Ensuring System Reliability: The Importance of Tanks in Piping System
II JAY SHRI KRISHNA II
Tanks are the unsung heroes of Piping systems. Tanks store lots of liquid; this keeps the flow steady in the pipe. Pipes can get stressed from hot and cold, or if the ground moves. Tanks act like shock absorbers, soaking up that pressure & keeping the pipes safe.
Tanks tirelessly storing and managing essential fluids & can separate liquids like oil & water. But with such a wide variety, choosing the right one requires understanding their design, operation and limitations. Let's delve into the world of Tanks.
Ensuring System Reliability: The Importance of Tanks in Piping System
In Piping systems, which are networks of tubes that transport liquids or gases, Tanks play a critical role in ensuring system reliability. Here's how:

Tanks in Piping System |
1. Storage and Buffering:
Tanks act as Storage Vessels, holding large quantities of fluids. This allows for:
- Continuous operation: Even if the source of the fluid fluctuates or is interrupted, the Tank provides a buffer, ensuring a steady flow downstream in the Piping system. This is crucial for processes that rely on a consistent supply.
- Demand management: Tanks can be used to store excess fluid during periods of low demand and release it during peak periods. This helps to regulate pressure & flow within the Piping system to preventing disruptions.
2. Stress Mitigation:
Tanks help to reduce stress on the Piping system in a few ways:
- Expansion and contraction: Fluctuations in temperature can cause pipes to expand and contract. Tanks can absorb these volume changes, preventing excessive strain on the Piping.
- Settlement and movement: Underground Tanks can experience settling over time, or above-ground Tanks might influence in the wind. Flexible connections between the Tank and piping can accommodate this movement, but properly designed Tanks minimize the stress transferred to the piping itself.
- Surge protection: Sudden changes in flow rate, like when a Pump is turned on or off, can create pressure surges in the piping. Tanks act as a dampener, absorbing these surges and protecting the pipes from potential damage.
3. Process Functionality:
Beyond simple storage, Tanks can be integral parts of specific processes within a Piping system. For instance:
- Separation: In some systems, Tanks are used to separate different fluids based on properties like density. This allows for further processing or purification.
- Mixing: Tanks can be used to mix different fluids together in controlled proportions.
- Chemical reactions: Tanks can provide a controlled environment for chemical reactions to take place.
By incorporating well-designed Tanks into Piping systems, engineers can enhance reliability, optimize performance and safeguard the entire system from potential failures.
Classification of Tanks in Piping System:
Tanks store the essential fluids that keep everything running. But just like there's a variety of fluids to manage, there's also a wide range of Tank types to suit different needs. Some of the most common Tanks in Piping systems classified are:
By Shape:
1. Vertical Tanks: These are the most common type of Tank, with a cylindrical body and a flat or dished bottom. They are ideal for storing large volumes of liquids or gases and are often used in applications like oil and gas storage, chemical processing and water treatment.
2. Horizontal Tanks: These Tanks are elongated cylinders positioned horizontally. They are often used for storing liquids with settling solids or for applications where space is limited. Horizontal Tanks are also commonly used as surge tanks due to their ability to handle changes in flow rate.
3. Spherical Tanks: These Tanks are spherical in shape and can withstand high internal pressures. They are typically used for storing liquefied petroleum gas (LPG) and other highly volatile liquids.
4. Cylindrical Tanks: Strong and simple. These are the classic tall, round Tanks, often used for general liquid storage. Their simple design makes them easy to fabricate and strong.
5. Rectangular Tanks: Space-efficient. Offering a more space-efficient option, Rectangular Tanks are ideal for fitting into tight spaces. Normally, they are used for water storage or industrial processes.
5. Cone or Hopper Tanks: Promotes material flow for granular materials. Shaped like an upside-down cone or pyramid, these Tanks promote material flow from the outlet at the bottom. They are perfect for storing granular materials like, sand or gravel.
By Roof:
1. Fixed Roof Tanks: These Tanks have a permanent roof that is welded or bolted to the tank shell. They are suitable for storing liquids with atmospheric or low-pressure applications, and are often used for water storage, fuel oil storage and ballast water in ships.
2. Floating Roof Tanks: These Tanks have a roof which is floats on the surface of the liquid stored inside. This design minimizes vapor loss and fire risk, making them ideal for storing volatile liquids or liquids with high vapor pressures, such as gasoline and crude oil.
3. Internal Floating Roof Tanks: They contain a floating roof that rests on the liquid surface which is entirely enclosed within the tank's outer shell. This design reduces vapor loss while still allowing access to the Tank interior.
By Pressure:
1. Atmospheric Tanks: These Tanks operate at atmospheric pressure, meaning the pressure inside the tank is equal to the pressure outside. They are typically used for storing liquids with low vapor pressures or for applications where pressure is not a critical factor.
2. Low-Pressure Tanks: These tanks fall under the category of low pressure because they operate close to, but slightly above, ambient atmospheric pressure. They are used for storing liquids or gases that require pressurization for certain applications. Designed to withstand minimal pressure above ambient, these Tanks are often used for atmospheric storage. Fixed roof Tanks typically fall into this category.
3. Pressure Tanks: Built to handle higher pressures, these Tanks are used for storing compressed gases or liquids under pressure. They come in various shapes, including the distinctive spherical "Horton Sphere."
All Tanks are play a crucial role in various applications by performing different functions. By considering these different classification methods, engineers can select the most appropriate Tank type for a specific Piping system application.
Here's a quick breakdown of the different types of Tanks found in Piping systems:
Different Types of Tanks in Piping Systems:
1. Storage Tanks:
These Tanks are used for the long-term storage of liquids or gases. They come in various sizes and shapes, and the material used for their construction depends on the substance being stored. For instance, Steel Tanks are typically used for storing oil and gas products, while Fiberglass Tanks are often used for storing chemicals.
2. Surge Tanks:
These Tanks are designed to accommodate sudden changes in pressure or flow rate within a Piping system. They act as a buffer, absorbing pressure surges & preventing damage to pipes and equipment. Surge Tanks are commonly used in pumping systems, where they help to dampen pressure fluctuations caused by pump startup and shutdown.
3. Mixing Tanks:
As the name suggests, these Tanks are used to mix different fluids or gases together. They are equipped with agitators that help to create a uniform mixture. Mixing Tanks are widely used in various industries, including food processing, pharmaceuticals and chemical manufacturing.
4. Pressure Vessels:
These are Tanks designed to hold fluids or gases at a pressure greater than atmospheric pressure. They are typically made of thick-walled steel and have safety features such as Pressure relief valves to prevent explosions. Pressure vessels are used in various applications, including boilers, compressed air systems, and hydraulic systems.
5. Day Tanks:
These are relatively small Tanks used to store a day's worth of supply of liquid or gas. They are often located near the point of use to ensure a steady flow of material to the process. Day Tanks are commonly used in manufacturing plants to feed liquids or gases to production equipment.
Beyond the Basics:
1. Cryogenic Tanks: These specially designed Tanks store liquefied gases at extremely low temperatures, often requiring double walls for insulation.
2. Process Tanks: Tailored for specific industrial processes, these Tanks might have internal agitators, heating/cooling jackets, or other features to meet the needs of the process.
