Asme air tank

Types of ASME air tanks

An air compressor stores air in an ASME air tank/compressor receiver. The tank's primary job is to store compressed air, which can then be utilized right away or stored for later usage. In some cases, an ASME air receiver also helps control the amount of air that a compressor generates and may even assist in regulating the working pressure of a tool or equipment.

The following types of ASME air tanks are available:

• Vertical air tanks

  Vertical air tanks/compressor receivers are cylindrical containers that are mounted on a stand perpendicular to the ground. This type of tank is ideal when floor space is limited but height can be taken into consideration. Vertical air tanks typically have the same components as horizontal tanks; however, the fittings may vary due to the vertical position of the tank.

• Horizontal air tanks

  Horizontal air tanks/compressor receivers are cylindrical containers that lay parallel to the ground. This type of tank is ideal when a stable base is needed, or when multiple tanks need to be placed side by side. Like vertical tanks, horizontal air tanks typically have the same components as horizontal tanks; however, the fittings may vary due to the horizontal position of the tank.

• Skid-mounted air tanks

  Skid-mounted air tanks/ASME air receiver Compressed Air Storage Tanks are portable compressed air storage tanks that are mounted on a skid or base for easy transportation and placement. These tanks are ideal when compressed air needs to be stored in different locations or when temporary storage is required.

Note that aside from these types that focus more on how the ASME air tank is positioned or mounted, there are also distinct tanks based on functionality:

• ASME separation tanks

  A separation tank is a pressure vessel that separates the gas and liquid phases. Compression separation tanks are often used to remove water or other liquids from compressed air or gases. They operate on the basis of gravity or centrifugal force, which allow for the settling of liquid droplets at the bottom of the tank while dry air or gas continues to flow out.

• ASME custom air tanks

  A custom air tank allows businesses to choose their size, shape, and other features to better suit their requirements. They are often used in industrial settings where standard-sized air tanks will not be adequate for a company's needs. Businesses can partner with manufacturers to design and create a custom air tank that fits their specifications.

Specifications and maintenance of ASME air tanks

The specifications of ASME-compliant air tanks will usually be for the size. Capacities range from 1 to 20,000 gallons. Larger tanks can be from 500 to 20,000 gallons, and multiple tanks can be connected to provide the pressure and volume needed by the air compressor system. Standpipes and reservoirs are examples of large ASME air tanks that store compressed air, usually for a dry process application. Connecting the tank to the air compressor with a larger diameter pipe will reduce the pressure loss due to the increased flow of air.

The tank material is typically carbon steel, but stainless and aluminum steel options are also available. Tanks with a greater tensile strength may use aluminum alloys, such as 6061, for a lighter-weight tank or one that can withstand higher pressures. ASME air tanks, valves, fittings, and flanges ensure leakage and minimize any defects. The maximum pressure design is generally 125 PSI but can be as high as 3,000 PSI.

The dimensions include the height and diameter. For example, a 500-gallon tank's specifications may list it as being 6'1" tall with a diameter of 4'5". An example of larger ASME air tanks is a 2000-gallon tank that is 10 feet tall with a diameter of 39 inches. Whether vertical or horizontal tanks are used will depend on the available floor space and the requirements of the air compression system.

Maintenance of ASME air tanks is essential to remove any moisture in the compressed air and rust from the inside:

• The drain valve must inspect annually and tested per the schedule outlined in the QAI Standard for Periodic Inspections..
• The minimum requirement of one manual drain of the tank every week or dry process application every 3 months to remove condensation from the tank
• Any repairs to the tank will corrode are vapors of hydrogen around welds and flaws. The same area will be vulnerable to injury because stress occurs when the tank is under pressure. A qualified engineer or a certified, professional pipeline inspector should carry out the repair.

Any corrosion or damage to the tank, fittings, or valves, especially where the air comes out, will hamper the regular function of the air compressor. Regular inspection will result in a secure supply of compressed air at the required pressure.

How to choose ASME air tanks

Here are some helpful tips for business buyers when selecting industrial air tanks or pressure vessels for commercial applications.

• Understand the primary function

  Determine the main purpose of the air tank. Will it serve as a storage vessel, a separator, a reactor, or an air compressor tank? Knowing the primary function will help to make precise specifications.

• Consider pressure and volume requirements

  The air tank's pressure rating and volume must match the needs of the gas generation system. It must be powerful enough to handle the working pressure of the process. However, avoid excessive pressure that could lead to higher costs and complex safety regulations.

• Check gas-tightness demands

  Choose an air tank with a design that meets the required level of gas-tightness. For example, a frequent-opening vessel will not need to be fully gas-tight, while a separator must have a perfect seal to function correctly.

• Identify heat-transfer needs

  Consider whether the process requires heat transfer. If yes, select an air tank with the appropriate heat-exchanging components. Choose an air tank without heat exchangers if the system does not require any heat transfer.

• Choose the suitable construction material

  Select a construction material for the air tank that matches the system's needs and environmental conditions. Options include stainless steel, carbon steel, or other alloys that offer resistance to corrosion, high temperatures, or other harmful conditions.

• Evaluate available fabrication techniques

  Choosing the correct fabrication method is critical to the air tank's quality, performance, and lifespan. Consider the advantages and disadvantages of each method and select the most suitable for the given application requirement and commercial situation.
