Custom Tank Heads & Pressure Vessel Heads

Rounded end caps that are welded or fastened to the ends of cylindrically shaped pressure vessels, typically made of metal such as steel or aluminum, tank heads are used to close and seal the ends of a tank, providing a pressure vessel with a secure and stable enclosure.

Komax Systems' ASME tank heads can be used in a wide range of applications, such as in the chemical and petrochemical industries, oil and gas storage, water treatment, as well as in food and beverage processing.

The utility of our tank heads lies in their ability to provide a safe and reliable closure for tanks and pressure vessels that are subjected to high pressures or vacuums. Our tank heads are designed and manufactured to meet strict quality and safety standards, including ASME codes and regulations, and are tested to ensure they can withstand the pressures and stresses they are subjected to.

Our Product FAQs

We are able to manufacture tank heads out of almost any material! Just provide us with the specification you are requiring and we will be sure to produce your product to your desired specs! Because some materials take pressure differently and are less sturdy when it comes to the flanging process, we must quote on a best-effort basis for some of the more unique materials. Get in touch with our engineers today to get a quote on your tank head project!
In our shop we are able to produce tank heads with an OD ranging from 24" - 120".
Tank heads are the end caps on cylindrically-shaped pressure vessels. They can also be used on distillation towers, reactors, drive cylinders, storage tanks, and more. Our tank heads are manufactured according to ASME specs and certifications to ensure top quality during manufacturing.
