Ethylene, aromatics, methanol and polymer plants run continuous processes where a finned tube failure means an unplanned shutdown. Our tubes are built to project specifications with full traceability.
Duties we supply
- Quench and interstage coolers in olefin plants.
- Aromatics and methanol plant air coolers.
- Polymer and resin plant heaters and coolers.
- Steam condensers and reboiler support exchangers.
Why petrochemical projects specify welded fins
In petrochemical service the process stream often combines elevated temperature with hydrogen, sulphur or chlorides. A metallurgical fin-to-tube joint removes the risk of the fin loosening during thermal cycling and keeps the thermal performance predictable for the design life. Laser and HF welded tubes are therefore common, with base tube material matched to the process specification.
Documentation
- EN 10204 3.1 mill certificates for base tube and fin strip.
- Dimensional inspection reports per bundle.
- Hydrostatic or pneumatic test records where required.
- Third-party inspection (SGS, BV, TÜV) can be arranged on request.
If your project follows a specific client specification — Shell DEP, Aramco, ADNOC, Total or an EPC house standard — send the relevant sections and we will confirm compliance before quoting.
