摘要 |
A method of forming a branch in a pipe made of polymeric material that allows a joint to another pipe to be formed at the branch.The method comprises the following steps: - making a hole in the wall of a pipe of polymeric material - heating the pipe surface by means of a liquid softening the polymeric material in a highly localised manner. - pulling a cylindrical former or pin having a conical nose through the softened material to deform the pipe wall against a mould or collar to thus form a homogenous branch.A system for carrying out the method is also disclosed. |
