Heat treatments are fundamental processes in industries such as heavy boiler making, offshore, shipbuilding, oil & gas, and steel production. They allow the modification of material properties to ensure strength, dimensional stability, and durability. But what equipment makes these processes possible? In this article, we break down the main systems used by Intec-Heat to carry out industrial heat treatments safely, precisely, and efficiently.
ELECTRIC HEATING EQUIPMENT: FLEXIBLE HEATING PADS, BLANKETS, AND BANDS
Electric heating systems are the most widely used due to their reliability, safety, and adaptability to any geometry.
At Intec-Heat, we employ:
-
Blanket or band-type heaters: ideal for preheating and PWHT (Post Weld Heat Treatment) on pipes, flanges, tanks, or complex metal structures.
-
Snake-type heaters: allow efficient coverage of irregular surfaces.
-
Specialized supports and fixtures: to prevent direct contact with welds or critical areas.
This type of heating is particularly useful for localized work, field repairs, or workshop prefabrication. Additionally, it integrates with advanced thermal control systems that enable complete process traceability.
INDUCTION SYSTEMS: HIGH EFFICIENCY AND LOCALIZED CONTROL
Induction heating is a high-performance technology that enables highly localized heating without physical contact, using high-frequency cables wound around the component.
Key advantages:
-
Rapid achievement of target temperature.
-
Increased safety by eliminating exposed heating elements.
-
Uniform heating, ideal for sensitive materials or specific geometries.
PORTABLE AND FIXED FURNACES: MODULAR SOLUTIONS FOR LARGE PARTS
For mass treatments or serial work, furnaces are the most efficient solution:
-
Modular portable furnaces: adapt to large-sized or complex-shaped parts (pipes, structures, frames).
-
Fixed industrial furnaces: used in workshops for series of components or parts requiring repeatability and absolute control.
At Intec-Heat, we design and operate our own gas- or diesel-fired furnaces, especially effective for post-weld heat treatments (PWHT) or refractory drying. Their modularity allows for use both in the field and in industrial plants.
CONTROLLERS, SENSORS, AND DIGITAL MONITORING SYSTEMS
Automation and control of heat treatment are as important as the heating itself. At Intec-Heat, we work with:
-
Multi-ramp programmers with customized profiles.
-
Type K thermocouples and infrared sensors for precise measurement.
-
HMI/SCADA systems enabling real-time visualization, remote control, and automatic logging of critical parameters.
-
Integrated alarms to prevent thermal deviations or overheating.
This control layer ensures traceability and compliance with international standards (ASME, ISO, API), which is crucial in sectors like petrochemical, shipbuilding, or aerospace.
CRITERIA FOR SELECTING THE RIGHT EQUIPMENT FOR HEAT TREATMENT
Each project is unique; therefore, choosing the right heating equipment depends on multiple factors:
-
Type of treatment: preheating, PWHT, refractory drying, etc.
-
Component material: carbon steels, stainless steels, special alloys.
-
Geometry and accessibility: flat parts, curved surfaces, interiors, large volumes.
-
Working environment: workshop, field, offshore, confined spaces.
-
Regulatory requirements: temperature, duration, recording, document validation.
At Intec-Heat, we analyze each technical need and propose the most efficient and safest solution, whether it involves resistance heating, induction, furnaces, or internal combustion systems.
