Abstract
PURPOSE: To surely, tightly apply a lining material to the inner surface of an irregular shape, by placing the lining material so as to face to a closed inner surface of the irregular shape, by giving a temperature difference to two materials in order to enlarge the gap of two materials, by plastically expanding the lining material so as to tightly contact with the inner surface of the irregular shape, and by giving a temperature difference reverse to the said temperature difference to two materials.
CONSTITUTION: A stainless steel pipe 2 of outer diameter Di is inserted into a carbon steel outer pipe 1 of inner diameter Do which are then bent into a prescribed shape. A coil heater is wound around outer surface of the pipe 1 in order to heat it, and cold water is passed through inside of the pipe 2 in order to cool it; as a result, the diameter Do is expanded to Doh and the diameter Di is shrunk to Dic. After that, the heating and cooling are interrupted, a pipe expanding force F is applied to the pipe 2 using the cold water held inside; hereby, the pipe 2 is expanded picturing a strain curve (a)W(b)W(c); after the outer diameter of the pipe 2 becomes equal to the diameter Doh, two pipes 1, 2 are expanded together in one body, and the pipe 1 pictures a strain curve b'Wc' because of a difference between the yield stresses. When the inner diameter of the pipe 1 becomes DB, the force F is released; hereby, the pipe 1 shrinks from c' to e', and the pipe 2 from (c) to (e). Then, the internal cold water is removed from the pipe 2, and a water jet is applied to the outer surface of the pipe 1; hereby, the pipe 2 is dehydrated and its temperature is raised, and the pipe 1 is cooled; as a result, the diameter difference between two pipes is further increased so that a tight lining is completed.
