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.
