Stainless steel Panel Tanks
Different Tanks For Different Needs
One size and style does not fit all. At Sekisui, we have consistently listened and responded to the demands of our customers who desire special products for special situations.
Type: On-site assembly type
Capacity: 1-3000 tons
Material: SUS444-SUS329J4L
Features
"Bolt-assembled design" with excellent on-site workability
The panels are easy to transport, assemble, and install, allowing the overall construction period to be significantly shortened. Installation is particularly efficient in narrow or elevated locations, which simplifies schedule management and helps ensure delivery deadlines. In addition, new installation or replacement can be carried out easily regardless of the site conditions or tank size.
Highly safe, as no welding or open flames are required
Because it is a bolt-assembled system, no open flames—such as welding—are required on-site, ensuring a high level of safety, especially for indoor work such as in basements. Furthermore, since there is no need for pickling welded areas or disposing of waste cleaning solutions, there is no environmental impact, greatly contributing to an improved on-site environment.
Box-frame design providing superior earthquake resistance
The tank’s earthquake-resistant structure is our unique externally reinforced box-frame design. This high-rigidity structure is engineered to mitigate sloshing and withstand seismic forces. Since there are no internal reinforcements, equipment such as heat exchangers can be installed, and cleaning and maintenance inspections are greatly simplified.
Stainless steel panel tank with excellent corrosion resistance
In general, the corrosion resistance of a metal is determined by how easily it ionizes in an aqueous solution (its ionization tendency). This is represented by a scale known as the “standard electrode potential.” In other words, metals that ionize easily (those with low standard electrode potential) have low corrosion resistance, while metals that ionize less easily (those with high standard electrode potential) exhibit high corrosion resistance.
Figures 1 and 2 show typical corrosion forms of stainless steel and demonstrate that Stainless Steel 444 is a superior material compared with other stainless steels.
Recycling of stainless steel panel tanks
To recycle scrap into equivalent stainless steel without compromising quality, it is essential that the material can be sorted by grade and separated based on chemical composition (Stainless steel 444 and Stainless steel 329J4L).
❶The panel plates used in the tank are labeled with their respective chemical compositions (Stainless steel 444 or Stainless steel 329J4L), making sorting straightforward.
❷The bolt-assembled design allows easy disassembly and smooth separation of panels by chemical composition.
Standard stainless steel panel
The standard specification for bolt-assembled stainless steel panels is Stainless steel 329J4L on the gas-phase side and Stainless steel 444 on the liquid-phase side. However, if residual chlorine is low and operating conditions are not severe, Stainless steel 444 can also be used for the gas-phase side as an optional specification. Please contact us separately if you would like to use this option.
