Used tank

Types of used tanks

A used tank is an industrial container with a significant capacity, primarily established to store products. Usually, they can classify into two categories: vertical tanks that are erected upward, occupying little ground area, and horizontal tanks, which are put on flat surfaces, occupying more floor space but lesser height. Both types perform similar functions but are suitable for different industries and purposes. Moreover, tanks can also be seamle or seamed. The seamle tanks are produced without any seams and hence are more durable, whereas the haems tanks can be produced in any size, including large sizes. A stainless steel used tank can come in any shape depending on its purpose- square, round, oval, or even rhomboid, but all kinds of stainless steel tanks are easy to clean.

Typically, tanks are manufactured from materials like carbon steel, stainless steel, or fiberglass, each suited for specific storage needs. For instance, food-grade stainless steel is used for tanks that store consumable liquids, like milk or beer, because this particular material is nontoxic. Stainless steel also offers durability, resistance to corrosion, and an extended lifespan. Stainless steel tanks are often chosen for their easy maintenance and cleaning.

Used tanks can be further categorized based on their types of bottoms and tops.

• Tank with flat bottom and flat top

This type of tank has a flat bottom and a flat top, which makes it easier to stack and transport. It is often used for storage and distribution of solid materials.

• Tank with flat bottom and domed top

This kind of tank has a flat bottom and a dome top, which enables it to hold liquids and gases. It is usually utilized in the chemical and petroleum industries.

• Tank with dome bottom and dome top

The dome bottom and dome top tank is distinguished by its dome-shaped ends. It is applicable for storage of high-pressure gases and liquids. The tank with dome bottom and dome top is suitable for harsh environments and offers dependable safety protection.

• Tank with cone bottom and flat top

This kind of tank features a conical bottoms and flat tops. It has good drainage performance and is usually used in food processing and wastewater treatment.

Specifications and Maintenance

• Industry

  Food Grade: Used stainless steel tanks for the food industry must meet specific food standards to ensure that they do not contaminate consumables. This often involves having surfaces that are easy to clean and not allowing bacteria to harbor in crevices. Common food grade tanks include pasteurization tanks, fermenter tanks, and cheese aging tanks.

• Chemical

  Chemical Grade: Used stainless steel tanks for chemicals need to be compatible with the chemical's properties. Some chemicals can be corrosive, and others might react with different metals. Assessing the tank's integrity and ensuring that it's built from materials that can handle the chemicals, is crucial. Common chemical grade tanks include acid storage tanks, ammonium storage tanks, and liquid fertilizer tanks.

• Capacity

  Capacity: Used stainless steel tanks can hold anything from a few gallons to thousands of gallons. The tank's size should match the needs of the business. A tank that's too small might frequently run out of stored material, while one that's too big could be costly to maintain and operate.

• Pressure Rating

  Used stainless steel tanks that are designed to hold materials under pressure need to have a pressure rating that ensures safety. Pressure tanks are built to withstand higher pressures, and they have features like thicker walls and safety valves.

Tank cleaning is an important part of used tanks' maintenance. Cleaning ensures that residues or contaminants do not affect the quality of products. Also, regular tank cleaning helps to remove algae or mold growth that may clog pumps or cause equipment damage.

The first step in the used tank cleaning process is to drain all liquids from the tank. Next, verify that there are no leaks or cracks in the tank. Look for bulkhead fittings or valves that are worn out. Repair any leaks before proceeding to clean the tank.

After this, prepare the cleaning solution based on the products that were hosed in the tank. For food-grade tanks, citric acid or a sodium hydroxide solution is commonly used. Chemical tanks may use hydrochloric acid or other commercially known tank cleaning products.

Use high-pressure water and spray the solution around the interior of the tank. Make sure to cover all tank surfaces thoroughly. The solution breaks down residue and contaminants. After about 15 minutes, use high-pressure water again to rinse the cleaning solution from the tank.

Finally, allow the tanks to dry properly before storing them. If there are any leaks or issues with fittings or valves, make sure to repair them again. Document the entire tank cleaning process. Adhere to all safety standards when handling cleaning solutions.

Scenarios of used tanks

Tanks are incredible pieces of equipment that are especially useful when dealing with large quantities of liquid. They help businesses in several industries, such as construction, food, and chemical, to work more efficiently.

Here are some ways most industries use tanks to improve their workflow:

• Industries with used mixing tanks: Mixing tanks are versatile and applicable across several industries. For instance, in the pharmaceutical industry, mixing tanks with agitators help create solutions, suspensions, ointments, emulsions, syrups, and other formulations. When combining chemicals, paint, or coatings in the chemical industry, mixing tanks can also be helpful. Additionally, mixing tanks work well in the food and beverage sector. They are useful when producing anything from baked goods to dairy items.
• Used storage tanks for liquids, gases, and solids: Storage tanks can make life easier in many industries. For example, in construction, they hold things like water, fuel, and even waste. Factories that deal with chemicals often use them to store raw materials, products, and even things like wastewater. Agriculture also benefits from storage tanks; they tank anything from farm equipment, dairy products, liquid fertilizers, and pesticides. In energy, storage tanks hold fuels like oil, gas, and even renewable energy sources like biodiesel. Transportation industries use storage tankers to store or transport anything from food or beverage products to chemicals in the supply chain.
• Used pressure tanks for storing compressed gases: Pressure tanks work well in the energy sector for holding natural gas, carbon dioxide, and even hydrogen. Gas compressors often use pressure tanks to compress gases, leading to pressure changes that improve product quality. Diving industries also benefit from pressure tanks. They store divers and underwater personnel for underwater activities, training, or research purposes. Water supply and treatment facilities also use pressure tanks for holding and regulating the flow of water in distribution systems.

How to choose used tanks

Used vertical tanks for sale can help reduce operational expenses, but one must be careful when selecting them. Here are a few factors to inspect before buying a second-hand tank:

• Deep Cleaning and Sanitation

  Prior to purchasing a used tank, it's crucial to gather information regarding its previous usage and the cleaning procedure it underwent post-usage. Certain tanks might have been used to store items challenging to clean thoroughly. For instance, tanks previously utilized for storage in the food industry could have harbored stubborn flavors or residues from natural products, making them nearly impossible to purify entirely. Notwithstanding the potential cost advantages, investing in a tank with lingering contaminations could jeopardize product integrity and consumer safety.

• Quality of Previous Product

  Used tanks' previous contents can significantly affect their current state. For instance, tanks that held corrosive chemicals may have sustained undetectable damage, compromising their integrity. Such tanks should be avoided, regardless of their low cost. Even small, invisible flaws can lead to catastrophic failures later on.

• Presence of Leaks and Damage

  A visual inspection for leaks and damage should always be prioritized. Equipment shopping should never resemble an aesthetic selection. Buyers should prioritize purchasing functioning equipment whose value is not severely diminished by its external appearance. Even if a tank appears battered and bruised, its inner workings could still be essential and highly useful.

• Reusability of Parts

  Consider the salvageable components of retired tanks, such as valves and gaskets, which may still possess a serviceable lifespan. These parts could offer valuable solutions to running and maintaining operational tanks. Opting for a vintage tank over a new one might prove more economical in the long run, as some used tanks possess interchangeable parts.
