Dished Ends

Dished Ends

Pressure vessels are subjected to a lot of tensions and pressures, which require them to be sealed to prevent leaks and spills. Dished Ends are end caps, which are welded directly on the main body of a pressure vessel. The cap starts as a flat disc shape making use of the right material grade to meet the correct characteristics of the module. The Stainless Steel Dished Ends possess superior strength and excellent mechanical properties. These components have excellent resistance against all forms of corrosion and erosion in different stress-induced environments. Pressure Vessel Dished Ends are designed to suffice in high pressure and temperature systems. These ends possess excellent hardness and exhibit enhanced tolerances across various systems. We belong to a unique category of Dish End Manufacturers In India who subject our products to vigorous testing and screening to eradicate any flaws and weaknesses within the system. Our goal is to supply the best products, which are available at the most feasible rates.

Manufacturer & exporter of Pressure Vessel Dished Ends, Tank Dish End, and Purdies Ellipsoidal Head in India

The modules in this range can be produced either as torispherical, ellipsoidal, and hemispherical heads. The Din 28011 Torispherical Heads have a shape similar to an ellipse and are used in closing the ends in a variety of cylindrical pressure vessels. These heads are cheap and can be fabricated with ease. An Ellipsoidal Dish is preferred in applications where the pressure constraint on the component is above 10 bar. These components have heads, which are deeper in comparison to torispherical components. The Carbon Steel Ellipsoidal Dish contains a high concentration of carbon, giving it enhanced strength. These products are moderately ductile and show high resistance to wear.

Tank Dished Ends are highly versatile and used in oil and gas, petrochemical, fertilizer, water lines, food processing. The test certificates and warranties are shipped with the products. The Purdies Dished Head is very reliable and has a long service life. These components can be custom designed as per your requirements in specified shapes and dimensions. Our institution is the Dished Ends Manufacturers In India who makes use of the latest technology and the best raw materials while producing the best products.

Pressure Vessel Dished Ends Types

Ellipsoidal Heads

Ellipsoidal Heads

They have more extensive Radial segment for pressure circulation. It is likewise called as 2:1 curved head. The Head stature is a fourth of the width. The sweep of it might shift from minor to significant pivot. It oppose more pressing factor as contrast with different heads.


Hemipherical Heads

Hemipherical Heads

The state of head is circle, in light of the fact that the pressing factor in the vessel is partitioned similarly across the outside of the head. It has Maximum Radial Section because of which it has most extreme pressing factor dispersion zone. Thus, Hemi Heads Thickness is generally 50% of the shell Thickness for same temperature and pressing factor.


Torispherical Heads or Flange and Dished Heads

Torispherical Heads or Flange and Dished Heads

It's outspread area is more than different heads however lower than the ellipsoidal Heads. These heads have a Dished with a fixed span (for example CR), and the size of its is relies upon the kind of torispherical head. The section between the dish and the chamber is known as the knuckle and it has toroidal shape. These head's thickness is practically 1.77 occasions the Shell Thickness.


Flat Heads

Flat Heads

They are the essential type of the pressing factor vessels heads which are less valuable in Pressure vessels heads. It has lower outspread area as contrast with different heads because of which it has less pressing factor withstanding limit.
