Heat treatment
Our heat treatment services are in compliance with the ISO standards and VCA
Petrochemical safety standards. The measurement and control system is regularly
calibrated for maximum reliability, while the organisation and processes are
inspected and certified by independent inspection bodies.
Heat treatment methods
- Electrical resistance heating elements
- Electrical furnaces
- Gas or oil-fired furnaces
- Induction
Specific heat treatment services
- Preheating and Post Weld Heat Treatment
- Annealing of large and heavy structures in an on-site mobile furnace
- Annealing os structures and steel parts in stationary furnaces on the operating sites
We use modern and advanced heat treatment equipment with different capacities and capabilities. The process is monitored and checked with a measurement and control system. Following every heat treatment process, the customer receives a detailed report with a heat treatment certificate and temperature diagram.
