| FORGED SHELLS have always been one of the
main products of JSW. |

Advantages of Forged Shell Construction |
|
|
The combination
of high quality forgings and less welded
joint construction, the best manufacturing
process for high duty pressure vessels
with a large diameter and heavy thick
wall, offers the following significant
advantages: |
|
|
|
|
 |
Elimination of longitudinal seam(s)
subjected to the highest stress due to
internal pressure resulting in higher
integrity of the vessel. |
|
|
|
| |
|
Homogeneous and better properties (mechanical
and metallurgical) throughout the heavy
wall thickness compared with plates from
ordinary rolling process. |
|
|
|
| |
|
Higher dimensional accuracy of the vessel
(i.e. inside diameter, wall thickness,
and weld edge alignment), improving efficiency
in fabrication, safety and reliability
of the vessel. |
|
|
|
| |
|
Reduction of the fabrication period
and extent of ln-Service lnspections (ISl)
due to shorter weld seams. |
