Vertical Up Welder - Manufacturer of Cutting,Welding and

The Vertical Up Welder (VUP),a single pass Vertical-Up welder (VUP) can complete 10-12 vertical seams on a field erected storage tank with 8' tall x 1 thick seams in one work shift.X-Ray quality welds with one operator and one machine.Vertical Tank WelderThe Automatic Vertical Tank Welder (12 O'clock welder) is a submerged arc-welding machine designed for welding the vertical seams of oil,gas,and grain storage tanks.The machine travels along the top of the tank's plates and welds the vertical seams.US2126997A - Method of making storage tanks and similar METHOD OF MAKING STORAGE TANKS AND SIMILAR WELDED STRUCTURES Original Filed March 30.1934 3 Sheets-Sheet l Fig.I 59 53 S 83 85 52 22 so 52 Q lNVENTOR ANDREW A.KRAMER Au 16,1938.P A.A.KRAMER 2,126,997 .METHOD OF MAKING STORAGE TANKS AND SIMILAR WELDED STRUCTURES Original Filed March so.1934 s Sheets-Sheet 2 ATTORNEY 1938.A1 A.

Vertical Configurations.These are steel atmospheric tanks intended for aboveground storage of non-corrosive,stable,flammable,and combustible liquids that have a specific gravity not exceeding that of water.Maximum allowable working pressure is 0.5 psig as measured from top of tank.Vertical tanks may be of single or double wall construction.The next generation of vessel and tank productionThe decoiler and rolls then move back several feet to allow room for technicians to clean and tack-weld the edges,creating the initial shell form.At this point the tank shell is rotated to the vertical seam welder incorporated in Station 1.There,the shell is clamped and a system with a remote operator interface welds the vertical seam.The next generation of vessel and tank productionThe decoiler and rolls then move back several feet to allow room for technicians to clean and tack-weld the edges,creating the initial shell form.At this point the tank shell is rotated to the vertical seam welder incorporated in Station 1.There,the shell is clamped and a system with a remote operator interface welds the vertical seam.
