Torispherical Head Dished Heads Tank Heads

Torispherical Head Dished Heads Tank Heads

Stainless steel dished head is a kind of product used to seal stainless steel pipeline. It is a kind of product that is used for container after the pipe reaches the dished head or two vessel heads are welded on the two ends of a section of round pipe. It has the characteristics of non-rusting, anti-abrasion, non-scaling, reducing oscillation and noise.

Stainless steel ellipsoidal head is made of stainless steel 304, 316L, 321, etc. The head is composed of two parts: rotating ellipsoidal spherical surface and cylindrical straight section. The function of the straight section is to avoid the sudden change of radius of curvature in the warp direction at the weld joint between the head and the cylinder, so as to improve the force condition of the weld. The end cover of the pressure vessel is the head plate, is one of the main pressure parts. The quality of the dished head is directly related to the long-term safe operation of pressure vessel.

Application

The Dished Head is the petroleum chemical industry, atomic energy food pharmaceutical industries pressure vessel equipment in an important and indispensable component.

Application scope of stainless steel head: petroleum, electronics, heating, chemical, pharmaceutical, sewage treatment, light textile, food, machinery, construction, nuclear power, aerospace, pressure vessel, military and other industries.

Hemispherical Head (also called hemispherical tank heads or hemispherical dish ends) is widely applied to make pressure tanks to storage liquids and gasses. Our asme hemispherical head is often made with carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. Hemispherical is the ideal shape for development of hemispherical dish end, because the pressure in the vessel is divided equally across the surface of the head. The radius (Ri) of the head equals the radius of the cylindrical part of the vessel. This type of hemispherical tank heads or hemispherical dish ends are made in most popular sizes and thicknesses.

Ellipsoidal head (also called elliptical head or elliptical dish end) is usually made with Carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. 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.

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.

Conical Head (also called the tapered tank head) is widely used for vessel bottom or cover plates. With the shape of concentric cone, the toriconical head consists of a large end cone and a small end. Cone and large end of the connection, due to geometric discontinuity, the radius of curvature of the mutation, so there will be a large lateral thrust, causing a large edge stress, prone to bending, it is necessary to strengthen.the tapered head The cone head type is divided into CHA (30), CHA (45), CHA (60) by half angle.

FAQ

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.
