Abstract
A single piece of pipe connectable to a similar adjacent pipe and including a female end that is reinforced with a band. The pipe includes in one embodiment a male end having external threads, a female end having an enlarged exterior diameter, a first section at the female end having an interior diameter to receive a male end of the similar adjacent pipe, a second section at the female end having internal threads to mate with the external threads of the male end of the similar adjacent pipe. The first section is positioned to funnel the male end of the similar adjacent pipe to the second section, and the second section is positioned between an intermediate section and the first section. At least one reinforcement band is positioned circumferentially around at least a portion of the female end. The pipe is disconnectable from the similar adjacent pipe and reusable.
