DISHED-END MANUFACTURING

At Ravi Green, we manufacture tank heads in many different configurations and form carbon, stainless, aluminum, and many other exotic materials using the best head making equipment available today.
 
We possess capability to manufacture ASME® and non-code tank heads for various industries and applications like Semi-elliptical tank heads, ASME® flanged and dished tank heads,  ASME® 10-10 flanged and dished tank heads, ASME® high crown flanged and dished tank heads, standard flanged and dished tank heads,  flanges and shallow dished tank heads, flanged only tank heads, and dished only tank heads.
 
The production of heads and bottoms is through the cold forming process that involves dishing and flanging forming processes.
 
The first forming process "dishing" (excluding flat bottoms) is carried out on modern hydraulic dishing presses. Our workshop in Lahore possesses hydraulic presses with up to 1000 ton force capacity.  
 
After shaping the crown through dishing, the bottom or head is given its final shape by flanging the knuckle radius. We possess the capability to flange dishes ranging from 1 meter to 5 meters in diameter and thicknesses up to 30mm. Here, the material forms between a forming and pressure roller such that the dish exhibits a straight flange at the point of connection with vessel shell.

Once dishing and flanging are complete, the next step is edge preparation. We process these edges utilizing plasma or thermal cutting, or through mechanical abrasion. The type of edge processing takes place per your wishes.
