Product Description

40KW Heating Induction Post Weld Heat Treatment Machine for Pipeline/Preheating Machine

An air-cooled induction heater is a modern industrial machine that uses electromagnetic induction to heat up metal objects, but with a very practical twist: it uses fans to cool itself down instead of requiring water.When you wrap a special High-temperature electromagnetic wire around a metal part (like a pipe or a large gear) and turn the machine on, it creates a magnetic field. This field makes the metal heat up rapidly and evenly on its own, without any open flames.

Specification

Applications
1.Preheating: Heating pipes, steel structures, or pressure vessels before welding to prevent cracks.
2.Post-Weld Heat Treatment (PWHT): Used for stress relieving or hydrogen removal after welding to improve the mechanical properties of the weld.
 
3.Common parts include: Bearings, gears, couplings, shafts, motor rotors, and rollers in paper-making machinery.
 
4.Fluid Heating: Heating crude oil pipelines, water pipes, or reaction gas pipes to prevent the medium from freezing or to maintain reaction temperatures.
5.Vessel Maintenance: Heating and(insulation) for storage tanks, boilers, and zinc baths.
 
6.Mold Heating: Preheating and maintaining the temperature of various industrial molds.
7.Pre-processing: Preheating metal workpieces before spraying or bending.
8.Specialized Heating: Localized heating for large or irregular metal structures, such as ship or aircraft carrier decks.
 

The advantages of air cooled induction heater 

1. Ultimate Portability and Easy Installation
Because these machines don't require an external water supply, cooling towers, or heavy water hoses, they are incredibly easy to set up and move around.
2. Excellent Environmental Adaptability
The air-cooled design allows these machines to operate reliably in various challenging environments:
3.Don't need water :Installation is simple. It can be moved to outdoor work. The equipment has a long service life, is easy to maintain, and is simple and easy to operate.
4.High security: Built-in multiple security protection systems to safeguard staff and equipment

FAQ

Q:Which manufacturing applications use induction heating machine ?
A: · Joining: brazing, soldering, shrink-fitting
· Heat treating: hardening, tempering, annealing, stress-relieving
· Forming: billet, bar, and tube pre-heat for forging, extrusion, and bending
· Bonding & curing: adhesives, paints, composites, cap-sealing
· Industries span automotive, aerospace, EVs, semiconductors, oil and gas, medical, consumer-appliance, and heavy equipment..
 
Q:What materials can be heated with induction heating technology ?
A:Induction heating systems can heat almost all electrically conductive metals, including steel, stainless steel, copper, aluminum, and brass. Because heat is generated directly within the metal, both ferrous and non-ferrous materials reach target temperatures rapidly and uniformly. By adjusting coil design, frequency, and power output, induction technology ensures optimized performance across diverse industrial applications such as hardening, brazing, and forging.
 
Q:How do i choose the right frequency and power for induction heating system ?
Selecting the proper induction heating frequency and power level depends on your material type, part geometry, and heating goals. Low frequencies provide deeper heat penetration for larger parts, while high frequencies focus energy at the surface for precision surface hardening. Our induction heating experts help determine the optimal parameters to deliver consistent heat profiles, maximum process efficiency, and repeatable results for your industrial manufacturing process.
