Product Features and Benefits

1. Versatile Applications

• Ideal for medium-pressure vessels such as air receivers and liquefied petroleum gas tanks.

• Widely used in industries requiring safe and durable pressure containment solutions.

2. Optimized Design

• Depth of dish equals one-quarter of the head’s internal diameter (ID), ensuring efficient stress distribution.

• The inside height combines the depth of the dish and the straight flange, offering tailored configurations for specific requirements.

3. Economical Solution

• Reduced metal thickness compared to other head types, lowering material costs without compromising structural integrity.

4. Customization

• Manufactured using cold or hot forming techniques to accommodate various dimensions, materials, and thicknesses.

• Every request undergoes a comprehensive feasibility study to ensure the highest quality and suitability.

5. Compliance with Standards

• ASME-compliant 2:1 elliptical flanged and dished heads meet the rigorous requirements for unfired pressure vessels.

Technical Insights

The Ellipsoidal Head 2:1 is characterized by its unique geometry, consisting of a rotating ellipsoidal sphere combined with a cylindrical straight section. This design provides optimal strength and reduces material thickness requirements, making it an efficient and reliable choice for medium-pressure applications. The dish radius is approximately 90% of the diameter, while the knuckle radius is about 17%, ensuring balanced stress distribution and robust structural integrity.
