Stainless Steel Dished Ends manufacturer in India

DIN 28011 Carbon Steel Torispherical Heads and Tank Dished Ends supplier in Mumbai.

Carbon steel Dish End Manufacturer in India produce the dish ends in different types, dimensions and material grades. The dish ends are products that are used in pressure vessels and high pressure boilers to keep the end closed. The MS dish end cap is made up of mild steel where there are different shapes to the dishes such as cone shape, flat type and different other types with different dimensions. The Ellipsoidal dish end has an elliptic curve on the outside of the dish. Their outside diameters can range up to 5000mm and their wall thicknesses can range from 3mm to 60mm. The Carbon steel pipe end caps are part of the dish ends.

Carbon Steel Pipe End Caps

Carbon Steel Pipe End Caps

These are used to close the connection of a pipeline. The installation of the different Dished boiler end types can be through screw, threading, welding or a combination of thread and weld. There are different material grades used such as 304, 316 austenitic grades, carbon steel grades, alloy steel grades and martensitic steel grades. The Carbon steel dished ends have high toughness and can withstand high wear and tear. They are also easy to weld with. The carbon steel is also low in cost compared to the alloy steel dish ends. The CS Dished end cap is therefore used in most applications in the general corrosive range.


The sensitive and expensive applications use more complex, expensive and mechanically higher grades of materials. The SS torispherical dished end is usually made through thermal expansion or drawing process to get the right shape. The arc, inside diameter, outside diameter, wall thickness and pressure capacities all differ from the usual Elliptical dished end. The different types of cap ends are used in oil and gas, agriculture, fertilizer, petroleum, petrochemical, food processing, water lines and in many other industrial applications.

Pressure Vessel Dished Ends


❯❯ Pressure Vessel Dish End Types :

❖ Ellipsoidal Heads

Ellipsoidal Heads

They have wider Radial section for pressure distribution. It is also called as 2:1 elliptical head. The Head height is a quarter of the diameter. The radius of it may vary from minor to major axis. It resist more pressure as compare to other heads.


❖ Hemipherical Heads

Hemipherical Heads

The shape of head is sphere, because the pressure in the vessel is divided equally across the surface of the head. It has Maximum Radial Section due to which it has maximum pressure distribution area. So, Hemi Heads Thickness is roughly half of the shell Thickness for same temperature and pressure.


❖ Torispherical Heads or Flange and Dished Heads

Torispherical Heads or Flange and Dished Heads

It's radial section is more than other heads but lower than the ellipsoidal Heads. These heads have a dish with a fixed radius (i.e. CR), and the size of its is depends on the type of torispherical head. The passage between the dish and the cylinder is called the knuckle and it has toroidal shape. These head's thickness is almost 1.77 times the Shell Thickness.


❖ Flat Heads

Flat Heads

They are the basic form of the pressure vessels heads which are less useful in Pressure vessels heads. It has lower radial section as compare to other heads due to which it has less pressure withstanding capacity.
