手。 A synthetic resin sewer pipe that branches off from the main sewer pipe and is located near the boundary between a public road and a residential area.
Connect the synthetic resin straight pipe for the cleaning port through the pipe joint.
In the small-diameter square mounting structure for vertically installed sewer pipes, the pipe joint has a double-ended sleeve having substantially the same structure as the sleeve for the main part and branch parts, which have double-ended sleeves of a standardized 90° large-bend Y joint. A main part and a branch sleeve are provided, and the upstream ridge line of the branch part extending between the double-ended sleeves of the main part is oriented substantially perpendicularly toward the upstream side of the double-ended sleeve. The drainage pipe is characterized in that the downstream ridge line is formed in a substantially straight line toward the downstream side of the double-ended sleeve, and the space near the base of the branch part is expanded as much as possible. Pipe fitting for small diameter sewage basin.
