5 Common Uses For Dished Ends


Dished ends, also known as tank heads or pressure vessel heads, are essential components in a wide range of industrial applications. These ends are used to close off the ends of cylindrical vessels, ensuring they can withstand internal pressure and maintain structural integrity. At Dished Ends International, we understand the importance of selecting the right type of dished end for each specific application. In this article, we will explore the five most common uses for dished ends, providing real-world examples in Australia and New Zealand to illustrate their versatility and importance.

Dished ends come in various shapes and sizes, each designed to meet the specific requirements of different industries. Whether you are involved in manufacturing, food processing, or chemical production, understanding the common uses for dished ends can help you make informed decisions about your equipment and processes.

#1. Pressure Vessels in Chemical Processing

One of the most common uses for dished ends is in the construction of pressure vessels used in chemical processing. These vessels need to withstand high internal pressures and corrosive materials, making the choice of dished ends crucial. For example, in a recent project with a chemical manufacturer, we supplied ellipsoidal dished ends for their high-pressure reactors. The ellipsoidal shape provided the necessary strength and durability, ensuring safe and efficient operations.

Key Benefits:

  • High Pressure Resistance: Ideal for reactors and storage tanks.
  • Durability: Can withstand harsh chemicals and high temperatures.
  • Example Application: High-pressure chemical reactors.

#2. Food and Beverage Industry

The food and beverage industry also relies heavily on dished ends for various applications, including storage tanks and processing equipment. In this industry, hygiene and safety are paramount. We recently worked with a dairy company that needed torispherical dished ends for their milk storage tanks. The smooth, rounded design of the torispherical ends ensured easy cleaning and maintained the integrity of the product by preventing contamination.

Key Benefits:

  • Hygienic Design: Easy to clean and maintain.
  • Safety: Prevents contamination and ensures product integrity.
  • Example Application: Milk storage tanks in dairy processing.

#3. Oil and Gas Sector

The oil and gas sector uses dished ends in a variety of applications, such as separators, filters, and pressure vessels. These components must endure extreme conditions, including high pressures and corrosive environments. In a project with an oil refinery, we provided torispherical dished ends for their separators. The robust design of the torispherical ends ensured they could withstand the rigorous demands of the oil refining process.

Key Benefits:

  • Robust Construction: Can handle extreme pressures and temperatures.
  • Versatility: Suitable for various equipment in oil and gas processing.
  • Example Application: Separators in oil refineries.

#4. Pharmaceutical Industry

In the pharmaceutical industry, dished ends are used in bioreactors, storage tanks, and pressure vessels. The precision and cleanliness required in this industry demand high-quality dished ends. We recently supplied ellipsoidal dished ends to a pharmaceutical company for their bioreactors. The ellipsoidal shape provided the necessary pressure resistance and ensured the bioreactors met stringent regulatory standards.

Key Benefits:  

  • Precision: Ensures high-quality and consistent production.
  • Regulatory Compliance: Meets industry standards for safety and hygiene.
  • Example Application: Bioreactors in pharmaceutical manufacturing.

#5. Water Treatment Facilities

Water treatment facilities utilize dished ends in their filtration and storage systems. These ends help maintain the structural integrity of tanks and vessels used in water purification processes. In a recent collaboration with a municipal water treatment plant, we provided torispherical dished ends for their filtration tanks. The design of these ends ensured durability and longevity, essential for continuous and reliable water treatment operations.

Key Benefits:

  • Durability: Ensures long-term performance in water treatment systems.
  • Reliability: Maintains structural integrity under constant use.
  • Example Application: Filtration tanks in water treatment plants.
