They do make rockets out of the pipe.

Look up Qassam rockets.
The latest date I could find for
the Hamas Kasam rockets’ use
was in 2009.
This from an article I found on
the wiki;
“Inbar noted a statement by Hezbollah leader Hassan Nasrallah in December 2020 when he said: “Most of the weapons, missiles and facilities that Palestinian resistance groups have in Gaza are supplied by Iran’s Islamic Revolutionary Guard Corps’ Quds Force. The Islamic Republic used its diplomatic relationship with Sudan to establish a weapon factory for Gaza in Sudan.”
