The specifications of the nine-hole threading pipe include 9*32 and 9*28. The apertures of the nine-hole threading pipe are equal, with a length of 6 meters per pipe. It replaces the original single-hole row pipe, saving labor and effort. The material of the nine-hole threading pipe is PE, which is lightweight and thick, making it an indispensable buried pipe material in communication engineering. The nine-hole threading pipe is suitable for various communication industries, such as municipal engineering, street light threading projects, residential area renovation projects, road-crossing buried threading projects, and water conservancy projects. The nine-hole threading pipe has multiple holes, allowing for reserved pipe holes and improving the utilization rate of communication holes.

The three major requirements for the nine-hole threading pipe project acceptance:
(1) The quality of pipes and pipe fittings should comply with current standards.
(2) Valves should be installed upright and operate flexibly.
(3) After water pressure testing, all pipes, valves, and joints should show no signs of water seepage or leakage.
