Abstract

<PICT:1062270/C1/1> A method of glass coating the internal surface of a tubular article comprises applying a ground coat glass composition to the internal surface, the said composition consisting of a glass frit mixed with 25 to 75% by weight of finely divided particles of a refractory material, heating the ground coat glass composition to a temperature below the melting point of the refractory material to produce a hard, non-sticky vitreous enamel coating, introducing an applicator into the tubular article, supporting a portion of the applicator upon the ground coat surface, depositing a cover coat glass composition upon the vitreous enamel ground coated internal surface, and uniformly fusing the cover coat composition to the vitreous enamel ground coat composition. A tubular article, e.g. a metal pipe, after having had its internal surface cleaned, has a ground coat enamel frit wet sprayed thereon, the pipe then being dried and placed in a firing furnace, to produce a ground coat enamel that is hard and non-sticky. The pipe 1 is supported and continuously rotated up a roller 3 in furnace 2. When the ground coat has matured a cover coat applicator 6 is inserted into the pipe whilst still in the furnace. The applicator rests upon the ground coat 5 of the pipe and has an auger 9 which deposits the cover coat frit 8 upon the ground coat as the applicator 6 is gradually withdrawn from the pipe. The pipe 1 is caused to continuously rotate during the application of the cover coat, which is fired as it is applied. The ground coat enamel has a basic composition of 35 to 55% by weight refractory materials, 1 to 10% alkaline earth metal oxides, 10 to 25% alkali metal oxides, 1 to 7% alkaline metal halides, 12 to 30% oxides selected from the group boron, copper, chromium, cobalt, manganese and nickel oxide, and an addition of 25 to 75% of a refractory material of oxides, borides, fluorides, nitrides, silicides or aluminides having a melting point above 1600 DEG F. The ground coat is fired in the range 1500 DEG to 1650 DEG F. and the cover coat matures below 1650 DEG F.
