A method and an apparatus for making a pipe, and a pipe, wherein the pipe is made from a plastic feedstock pipe by expanding it against a mould. In the first step, that portion of the plastic feedstock pipe ( 4 ) which is to have a greater diameter than the rest of the pipe is partly expanded. Only after this is the entire plastic feedstock pipe ( 4 ) expanded against the mould ( 1 ).
