Pressure Vessel Heads are critical components in industrial equipment. These are the closures or capping elements that seal the ends of a pressure vessel's cylindrical section or shell. Commonly referred to as Dish Ends, these heads ensure safety and efficacy in operations. Other popular terminologies include Formed Heads, End Closures, End Caps, Vessel Ends, and Vessel Caps, but 'Dish Ends' remains the prevalent term.
Delve into the world of pressure vessel fabrication with four fundamental types of heads, commonly known as Dish Ends, each offering unique benefits for specific applications.
Flat Heads are the most basic form of pressure vessel heads, yet they offer limited utility due to their lower pressure tolerance. Their design features a minimal radial section for pressure distribution, leading to maximum stress on the flat section. This makes them a less economical option compared to other head types.
When discussing Flat Heads, familiarity with terms like Inside Diameter (ID), Knuckle Radius (R), Dish End Total Height (H), and Straight Face (SF) is essential. The general drawing representation provides a clear view of these aspects.
Ellipsoidal Heads are the preferred choice in pressure vessel applications, providing a broad radial section for even pressure distribution. They stand out for their exceptional pressure tolerance, making them the most economical option. Typically, the thickness of these heads aligns with the shell thickness, particularly in the 2:1 Ellipsoidal Section configuration.
Key terms for 2:1 Ellipsoidal Heads include Inside Diameter (ID), Crown Radius (C.R), Knuckle Radius (K.R), Dish End Total Height (H), and Straight Face (SF). Despite requiring more forming time than Flat and Torispherical Heads, their economical advantage makes them a top choice.
Torispherical Heads are widely used due to their efficient pressure distribution and quicker forming time compared to ellipsoidal heads. While slightly less economical, their ease of fabrication makes them a popular choice in many applications.
For similar design conditions, the thickness of Torispherical Heads is approximately 1.77 times the shell thickness, accommodating the same design pressure and temperature.
Familiarize yourself with terms like Inside Diameter (ID), Crown Radius (C.R), Knuckle Radius (K.R), Dish End Total Height (H), and Straight Face (SF). The simplicity of forming these heads, also known as Flange and Dished Heads, makes them a favored option.
The ease of forming Torispherical Heads, relative to their Ellipsoidal counterparts, enhances their appeal. This Head, also termed Flange and Dished Head, is prized for its simplicity.
Hemispherical Heads offer unmatched radial sections for unparalleled pressure distribution. For the same design conditions, the thickness of these heads is roughly half that of the shell, making them the most robust choice for high-pressure applications.
The most economical of all head types, our selection offers unparalleled value, though it does demand the longest formation time. Invest in efficiency and quality with our heads.
In the world of hemi heads, the commonly used terminology revolves around Inside Diameter (ID), Crown Radius (R), Dish End Total Height (H), and Straight Face (SF). The choice of dish ends is crucial and is governed by design conditions alongside their suitability for pressure vessel heads.
These are the four fundamental types of dish ends employed in the fabrication of pressure vessels. Most terms related to dish ends are derived using standard relationships with their inside diameter. From a fabrication perspective, it is essential to compute various parameters. These include dish end terms, blank diameter, weight, surface area, and volume calculations, all pivotal for the precise fabrication of dish ends.
