Power plant, boiler & processing
Creep-resistant materials and special parts for power-plant and boiler technology – superheater coils, membrane walls and drilled tube sheets. Plus processing, measurement and documentation.
Components & codes
Manufactured to your drawing and the relevant codes – EN 12952 (water-tube boilers), EN 12953 (shell boilers), AD 2000 and the Pressure Equipment Directive 2014/68/EU.
| Component | Description | Code |
|---|---|---|
| Superheater coils | bent coils from creep-resistant boiler tubes | EN 12952 · PED |
| Economiser / membrane walls | heat-exchanger surfaces to drawing | EN 12952 |
| Tube sheets / drilled plates | drilling pattern as specified (e.g. 3-pass boiler) | EN 12953 |
| Boiler tubes | creep-resistant, seamless | EN 10216-2 |
Material grades (creep-resistant)
Creep-resistant and high-temperature steels for boilers, superheaters and steam lines – to DIN EN and with ASME/ASTM equivalent.

Processing and manufacturing
Sawing, flame cutting, plasma and laser cutting, weld bevels and drilling – plus cold-bending of pipes into coils and bends to radius.
We supply welded assemblies to EN ISO 3834 with qualified procedures (WPS/WPQR). On request with on-site measurement, a 3.1 / 3.2 mill certificate and full documentation.
Delivered components
Completed projects from boiler and plant engineering – superheater coils, tube coils with header and drilled tube sheets from creep-resistant materials.
