As shown in the figure, after fitting and gluing the flanged short cylinder parts to the upper and lower ends of a transparent tube made of glass or synthetic resin, the flanges are attached to the upper and lower connecting pipes with a sealing member interposed to form a V-shaped cross section. In addition, in order to avoid poor visibility due to powder adhesion to the inner wall surface due to static electricity generated in the transparent tube, electrical conductivity is established between the upper and lower short tube sections. Electrostatic phenomena are eliminated by making the upper and lower connecting pipes electrically conductive by welding and connecting them with magnetic metal pieces, but in order to eliminate this electrostatic phenomenon, adhesives and adhesives are used during the manufacturing process. Not only is the welding work and painting process extremely troublesome, but also the quality can only be stabilized by skilled workers, resulting in a rather expensive product.

After forming in advance the conductive parts 6 coated with conductive powder such as silver powder, for example, in two places on the left and right in the vertical direction, the upper and lower joint pipe bodies 7 made of rubber or synthetic resin are formed.
8, connecting portions R1 and R with the upper and lower connecting pipes 9 and 10
2 are fitted and connected in such a way that they become electrically conductive, thereby forming a see-through section 1 for inspection in a powder transfer pipe. The application of the conductive portion 9 includes adhesion or baking and welding of a thin conductive portion.

After coating and forming the conductive portion 6 covering appropriate portions of the upper and lower connecting pipes 9 and 10, the powder particles are connected to the upper and lower connecting pipes 7 and 8 by the upper and lower joint pipe bodies 7 and 8 in order to conduct electricity at the connecting parts R1 and R2. Transparent part 1 for inspection in body transfer piping
Therefore, the process of coating the conductive portion 6 on the circumferential surface of the transparent tube body 2 can be mass-produced using only the transparent tube body 2 itself, and the upper and lower connecting tubes 9,
10 can be assembled with the joint tubes 7 and 8 using a simple fitting and connecting means, resulting in easy assembly and disassembly, making the structure simpler than conventional products, making it easier to manufacture and mass-produce. It is a device that exhibits excellent practical effects such as excellent performance and can be provided to the market at a low price. If the joint tubes 7 and 8 are made of a conductive material, the conductive portion 6 coated on the circumferential surface of the transparent tube 2 does not need to extend to the upper and lower end surfaces 4 and 5.
