Stainless steel conical head
Our conical heads are available in a variety of sizes and can be customised to your needs.
The material of the tapered head can be carbon steel, low alloy steel, composite plate, stainless steel, copper, aluminum, titanium and other non-ferrous metals.
In order to reduce the discontinuous stress, the large or small end of the cone shell can adopt a folded edge structure or a partially thickened structure with a circular arc transition.
Under the action of internal pressure on the main part of the conical head cone, the maximum film stress occurs at the large end. At the junction of the cone and the cylinder, due to geometric discontinuity and sudden curvature radius, a large lateral thrust will be generated at this place, which will cause large edge stress and bend easily, so it needs to be strengthened.
The pressure vessel design specifications require: when the half cone angle is greater than 30°, the large end of the cone shell should adopt a folding structure; when the half cone angle is greater than 45°, the small end of the cone shell should adopt a
folding structure, For the big end, the axial bending stress is the main controlling factor and belongs to the secondary stress, so the stress intensity is controlled; for the small end, the stress at the connection between the small end and the cylinder is mainly the average circumferential tensile stress and the average The radial compressive stress belongs to the local membrane stress, so the stress intensity can be controlled.

Q: What's the information should I provide when inquiry?
A: 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.
A: For carbon steel products, we sandblasting descaling product surface. For stainless steel products, we use acid to remove surface oil and impurities.
A: 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.
