Whether you’re working on a power plant shutdown, a petrochemical turnaround, or a pipeline maintenance project, our onsite combustion heating solutions are engineered for speed, safety, and thermal accuracy across all demanding industrial environments.
Our clients in Houston’s booming energy, chemical, and manufacturing sectors rely on our proven combustion heating process to achieve consistent temperature profiles, eliminate cold spots, and ensure metallurgical integrity during fabrication, repair, or post-processing. If you're dealing with thick-walled vessels, pressure-rated piping, or critical weld areas, combustion heating is the cost-effective, field-ready solution.
What Is Combustion Heating and Why Does It Matter?
Combustion heating refers to the use of controlled flame, typically fueled by natural gas, propane, or diesel, to deliver high-temperature, consistent heat to industrial components or structural materials. The core purpose? Achieving precise thermal conditions during preheating, interpass heating, or post-weld heat treatment (PWHT).
In Houston’s industrial zones, from the Ship Channel to Baytown and beyond, combustion heating is often used for:
- Preheating before welding to reduce the risk of cracking
- Post-weld heat treatment (PWHT) to relieve residual stresses in welded materials
- Hydrogen bake-outs for pressure vessels and pipeline sections
- Dry-outs and heat soaks in refractory-lined equipment
Compared to resistance or induction methods, combustion heating offers greater portability, larger coverage areas, and faster ramp-up times. It’s ideal for fieldwork where mobility and adaptability are critical.
Why Houston Industries Rely on Onsite Combustion Heating
Houston is home to one of the largest concentrations of energy infrastructure in the world. From oil and gas refineries and LNG facilities to power generation stations and offshore modules, each facility depends on consistent, code-compliant thermal treatments. Onsite USA brings the heat directly where it’s needed.
Here’s what makes our approach trusted across Southeast Texas:
Field-Ready Flexibility
Our mobile combustion heating rigs are designed for tough terrains, vertical applications, and confined spaces, perfect for Houston’s refinery turnarounds and midstream operations.
ASME and AWS Code Compliance
We strictly follow applicable standards including ASME Section VIII, B31.1, B31.3, and API specifications for code-mandated thermal cycles.
Trained Combustion Heating Technicians
All combustion technicians are certified and safety-trained for high-temperature operations in classified areas and confined spaces. We're not just equipment providers, we're experienced thermal partners.
Temperature Accuracy and Control
We use thermocouple feedback systems, thermal mapping, and multi-zone burners to maintain controlled ramp rates, soak times, and cooldown periods with minimal variation.
Our Combustion Heating Capabilities in Houston
1. Pipe & Vessel Preheating
Before welding, high-carbon or alloy steels require preheating to avoid hard zones and thermal shock. We provide combustion-based preheat using torches or manifold burners, controlled by calibrated thermocouples. Typical preheat temperatures:
- Carbon Steel – 150°F to 300°F
- Chrome-Moly (CrMo) – 300°F to 600°F
2. Post Weld Heat Treatment (PWHT)
We apply controlled heating after welding to relieve stress and restore ductility. Our combustion systems follow precise heating profiles for thickness, alloy type, and geometry.
3. Refractory Dry-Outs
Combustion heating accelerates dry-out processes for new or repaired refractory linings in furnaces, boilers, and HRSG units.
4. Hydrogen Bakeouts
In Houston’s refining and petrochemical facilities, hydrogen bakeouts before hydrotesting are essential. We provide combustion-based heating at controlled ramp rates to ensure hydrogen removal.
5. Structural Steel Heat Treatment
Large structural members, bridges, or offshore modules in fabrication yards around Houston often require controlled heating prior to fit-up or bolting operations.

Combustion Heating vs. Other Methods
| Heating Method | Ideal For | Limitations |
|---|---|---|
| Combustion Heating | Large surface areas, field jobs | Requires flame safety & ventilation |
| Electrical Resistance | Controlled environment, small parts | Requires power access, slower heat-up |
| Induction Heating | Localized, rapid heating | Not suitable for complex geometries |
Combustion heating bridges the gap between speed and scale, especially when you can’t afford downtime or logistics of moving oversized equipment.

Frequently Asked Questions
What is a combustion heating system?
A combustion heating system uses the controlled burning of fuel, such as natural gas, propane, or oil, to generate high-temperature heat for industrial applications like welding preheat, PWHT, or refractory dry-outs.
How do you heat combustion?
Combustion heat is generated by igniting a fuel-air mixture using burners or torches. The flame transfers heat directly to materials or through thermal conduction, raising component temperatures as required by the process.
What is the difference between combustion and heating?
Combustion is the chemical process of burning fuel to release energy. Heating is the result of that energy being transferred to a material or space to raise its temperature.
What is the point of combustion heat?
Combustion heat is used to achieve controlled temperature increases for processes like stress relief, welding preparation, or curing, ensuring structural integrity and compliance with metallurgical codes.
What are the advantages of combustion?
Combustion heating is fast, scalable, and ideal for field applications. It offers high heat output, flexibility in setup, and cost-effective thermal treatment for large components or hard-to-reach areas.
