Dished-only ends, also known as dish-only heads or dished-only tank heads, are essential components across various industries. These uniquely crafted elements provide structural integrity and secure containment in pressure vessels, truck tanks, silos, and more. At Haipei Industry, we manufacture high-quality dished-only ends, ensuring compliance with industry standards while meeting our clients' specific needs.

How Are Dished-Only Ends Made?

Dished-only ends undergo a meticulous production process to ensure durability and precision. The manufacturing involves either hot pressing for standard sizes or progressive cold pressing for non-standard dimensions. The key steps include:

  • Material Selection: Choosing the appropriate material based on the application, including carbon steel, stainless steel, and specialty alloys.

  • Cutting and Sizing: Metal discs are cut from large sheets according to the required specifications.

  • Pressing and Shaping: The discs are pressed into a concave shape, forming the signature curvature of dished-only ends.

  • Quality Assurance: Rigorous testing ensures every piece meets industry standards and project requirements.

At Haipei Industry, we offer dished-only ends ranging from 89mm to 13 meters in diameter, with material thicknesses between 2mm and 400mm. Our team collaborates closely with clients to deliver components that align with their specifications.

Dished-Only Ends: Common Applications

Dished-only ends play a crucial role in industries where secure containment and structural strength are vital. Their applications include:

  • Storage Tanks: Used for liquid containment, such as fuel and chemical storage tanks.

  • Compartmentalization: Internally dividing tanks to create multiple compartments.

  • Industrial and Construction Uses: Supporting transportation, power, offshore, food and beverage, and other sectors.

Haipei Industry supplies dished-only ends to small and large-scale businesses, ensuring durability and performance across multiple industries.

Torispherical Head (also called torispherical dish end or torispherical ends) is widely applied for pressure tanks to storage liquids and gasses. The torispherical head consists of a spherical surface, a cylindrical edge of a certain height, and a transition section connecting the above two parts with a radius of curvature smaller than the radius of the sphere. Our asme torispherical head can be made with carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. The stress distribution of torispherical dish head is not as uniform as elliptical head, but the manufacturing processing of the torispherical head is easier. However, torispherical dish end is the better option when the elliptical head of the mold processing is difficult. We can fabricate torispherical ends in most popular sizes and thicknesses.
