摘要： The method of forming a seamed metal tube (20c) having a metal coating (56) of this invention includes galvanizing the strip (20) prior to welding. The strip (20) is then formed into an open seam tube (20b) and welded in an inert atmosphere with the seam (71) located in the lower portion of the tube. Finally, the metal coating (56) is caused to flow downwardly over the seam (71), coating the seam (71) by several means. In one embodiment, the strip (20) is preformed into an arcuate shape (20a) and galvanized, wherein the zinc coating (56) increases in thickness toward the lateral strip edges (48), such that the coating (56) will flow over the seam (71) following welding. The tube (20c) may also be reheated following welding, preferably in an enclosure (78) containing an inert atmosphere which includes the weld apparatus (62). In another embodiment, an inert gas is directed over the inner and outer surfaces of the tube (20c), adjacent the seam (71), driving the molten metal downwardly over the seam (71) to coat the seam (71). In another embodiment, the lateral edges (48) of the strip (20) are formed with indentions or grooves (188) directed toward the lateral edges (48) which direct the molten metal downwardly over the seam (71).

摘要： A continuous tube forming and coating process and apparatus, wherein the tube is formed and welded with the seam located at the bottom of the tube and the painted surface on the inside of the tube. An applicator (72) coats the inner surface of the seam following welding preferably in an inert atmosphere. An impeder (54) includes ferrite rods and circulating coolant and a paint applicator tube which extends through the impeder having a nozzle which applies coating over the seam. A galvanizing apparatus having a sealed galvanizing tank (98) which receives the seamed tube below the level of the molten zinc and which is enclosed within a sealed housing and gas pressure in the galvanizing tank is greater than pressure in the housing. The galvanizing apparatus includes inert gas seals (116) which may be also used to as a wiping nozzle.

摘要： The method of forming a coated seamed metal tube (20c) of this invention is particularly, but not exclusively, adapted to existing continuous tube forming mills, wherein the tube (20c) is formed from a metal strip (20) and welded with the seam (71) located in an upper portion of the tube (20c). In the process of this invention, at least one surface of the strip (20) is coated with a metal coating (21) prior to forming and welding. The tube (20c) is then turned to relocate the welded seam (71) in a lower portion of the tube (20c) and the lower portion of the tube (20c) is then reheated to melt the metal coating (21) and the metal coating (21) then flows downwardly over and coating the welded seam (71). In the most preferred continuous or in line process of this invention, the tube (20c) is continuously spirally twisted following welding to locate the seam (71) in a lower portion of the tube (20c) adjacent a heater (110) and the tube (20c) is then heated by the heater (110) to the melting temperature of the metal coating (21), causing the coating (21) to coat the seam (71).

摘要： A method of forming a seamed metal tube (20c) having a metal coating (56) on at least an inside surface of the tube (20c) from a continuously moving, relatively flat metal strip (20a) is disclosed. The primary feature of the inventive process is the step, after forming and welding the seamed metal tube (20c), of locating the seam in a lower portion of the tube (20c) and reheating at least that lower portion of the tube (20c) to melt the coating (56). The coating (56) is thereby caused to flow downwardly over and to coat the inner surface of the seam. The result is a seamed tube (20c) with a more corrosion resistant seam region.
