During the welding process there is a lot of opportunity for stresses to build up. High residual stress can be a source of corrosion and cracking, while also creating brittleness. Hydrogen-induced cracking is another risk to be reckoned with during welding. All these factors can severely reduce the life-span on the welded component (pipe, structure, equipment).
We can provide the full suite of heat treatment services. This includes:
Pre-heating and post weld heat treatment (PWHT).
Metal properties enhancement (e.g. normalizing, annealing).
Specialty services (e.g. dewaxing, refractory dry-out, debolting).
In this way stresses can be reduced, hydrogen removed, ductility and toughness increased and hardness reduced.
Right temperatures & durations
We can support you in determining what heat treatment would best suite your needs: what temperature to pre-heat to (if needed) and what temperature profile to apply during the cool-down period.
If required, we use Finite Element Analysis (FEA) to simulate the loads on structures and transfer of heat. We can also advise on the best equipment to do this with. (e.g. electrical resistance, induction, high velocity burners or furnaces.)
Full range of heat treatment services
We have heat treatment technicians, processes and Cooperheat equipment in-house to efficiently execute all your heat treatment jobs. This can range from quick interventions (making use of Cooperheat K9 equipment) to heat treatment services on large and complex projects.
Thanks to Cooper8 software, our technicians can monitor several heat treatments at the same time, reducing the costs related to our services.
For large or more complex projects
Thorough pre-planning is required for larger / more complex the heat treatment projects.
This could be construction projects requiring many on-site technicians, but this could also be related to the heat treatment of very large equipment. E.g. 30 meter diameter spheres, hydropower bifurcations measuring over 5 meter in diameter and 88 millimetre wall thickness, and critical lines in nuclear facilities where there is very limited time to apply PWHT equipment.
Peace of mind
Irrespective of who is executing the heat treatment, if Cooper8 heat manager software is being used, our experts can remotely keep an eye on heat treatments. This doesn’t absolve local technicians doing their job, but helps avoid mistakes.
Note: both our experts as your own experts can watch over technicians in the field, even if they are not at site.
Full range of equipment
If you’re interested in self-performing heat treatments, Cooperheat’s industry reference equipment is available to rent or buy. If required, we can also train your technicians to use this equipment.
