Benefits of Welded Steel Storage Tanks

Most of our projects are welded steel storage tanks rather than bolted tanks. Welded steel storage tanks have several advantages over bolted steel storage tanks

Some advantages include:

 
 

Reliability

With improved standards over the past few decades, a welded steel storage tank can last many more years. The longevity and durability mean a welded steel storage tank is resistant to corrosion, leaking, and the elements.

 
 
 

Lower cost

Thanks to their reliability, the total cost of owning a welded steel storage tank is lower. With yearly maintenance, repairs (if any!) are usually simple.

 
 
 

Versatility

The visual design possibilities are endless.

 

 

Applications for Stainless Steel Storage Tanks

Stainless steel storage tanks have a variety of uses, but most fall under three main categories: 

 

Chemicals
One of the most popular uses for stainless steel storage tanks is chemical storage as a strong, reliable storage system is required to resist corrosion and protect against easy puncture that could lead to an environmental mess.

Chemical stainless steel storage tanks can take the form of stationary structures set in their foundations or nurse tanks - smaller tanks that are designed to be moved around in the field and that can withstand the rigors of being out in the open and moved on a trailer.

 

Feed
For ranches, feed for livestock is one of the most plentiful materials used on a daily basis. Having a ready supply of feed keeps your cows, pigs, horses, chickens, and goats happy and healthy.

Two key aspects of stainless steel storage tanks for feed are how the tanks will be filled and how they will be unloaded. The right custom metal fabricator will be able to create an ideal product to suit any situation - for example, outfitting a tank with a hopper to ease feed dispersal and fabricating structural steel legs to create a throughway beneath the storage tank so distribution trucks can drive underneath for loading.

 

Water
Irrigation, manufacturing, and fire-protection services require a ready supply of water to hand. For these applications, a conical bottom can be designed for stainless steel storage tanks to ensure quick and complete drainage of liquids.

Potable water can also be stored in stainless steel storage tanks for use in the food and beverage industry.

 

 

 

The Various Grades In Stainless Steel Tank

 

There is a huge variety of stainless steel grades available for handling different chemicals. As such, the performance at both high and low temperatures as well as corrosion resistance, strength, and toughness, differ between grades. The following three grades are commonly used to manufacture stainless steel tanks.

Stainless Steel 304 and 304L
With the exception of steel-forming alloys, stainless steel 304 is made up of 18–20% chromium, 8–11% nickel, and 2% manganese. This type of stainless steel is the most popular since it is less expensive than other grades and offers sufficient corrosion resistance for the majority of uses. It is versatile and suitable for the formation of a wide variety of products due to its austenitic metallurgical structure.

Stainless Steel 316 and 316L
The following elements are found in stainless steel 316:
16–18% chromium
10–14% nickel
2% manganese
2-3% molybdenum
Due to the molybdenum addition, this grade is more corrosion-resistant than stainless steel 304. To combat the increased molybdenum's ability to create ferritic minerals, it contains more nickel.

Duplex Stainless Steel
Duplex stainless steel contains the following elements:
20-28% chromium
2-5% molybdenum
5-8% nickel
This grade of stainless steel has greater corrosion resistance and mechanical strength due to its increased chromium and molybdenum content. Due to its lower nickel content and higher strength for a given thickness, Duplex stainless steel is more affordable to use than 316 since it allows for the use of thinner plates and sheets.

FAQ

 

Q: What are steel tanks used for?

A: Stainless steel tanks are widely used in food, beverage, dairy, medicine, cosmetics, and other manufacturing processes where cleanliness and purity are important. These are also used in industrial plants for storing chemicals and gasses where strong resistance from chemical degradation is required.

Q: What is the difference between a steel tank and a poly tank?

A: Stainless steel tanks are very strong and will not bulge or warp since they are made from steel. Being metal however, they are less impact resistant than a poly tank which will easily withstand being struck with a hammer. A weak point with stainless steel tanks are again in how it has been manufactured.

Q: What is the life of a steel tank?

A: In general, a well-designed and properly maintained welded steel tank can last up to a century, while a bolted steel tank may have a shorter lifespan of 20-30 years, depending on design and maintenance.

Q: Do steel stock tanks rust?

A: Will the tank rust? Galvanized metal does eventually rust, but it usually takes years for this to occur. The number one cause of early rust in a stock tank pool is over treating the water. Chlorine and other pool chemicals tend to eat away at the galvanized coating which leads to rust.

Q: Are steel tanks heavier than aluminum?

A: A standard steel cylinder with a capacity of 80 cubic feet (cf) will weigh around 28 to 30 pounds, while its aluminum counterpart will normally weigh somewhere between 31 to 35 pounds. Size is also an important consideration when it comes to choosing a tank, especially if you're on the smaller or shorter side.

Q: How long does gas last in a steel tank?

A: Three to six months
In general, pure gas begins to degrade and lose its combustibility as a result of oxidation and evaporation in three to six months, if stored in a sealed and labeled metal or plastic container.

Q: How do you maintain a steel water tank?

A: Stainless steel water tanks should be cleaned regularly to remove any dirt, debris, or contaminants that can accumulate over time. Cleaning should be done at least once a year, but more frequent cleaning may be necessary if the tank is exposed to harsh environmental conditions or if there is heavy use.

Q: How do I protect my steel tank from corrosion?

A: 1.Regular and rigorous inspection. ...
2.Recognize early warning signs. ...
3.Clean your equipment regularly. ...
4.Prevent contact with corrosive materials. ...
5.Invest in new protective coatings.

Q: What is the composition of a stainless steel tank?

A: Stainless steel types are created from an alloy (mixture of metals) of defined quantities of iron, chrome, nickel and carbon. Other metals may be added if certain properties are needed. Adding nickel and chrome makes the material easier to work, stronger at high temperatures and more resistant to corrosion.

Q: What grade stainless steel for water tank?

A: Grade 316 stainless steel water tanks are highly resistant to chlorides and non-reactive to other industrial chemicals, forming an impenetrable protective layer to shield the water tank and the water within.
