Dachuan Group received orders for 10 million nuclear power projects
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 nuclear island container (first batch) project of the first phase of Liaoning Xu Dabao Nuclear Power Plant is the largest nuclear power project order undertaken by the Dachuan Group, achieving a breakthrough of “zero†for the 10 million yuan order of nuclear power products. Previously, the Big Ship Group and China Nuclear Power Engineering Co., Ltd. had two successful cooperations. During the bidding process of the project, the Big Ship Group formulated detailed countermeasures for the project manufacturing difficulties and obtained the evaluation committee of China Nuclear Power Engineering Co., Ltd. It is highly recognized and laid a solid foundation for the subsequent accumulation of nuclear and tertiary pressure vessels and heat exchangers.
At present, the Big Ship Group has become more and more well-known in the domestic nuclear power field. It has accepted the invitation of well-known nuclear power giants such as China Nuclear Energy Technology Co., Ltd. and China Nuclear Power Engineering Co., Ltd., and participated in the waste heat of the demonstration project of the high-temperature gas-cooled reactor nuclear power plant in Huaneng Bay, Huaneng. The bidding activities of the project water wall equipment, CB type structural modules of No.1 and No.2 units of Liaoning Xudabao Nuclear Power Plant and other projects show the strong development momentum of the large ship group nuclear power project. 
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.
