02 / HEAVY FORMING
18,000T Heavy Plate Forming
Machine capacity is a starting point for a technical conversation, not a universal product limit.
18,000T Press in Production
Source production example: Q355 plate, 100 mm thickness and 12 m length. This example does not establish a guaranteed forming envelope; grade, geometry, length and tolerances require engineering review.
Primary forming equipment
| Forming force | 18,000T |
|---|---|
| Processing thickness | 20–150 mm |
| Pipe/forming range | DN560–1800 |
| Forming length | Up to 13,000 mm |
| Machine | TDY39K-18000/13000mm |
Actual feasibility depends on material grade, OD, thickness and length.
