Keep refinery turnaround work moving with on-site heat treatment from Axiom HT. From vessel preheat and PWHT to weld overlay, get planned support for critical refinery equipment and project schedules.
Refinery turnarounds demand careful planning, efficient execution, and strict attention to code requirements. Heat treatment plays an important role in preparing and treating critical equipment during maintenance and repair work.
Axiom HT provides refinery heat treatment services for vessel preheat, post-weld heat treatment, and weld overlay, with additional solutions for piping, heat exchangers, heaters, and valves.

Blended heating solutions
Applies controlled heat to metal before and during welding to achieve the required temperature and support weld integrity.
Relaxes residual stresses introduced during welding and other processes, including high-pressure piping applications.
Axiom HT provides blended heating solutions for weld overlay applications, alongside vessel preheat and post-weld heat treatment.
Different equipment and project requirements call for different heating approaches. Axiom HT offers three primary heating methods.
| Method | How it works | Applications |
|---|---|---|
| Electrical Resistance | Uses flexible, low-voltage ceramic heating elements. | Preheat, PWHT, hydrogen bake-out, post-heating, and thermal stabilization. |
| Induction | Uses electromagnetic fields to generate heat directly within metal. | Preheat, PWHT, hydrogen bake-out, line thaw, annealing, and tempering. |
| Combustion | Uses low-pressure gas and high-velocity air to heat large structures. | PWHT, refractory dry-out, and pressure vessel heat treatment. |
Refinery turnarounds require careful coordination of heat treatment and cooling. Axiom HT's Axi-Therm approach combines one, two, or all three heating methods simultaneously to maximize temperature dissipation into the heated area.
Once the required metal design criteria have been met, a cooling method is applied. This approach is designed to reduce upfront costs and improve the time required to return equipment to production.
Refinery heat treatment requires the right combination of technical expertise, equipment, and project coordination. Axiom HT offers on-site services backed by 135+ years of combined experience, three heating methods, and its Axi-Therm blended heating and cooling approach. From initial planning to project execution, the team focuses on quality, cost control, and meeting demanding project requirements.
During a refinery turnaround, heat treatment planning can influence project budgets, schedules, and the time required to return equipment to production.
