Method of lining pipes, molds or other tubular articles with thermosetting plastic material

摘要

A method of lining a pipe with settable material including the steps of arranging the pipe with its longitudinal axis inclined at an angle to the horizontal, introducing a selected amount of liquid material into the pipe at a predetermined rate so that the liquid material flows down along the pipe, shifting the pipe to a horizontal position and spinning the pipe about its axis to distribute the material, spinning continuing until the material has set. The method is particularly applicable for lining pipes with polyurethane. For pipes with end flanges end faces of the lining material can be formed integral with the lining.
