Rectangular Water Tanks Application
Precise Welding Technology

Precise Welding Technology

The tank interface is welded via argon arc welding, which includes water-wave welding and closed weld. Stainless steel welding materials are same to stainless steel tank materials. The welding effect is good, and it can withstand pressures of up to 6 mpa.

Types of Rectangular Stainless Steel Water Tanks We Offer

  • Single-Walled Tanks- These are the most basic stainless steel tanks, usually rectangular in shape. Having a single wall protects the tank from corrosive substances on both the internal and external surfaces.
  • Double-Walled Tanks- Depending on where the corrosion resistance is required, double-walled tanks can have one or both walls made of stainless steel. It includes insulation between the walls. The insulation shields the product from changes in ambient temperature.
  • Jacketed Tanks- These stainless steel tanks are typically used for procedures that necessitate increased heating, cooling, or thermal stability.
  • Process Tanks- It is used in most manufacturing and industrial operations for mixing, dissolving, or homogenising process components or ingredients.

_The Structure
The Structure

The tank’s structure mostly consists of the following holes: feeding hole, discharging hole, breathing hole, man orifice, cleaning hole, temperature measurement hole, pressure gauge hole, vent nozzle, and so on.

The Durability
The Durability

Stainless steel water tank fabrication is durable but if the water tank will not be taken care of, it may result in some tank leaking or corrosion. On the other hand, if taken care of well, your tank can last for more than 15 years.

_Stainless Steel VS Polyethylene Tank
Stainless Steel VS Polyethylene Tank

Because they are constructed of steel, stainless steel tanks are incredibly sturdy and will not bulge or warp. However, because they are made of metal, they are less impact resistant than a poly tank, which can withstand being hit with a hammer.


The rectangle stainless steel water tank comes with complete accessories, including outlet flange, concrete beam, inlet flange, external ladder, oblique short bar, manhole, C-channel, vertical support, and horizontal tie rod.

Finishes for Rectangular Stainless Steel Water Tank

Mill Finish
Mill Finish:

Secondary milling operations are done to enhance the stainless steel corrosion resistance on the water tanks. The most popular type of mill finish used for stainless steel tanks is No. 2B, No. 2B, as designated by ASTM.

BrushedPolishedGround Finishes
Brushed/Polished/Ground Finishes:

From a mill finish, an additional technique is applied to achieve the desired surface smoothness. Polishing and brushing are done by utilizing fine, abrasive materials bonded to unidirectional cutting belts and discs. Common mechanical finishes are No. 3 and No. 4.


Electropolishing is an electrochemical process that removes or levels microscopic peaks on the surface of the metal. It makes the surface smoother in the order of less than 0.2 µm. Electropolished stainless steel tanks are used where product contamination is an issue, like in the food and pharmaceutical industries.
