ABSTRACT:
A method for forming a branch in a pipe made of polymeric material which permits a strong joint to be formed at the branch to another pipe. A system for carrying out the method includes heaters which soften the polymeric material in a highly localized manner. A forming member is pulled through the softened material to deform the pipe wall and form a branch. A method for making reinforced pipe joints in which pipe sections are force fit into each other is also disclosed.
