our dished heads are used in a variety of applications and industries such as storage tanks, pressure vessels, road tank, food processing operations, chemical plants ,Nuclear operation, Oil Refining, Architectural feature, power generation.
Due to our forming experience and equipment, we can spin or press the first part of the process of forming your products, It depend on the thickness and material performance,
Our main products are 2:1 SE dished heads, Torispherical heads, Cones,Hemispherical heads etc
Choosing the right type is the key decision for each customer and one for which our experience team to happy to give advice, simple speaking, the torispherical heads, the less ressure it can withstand, Conversely, the deeper dished heads, for example Elliptical heads, hemispherical, the greater pressure it can take.
Our in house-capability to form dished heads by cold press brings major benefits to our customers and sets us apart from others dished heads manufactures
For carbon steel dished heads, we can forming this dished heads from 76-9000mm in diameter and below 250mm in thickness
The general forming process as the below sketches

The series KCB/2CY gear oil pumps possess the advantages of simple and compact structure, easy operation and simple maintenance. The series KCB gear oil pumps are suitbble for transporting various oils such as petroleum, diesel and lubricant oils. When using copper gears, the pumps can converfluids with low flash points such as gasoline and benzene ate temperature below 70º C.
They are widely used in oil reservoirs, piers, ships, mining sites, factories and farms. The series 2CY gear oil pumps are mainly used for transporting viscous lubricants for mechanical equipment. When equipped with stainless steel gears, the pumps can pump cooking oils or beverages.

1,Our material (hot Rolled Unalloyed structural steel, high and low temperature steel, High Alloy steel)
We have no carbon steel plates in our stock and most of plates are from Chinese steel market or mill. Meanwhile As Japanese owed company, We can also source the plates from Japanese ex-mill if end user can`t accept ex-chinese mill.
Basically the delivery time shall be below 20days for dished heads if plates are from steel market. and Max plates width from them is below 2200mm. it means that the seamless dished heads diameter shall be below about 1800mm.
The max width CS plates that Chinese mill can do is below 4700mm,and dished heads can be seamless below 3800mm in diameter.
