Hot Pressed Dished Heads

Product Description

Ellipsoidal head is also called elliptical head or elliptical dish end. The shape of this ellipsoidal head is more economical, because the height of the head is just a fraction of the diameter. The elliptical dish end radius varies between the major and minor axis usually with the ratio is 2:1. The elliptical tank head is the economical solution for medium pressure tanks due to the reduced metal thickness requirement.

Hot pressed dished heads, also known as hot formed dished heads, are specialized components used in the construction of pressure vessels and tanks. In the fabrication of hot pressed dished heads, a metal plate is heated to an appropriate temperature and then pressed against a mold or die with the desired curvature. This method ensures a precise and uniform shape, resulting in heads that offer improved structural integrity and stress distribution compared to other shapes.Vessel dished head is an indispensable and important part of pressure vessel equipment in many industries from petrochemical, atomic energy to food and pharmaceutical.

The vessel dished head is the end cap on the pressure vessel and is a major pressure-bearing part of the pressure vessel. The role played is that of sealing. Firstly, it is made into the upper and lower bottom of the tank-shaped pressure vessel, secondly, when the pipe reaches the head and is not ready to extend forward, a head is used to seal the pipe in the form of welding. Products with similar functions as heads are blind plates and pipe caps, but these two products can be dismantled. But these two products can be disassembled, whereas a head cannot be disassembled after it has been welded. The fittings used with them are pressure vessels, pipes, flanges, elbows, tees, crosses and other products.

The quality of the vessel dished ends are directly related to the long-term safe and reliable operation of the pressure vessel.

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.

FAQ

ASME VIII. Div 1 Semi Elliptical Heads 2:1 with PDR Report 2:1 Ellipsoidal Dished Heads comply with UG-81 UCS-79

Q: What’s the information should I provide when inquiry?

A: Thanks for your question. If you have drawings, we will be entirely in accordance with production drawings . If you do not have the drawing, you can tell me the product data. There are several important data, such as material, type of head( We have elliptical head, hemispherical head, dished head, flat head, etc. ),diameter, thickness, special tolerances or requirements. We can do the drawings according to your requirements, and you confirm that the final product drawings.

Q: what are surface treatment of the product?

A:Thanks for your question. For carbon steel products, we sandblasting descaling product surface. For stainless steel products, we use acid to remove surface oil and impurities.

Q: How do you ensure the quality of products?

A: Thanks for your question.Our production staff is trained through national quality department, and obtain the corresponding certificate, with years of production and design experience. Weld must undergo X-ray inspection to ensure that no defects.

Q: Can you help us matching related products?

A: Thanks for your question. Our company also is surrounded by a lot of ancillary businesses, such as flanges, boiler, oil refining equipment, etc. We can help you matching the highest quality products with the lowest prices .
