ASME Code Dished Heads, Hot Pressed Heads for Pressure Vessels

The elliptical head is also known as the elliptical head. The elliptical head is a head composed of two parts: a rotating elliptical sphere and a cylindrical straight section. The elliptical head with the ratio of the major axis to the minor axis of the revolving elliptical sphere generatrix is 2.0, and is customarily called the standard elliptical head.

The mechanical properties of the elliptical head are second only to the hemispherical head, but better than the dish-shaped head. Since the depth of the elliptical head is between the hemispherical and the dish-shaped head, the requirements for stamping equipment and molds and the manufacturing difficulty are also between the two, that is, it is easier than the hemispherical head and more difficult than the dish-shaped head. In recent years, the use of spinning technology has brought convenience to the manufacture of large-diameter elliptical heads. Oval heads are widely used in medium and low pressure vessels due to their better overall performance.

FAQ:

1. What’s the information should I provide when inquiry?

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.

2. what are surface treatment of the product?

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.

3. How do you ensure the quality of products?

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.

4. Can you help us matching related products?

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.
