What Are Tank Heads and Where Are They Used?

Tank heads, also called dished ends or end caps, are concave metal discs that seal the ends of cylindrical tanks and pressure vessels across a wide range of industries. They are precisely engineered to withstand significant internal pressure and weight loads that tanks and vessels endure during operation.

The curvature of the tank head is designed to provide enhanced strength and minimize stress. Based on the specific tank dimensions, different curvatures can be used, such as torispherical, ellipsoidal, toriconical, and hemispherical. The thickness of the metal disc and concave depth are calculated based on the capacity and pressure requirements.

Common applications where tank heads play a critical role include:

  • Storage tanks holding crude oil, natural gas, chemicals, and other products. Tank heads seal these large cylindrical storage tanks safely.
  • Pressurized tanker trucks and railcars transporting products like propane, ammonia, chlorine, and other industrial chemicals. Tank heads enable safely transporting chemicals at higher pressures.
  • Process vessels and tanks in oil refining, natural gas processing, chemical and pharmaceutical production, food and beverage, water treatment, and other industries. The heads handle internal pressure safely.
  • Boilers, condensers, heat exchangers, and other power generation equipment. Tank heads are used extensively in thermal power plants.
  • Pulp and paper processing equipment like digesters and tanks need extremely durable heads.
  • Mining and mineral processing vessels use heads customized for corrosion resistance.

Based on the specific temperature, pressure, and chemical exposure conditions, tank heads can be manufactured from carbon steel, stainless steel, aluminum, nickel alloys, titanium, zirconium, Hastelloy, Monel, and several other exotic metals and alloys.


Choosing the Right Tank Head Manufacturer

With tank heads being such a vital component affecting safety and performance, choosing the right supplier is an important decision. Here are key factors to consider when selecting tank head manufacturers:

  • Quality and Testing Standards

Tank heads require extensive quality checks, mechanical testing, non-destructive testing, and metallographic testing to ensure they meet stringent industry standards like ASME Section VIII. Reputable manufacturers have rigorous inspection, testing, and documentation processes in place for raw materials, machining, welding, and final products.

  • Custom Design and Engineering

Every tank and application requires tank heads to be designed with custom dimensions, metal thickness, and other specifications tailored to the exact operating conditions. Choose a manufacturer with proven in-house engineering expertise in customized tank head design to match your specific requirements.

  • Material Options and Certifications

Based on your particular operating environment, you may need heads made from stainless steel, Incoloy, Hastelloy, titanium, or other alloys to withstand corrosion, temperature, and pressure. Ensure your supplier is experienced in those exotic metals and can provide material certifications.

  • Range of Manufacturing Processes and Capabilities

The optimal tank head manufacturing method depends on factors like diameter, metal thickness, quantities, lead times, and cost. Look for suppliers with expertise in multiple processes like metal forming, spinning, pressing, welding, heat treatment, and precision machining.

  • Reliability and Quality Control

You need a supplier who can consistently deliver high-quality tank heads on time to your specifications. Carefully assess their quality control standards, on-time delivery rates, responsiveness, and feedback from past customers.


Common Challenges and Solutions in Working with Tank Head Manufacturers

  • Obtaining Heads that Perfectly Match Your Specifications

To avoid back-and-forth, work closely with the engineering team from the design phase itself and conduct thorough design reviews before production. Provide comprehensive specifications and have open technical conversations about any needed customizations.

  • Finding the Right Balance of Quality and Cost

Partner with a manufacturer that has a wide range of production capabilities so you can optimize for both cost and quality. Choose a process fit for your needs. Lower costs may sometimes compromise quality and safety.

  • Ensuring Consistent On-Time Delivery

Thoroughly vet potential suppliers on their capacity utilization, internal planning and logistics, and shipment capabilities to ensure consistent on-time delivery. Build necessary time buffers into your project schedules, as some delays do happen.

  • Getting After-Sales Support

Choose tank head manufacturers focused on building long-term partnerships with customers, not just one-time transactions. Ask about after-sales support like installation guidance, repair services, ongoing maintenance support, and feedback channels.

  • Lack of Transparency and Communication

Set clear expectations about progress reporting processes upfront. Voice any concerns proactively. Keep communication channels open in both directions throughout the design, production, shipment, and after-sales phases.


What to Look for in a Tank Head Manufacturing Partner

With tank heads being such critical components affecting the safety and performance of your systems, choosing the right supplier is very important. Here are good practices to follow:

  • Do thorough due diligence on their engineering expertise, production capabilities, quality certifications, and industry reputation.
  • Understand their experience in manufacturing heads for your particular industry and operating conditions.
  • Review case studies and testimonials from past clients, especially those similar to you.
  • Have detailed discussions with engineers on your specifications and expectations. Resolve all concerns proactively.
  • Monitor production quality and progress closely through pre-agreed reporting processes.
  • Look for manufacturers focused on long-term partnerships and after-sales support, not just one-time transactions.
