Product Description Unveiling the Concept of Pressure Vessel Heads :A pressure vessel head, the essential terminus of a pressure vessel's cylindrical section or shell, is pivotal for securing the vessel. Known by a plethora of terms—Dish Ends, Formed Heads, End Closure, End Caps, Vessel Ends, and Vessel Caps—the most prevalent moniker remains 'Dish ends.' These heads are the unsung heroes in the realm of pressure-containing equipment.Exploring the Diverse Types of Pressure Vessel Heads :Among the myriad of pressure vessel heads, four principal types of Dish ends stand out, forming the backbone of pressure vessel fabrication.Flat HeadsEllipsoidal HeadsTorispherical Heads or Flange and Dished HeadsHemispherical HeadsFlat Heads :The Flat Head is the most straightforward design among pressure vessel heads, though it's less frequently favored due to its limited pressure endurance. Its limited radial section offers a constrained area for pressure distribution, concentrating stress on the flat surface and making it less cost-effective.Flat HeadsKey terms associated with Flat Heads include Flat Head Inside Diameter (ID), Knuckle Radius (R), Dish End Total Height (H), and Straight Face (SF). A comprehensive Flat Head Drawing provides a visual representation of these features.Ellipsoidal Heads :Revered as the most widely utilized type, Ellipsoidal Heads boast an expansive radial section for optimal pressure distribution, offering superior pressure resistance. Their design thickness aligns closely with the shell, rendering them highly economical. The preferred configuration is a 2:1 Ellipsoidal Section, balancing efficiency with performance.2:1 Ellipsoidal HeadsIn the realm of 2:1 Ellipsoidal Heads, crucial terms include Inside Diameter (ID), Crown Radius (C.R), Knuckle Radius (K.R), Dish End Total Height (H), and Straight Face (SF). The detailed Drawing Representation further elucidates these aspects. Despite requiring more shaping time than Flat or Torispherical Heads, they remain the epitome of economic pressure vessel heads.Torispherical Heads or Flange and Dished Heads :Renowned for their utility, these heads provide a generous radial section for effective pressure distribution. Despite offering less pressure resistance than ellipsoidal variants, their reduced forming time enhances their popularity.In identical design conditions, the thickness of Torispherical Heads approaches 1.77 times that of the Shell, balancing Design Pressure and Temperature considerations.Torispherical HeadsVital terms in the Torispherical Heads lexicon include Inside Diameter (ID), Crown Radius (C.R), Knuckle Radius (K.R), Dish End Total Height (H), and Straight Face (SF). The Torispherical Head Drawing Representation conveys these elements vividly.Their simpler formation process compared to ellipsoidal types enhances their appeal, earning them the alternate title of Flange and Dished Heads.Hemispherical Heads:This configuration reigns supreme in radial section availability, offering unparalleled pressure distribution capacity. For the same design criteria, the thickness of Hemispherical Heads is nearly half that of the shell, optimizing material efficiency.Though they demand the most extended forming time, Hemispherical Heads stand out as the most economical choice among all head types.Hemispherical HeadsWhen discussing Hemi Heads, several critical terms come into play, including Inside Diameter (ID), Crown Radius (R), Dish End Total Height (H), and Straight Face (SF). The selection of Dish Ends is primarily determined by the design criteria and their suitability for specific pressure vessels.There are four fundamental types of dish ends commonly employed in the fabrication of pressure vessels. The majority of dish end terminology is derived from standard relationships with their inside diameter. From a fabrication perspective, it is crucial to calculate various terms, including Dish End Terms, Blank Diameter, Weight, Surface Area, and Volume. These calculations are integral to the production of high-quality dish ends.Below are some of the exceptional products that we at LEGO METAL (QINGDAO) LTD proudly manufacture:
