Analysis of thin-walled stainless steel container and stainless steel welding applications
Widely used in conventional design container plate, so more manual welding stainless steel weld, 6mm-8mm plate on top can be submerged, thin-walled stainless steel container and more water-cooled TIG welding, TIG welding is argon inert gas protection of the weld in the welding process and air separation, it does not protect the weld from oxidation. Water is not rust because of stainless steel as the main element chromium (Ni-304 accounted for most of the cost, is to increase rigidity), chromium in the second high-temperature welding process may be due to poor protection of argon gas, wire quality is not high and oxidation, by water cooling, while reducing the welding temperature, sheet easily deformed; two is not easy to produce chromium depleted zone.
Widely used in industry, coil, riveter technology improves, so the selection can greatly reduce the thickness of the container. To 300 m3 tank, for example, on the top, bottom and the next two lower cylinder using 3mm thick plate, and the remaining tube 2.5mm thick plates are used, strength and rigidity no problem. In April 2008 we produced 28 Mianyang Feng Valley station 280 cubic meters of tanks, through the 5.12 earthquake, no problems, it also eliminates the fear of thin-walled tank because some customers can self-respect, typhoons, earthquakes and other factors insecurity concerns.
The choice is with the thickness of the pressure vessel and process design experience in the book. Such as Sichuan JLF wine this year we made 500 cubic meters of new storage tanks, pressure vessels through the process of design book design, the thickness of the bottom should be greater than 3.63mm, we use a 4mm. On the one hand consider the static pressure, 10-meter-high tank bottom is generally static pressure 0.1mpa; the other hand consider the rigid, that is not deformed, mainly by riveter, because the multi-use coil, carefully skilled riveting Copyright China Wine Online work can be wrong side of the volume control very well, protect the smooth transition. Welded thin-walled containers are most afraid of group phenomena in the waist, prone to stress, transport of wine and cleaning is easy to produce due to temperature changes in the phenomenon of flat cans.
