ASME Dish Ends For Pressure Vessel Stainless Steel End Caps

Description

Dished head, also known as hemming with spherical head. Consists of a sphere, a cylinder of a straight edge height and radius of curvature of connecting these two portions is substantially less than the radius of the spherical part of the composition of the transition. Dished head as a continuous surface, at the junction of three parts, the radius of curvature of the warp mutations, due to changes in curvature, therefore there is bending stress. Bending stress and tensile stress superposition result, the stress this part protruding from the rest. Compared with oval head, uniform stress distribution which is better, but easier than working, which is not ideal in engineering use. But when the head of the oval mold is difficult, then replaced with a dished head.

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.
