Thermal Capabilities Tailored to Scope, Site, and Safety
Industrial Thermal Services delivers engineered heat treatment across fixed furnace facilities and on site environments. We support pressure-bound components, structural weldments, refractory systems, and high-spec materials. All procedures are aligned with ASME and API code standards and include calibrated monitoring, QA traceability, and qualified technician oversight.
Post Weld Heat
Treatment ( PWHT )
Controlled thermal cycles for critical weldments using mobile resistance, induction, and fixed furnace methods.
Resistance Heat
Treatment
Localized field heating using calibrated consoles and digital temp logging for precision preheat, bake-outs, and disassemblysupport.
On Site Heat
Treatment
Field-rigged thermal setups engineered for vessel zones, structural welds, and site-specific geometries.
Annealing &
Normalizing
Furnace-based cycles to modify material microstructure, reduce hardness, and restore ductility.
Bake Out
& Dry Out
Controlled ramp cycles and moisture evacuation for boilers and lined vessels prior to startup.
Preheating
Uniform heating to reduce thermal gradients and weld stress before joining operations.
Combustion &
Induction Heating

Heating Systems
Our mobile rigs, consoles, and modular elements are engineered for on site heat treatment in high-stakes industrialHeat Treatment for Pressure Vessels & Welds4environments—from pressure vessels to structural assemblies.
QA Driven
Process Controls
All heat treatment services include calibrated thermocouples, digital temperature tracking, and full post weld heat treatment documentation packages.
Specialized Technician
Experience
ITS teams are trained in resistance heat treatment, induction, furnace operations, and site-specific procedures with confined space, rigging, and AWS/ASME certifications.
Proprietary
Simulation Tools
We integrate 3D heat treatment software and FEA modeling to simulate setup geometry, predict soak zones, and minimize site rework.
Proven Safety
Record
ITS maintains a TRIR of 0.00 for over 15 years across thousands of site hours, backed by documented safety procedures and technician certifications.
ASME and API
Code Alignment
Every treatment method is engineered to meet or exceed relevant sections of ASME, API, and project-specificstandards.
Compliance & Safety Protocols
Industrial Thermal Services delivers post weld heat treatment and on site heat treatment solutions engineered to meet ASME, API, and project-specific requirements. Each application is executed with calibrated thermocouples, PLC-controlled ramp and soak sequences, and full QA documentation packages tailored to customer specs.
Our technicians follow written procedures that incorporate hold time verification, material matching, and thermal profiling. Resistance heat treatment and other precision methods are verified using multichannel data loggers and dual-Heat Treatment for Pressure Vessels & Welds5 redundant sensor arrays.
Digital records are maintained for temperature traceability, and job packages can be integrated into client QC systems or submitted for third-party review.
Proprietary Capabilities & Operational Expertise
Industrial Thermal Services equips every job with engineered systems and proprietary planning tools designed to meet the demands of regulated sites.
Our mobile heat treatment units are configured for confined spaces, vertical vessels, elevated pipe racks, and other complex geometries. These systems deliver on site heat treatment without compromising cycle control.
Technicians deploy wireless consoles, remote thermocouple monitoring, and digital temperature logging to ensure full visibility during preheat, post weld heat treatment, and refractory bake outs.
For projects requiring precision layout, our teams use 3D modeling and finite element analysis to simulate rig configurations, clearance, and zone heating requirements prior to mobilization.
When fast mobilization is critical, modular resistance rigs and containerized toolkits enable deployment to active units, power blocks, and high-clearance locations with minimal setup time.
Applications &
Industries Served
Industrial Thermal Services delivers code-compliant heat treatment solutions for in-process assets, capital projects, and maintenance turnarounds across critical industries. Each treatment plan is configured for material specifications, geometry, and code requirements, supported by experienced technicians and full QA documentation.
Case Studies

Finite Element Analysis for Post Weld Heat Treatment
A petrochemical company based in the U.S. was fabricating a large, high-pressure vessel with multiple nozzle attachments. These full-penetration welded nozzles are critical to the vessel's safe operation, which involves extreme pressure and temperature. To meet ASME Section VIII requirements and ensure long-term reliability, the client needed Post Weld Heat Treatment (PWHT) to relieve residual stresses and enhance material toughness.
