Introduction
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 torishpherical 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 Cold Forming dished heads, Hokkai have two ways to forming which range is from 76-9000mm in diameter and below 44mm in thickness. Hokkai have 630T,2000T,6000T press machine for cold press and FM3.5,FM6.5,FM8.8 spinning machine for cold spinning
The general forming process as the below sketches
