Our Heat Treatment Methods

While we pride ourselves on our patented cooling solutions, we also offer full service on-site heat treatment services. 
Our experts in Resistance, Combustion, Induction and Pressure Vessels are ready to help make your next project a success.

Electrical Resistance

Uses flexible low voltage electrical resistance heating elements.

Traditionally the most utilized, the low-voltage electrical resistance services model helps with a quick and precise control of the heat by using small flexible ceramic resistance heating elements of 40 to 80-volt power. The varying sizes of the flexible ceramic elements often provide a suitable approach for many components and for those with complex geometries, whether it is Preheat, Bake Out, or PWHT.

Combustion

Uses high-velocity gas and air mixture creating high and or low heat through applying positive pressure causing a scrubbing action and a positive pressure which forces heat across the face of, and through the thickness of components. 

By utilizing high-velocity burners placed strategically through firing ports, the combustion method is a very cost-effective application that can be utilized for refractory dry-outs, furnace heat-ups, start-ups, and a myriad of other applications in many global industries including refining, chemical, cement, and pulp and paper.

Induction

Uses high-frequency currents through various air and water-cooled coils, creating a safe, efficient, and rapid heating application.

Becoming more prevalent in field service applications, high-frequency electrical currents create a magnetic field and molecule movement in the component metal that heats faster than other more conventional heating methods. The quicker heating and air or water-cooled coils used on the workpiece make this a safe and practical application for high production activities.

Pressure Vessels & Tanks

Using a patent-pending method where all heat transfer types, as well as various cryogenic cooling solutions, are considered to reduce cost and schedule and get you back to production quicker.

Read our whitepaper on how our patent-pending method of heating and cooling your pressure vessels and tanks can reduce cycle time by 30%.

What Heat Treatment Achieves

Heat treatment directly affects the mechanical properties and service life of metal components. Proper heating and controlled cooling ensures metals meet required design and safety standards.

The key metallurgical objectives include:
Strength – Resistance to deformation under load
Ductility – Ability to stretch without fracture
Malleability – Ability to shape and machine safely
Hardness – Resistance to wear and penetration
Incorrect heating or cooling can lead to cracking, embrittlement, or failure in service.

Our Heat Treatment Services

We specialize in the following heat treatment applications:

Pre-Heat

Is a process of heating the metal to the desired temperature and maintaining this before and during the welding process.
Learn More

P.W.H.T

PWHT is the relaxation of residual stress caused during the welding or in other processes such as high-pressure piping and is also effective for hydrogen removal. 
Learn More

Bake Out

(Hydrogen Bake Out)  Is a heat treatment process that drives out any hydrogen that may have occurred during welding or has seeped into the parent metal in an in-service process pipe, vessel or structure.
Learn More

Post Heating

Is the maintenance of preheat after the weld has been completed, which allows hydrogen dissolution from the weld to occur. The post-heat temperature may be the same as, or greater than, the original preheat temperature specified. 
Learn More

Line Thaw

Is applied heat to help liquify congealed or solidified product in a process system.
Learn More

Electrical Resistance

Heating that uses low-voltage ( 80volt) flexible ceramic heating elements placed around the component controlled by multi-point heat treatment control consoles.
Learn More

Induction

Is heating that uses an electromagnetic field to create a disturbance in the molecules of the metal that creates heat, the frequency of the electromagnetic field can be quicker than traditional electric resistance heating, the system is quicker to set up and is a good tool for some heat treatment applications. 
Learn More

Combustion

Is used to heat large structures inside temporary furnaces, vessels, lime kilns, and other large structures because of its efficiencies. Utilizing gas and air to force the heat into the area requiring the heat treatment creates a uniformity that heats the intended area.

What Does Heat Treatment Cost?

Field heat treatment is what separates a weld that lasts from one that fails quietly a few weeks later. On-site welding traps stress inside the metal, creating hidden risks of cracks, warping, or sudden failure.  Applying controlled heating and cooling right where the equipment sits not only stabilizes the metal but also protects pipelines, pressure […]

Induction Heating vs Resistance Heating

Induction heating vs resistance heating is one of those decisions that can make or break your line. One blasts heat fast and precise, the other spreads it slow and steady. Pick wrong, and you waste energy, slow down work, and stress your equipment.  In this guide, we cut through the jargon, break down how each […]
