipe body; and an inspection window 4 that inspects the powder flowing in the pipe body 2, where the pipe body 2 is partitioned into a first path passing between the inspection window 4 and the deceleration member 3, and a second path on the opposite side of the inspection window 4, and an outflow port of the first path is narrower than an inflow port of the first path so that the powder passing through the first path is accumulated to a height of covering at least a part of the inspection window 4.SELECTED DRAWING: Figure 1 【課題】搬送物を検視するための構造を有する検視配管を提供する。【解決手段】内部を粉体が落下移動する管体２と、管体内に設けられた減速部材３と、管体２内を流動する粉体を検視するための検視窓４と、を備え、管体２は、検視窓４と減速部材３との間を通過する第１のパスと、検視窓４とは反対側の第２のパスと、に区画されており、第１のパスを通過する粉体が検視窓４の少なくとも一部を覆う高さまで堆積するように、第１のパスの流出口を第１のパスの流入口よりも狭く構成した検視配管１。【選択図】図１
