Fabricated in sections and joined by welded seams — the answer when a required diameter exceeds what a single plate or forging can practically provide, common on the largest condensers.
| Structural Principle | Multiple plate sections joined by full-penetration welded seams |
| Typical Diameter Range | Beyond single-piece limits, 2500 mm+ |
| Joint Method | Full-penetration welded seams, radiographically inspected |
| Best Suited For | Very large condensers and heat exchangers |
| Governing Codes | ASME Section VIII welded-joint requirements |
Segmentation is a sizing decision, applied once single-piece limits are exceeded.
There's no single universal number — it depends on available plate/forging sizes from the specific material and supplier, but very large condensers beyond roughly 2500-3000 mm commonly require segmental construction.
Not when properly designed and inspected — the seams are full-penetration welds verified by radiography or ultrasonic testing, engineered to meet the same code requirements as the parent material.
Yes, though weldability varies by material family — some alloys require more careful heat input control during the seam weld than others, which is factored into the fabrication plan.
