The thing about welding tanks is that the failures stop posting so we only hear from the I did it not a problem if you do it this way crowd I have seen one brand new heating oil tank explode from welding (no purge used at all but weld only on foot support not actual tank body ) fortunatly no one was hurt but the flattened tank landed 300 feet Welding on a diesel tank? - Weld Talk Message BoardsThe thing about welding tanks is that the failures stop posting so we only hear from the I did it not a problem if you do it this way crowd I have seen one brand new heating oil tank explode from welding (no purge used at all but weld only on foot support not actual tank body ) fortunatly no one was hurt but the flattened tank landed 300 feet Welding diesel tank - Miller Welding Discussion ForumsA man died in an explosion at a dump-truck manufacturing plant in northwest Harris County on Thursday while welding a level gauge to a 500-gallon diesel fuel tank.Johnny Vollentine,59,a retired Houston firefighter,was working in an outbuilding behind Strong Industries,in the 13000 block of Ralph Culver,when the explosion occurred at 11:28

Automotive Gas Tank Repair J-B Weld

Step 1 Locate the leak and mark it with a pencil.Step 2 Clean the area around the leak.Use the sandpaper to sand the tank,covering a few inches around the leak.Take it down to bare metal.The sanding does two things - cleans any paint,rust,and road grime from the gas tank repair area,as well as gives the epoxy something to grab onto.Automatic Welding Machines for Storage Tank ConstructionHHM Oilfield Machinery and Automation Inc.based in Houston,Texas,designs and manufactures specialty welding machines for tank building.These are used in the construction of refineries and storage tanks of all kinds worldwide.The majority of our machines are handmade in our shop with no or little outsourcing!AWWA D100-11 Welded Carbon Steel Tanks for Water StorageSections 8 through 15 include welding,shop fabrication,erection,inspection and testing,foundation design,seismic design of water storage tanks,and alternative design basis for standpipes and reservoirs.Downloadable versions of current and historical standards are
