A pipe mold produces plastic pipe with an internal wall having a first wall portion and a second wall portion. The pipe mold, includes a cooling plug to assist in setting the pipe wall. The first wall portion of the pipe wall travels over and is in contact with the cooling plug applying heat directly to and providing a first temperature control to prevent access of cooling of the cooling plug. The second wall portion of the internal pipe wall travels over and is spaced outwardly away from the cooling plug. The pipe mold includes a second temperature control which operates in preventing the access of plug cooling as the second wall portion of the internal wall of the pipe travels over the cooling plug.
