The form includes a body having a leading part and a trailing part, a hole in a leading side of the leading part and a channel in the body communicating with the hole. The body has a diameter at the leading part that is similar to the inner diameter of the pipe to be lined and greater than the diameter at the trailing part. The channel has at least one peripheral opening positioned rearwardly of the leading part of the form at a position to discharge lining material from the channel around the trailing part of the form and onto the interior surface of the pipe. The form is preferably provided with an attachment on the leading side for a tube supplying flowable settable lining material to and through the hole. Another embodiment relates to a method of producing a lining in a pipe which comprises supplying flowable settable lining material to the form while pulling the form through the pipe.
