<p>Disclosed herein is a pipe joint for connecting pipes. The pipe joint comprises separate joint bodies, each of which has a pipe fixing portion comprising a plurality of diamond or pyramid-shaped protrusions formed on an inner surface thereof to provide a strong coupling force with respect to the pipes in order to prevent the pipes from being released from the pipe joint. Since conventional pipe joint provides a low coupling force, there is a disadvantage in that, when connecting stainless pipes, aluminum pipes or coated pipes using the pipe joint, these pipes can be easily separated from the pipe joint due to its low coupling force, causing many problems in assembly of construction. The present invention is designed to solve the problem of the conventional pipe joint, and provides an environmentally friendly pipe joint.</p> |
