Abstract

927,409. Making tubes. CONTINENTAL CAN CO. Inc. Dec. 8, 1960, No. 42208/60. Class 83 (2). A method of making a composite stock having metal layers 12 separate and non- welded to one another, comprises preparing a metal billet having an internal channel containing a soluble weld preventing resist material 13 which remains solid at a hot-rolling temperature for the metal and with the metal of the billet enclosing the resist material, heating to the said hot-rolling temperature for the metal and extending the surface area of the billet and thereby reducing its thickness wherewith the metal and resist material are conjointly extended to form a body having surface layers of metal connected at the edges of the reduced billet and an intervening internal layer of the residue of the resist material, separating the metal layers, and washing the resist material from the metal layers. Sodium chloride, sodium or potassium dichromate and tri-sodium phosphate are given as examples of resist materials. The production of single- and multiple-bore tubes is described.
