Radiant Tubes
When you want to count on radiant tubes that offer a consistent heat transfer, count on Alloy Engineering. Our fabricated tubes have a low mass that enhances heat transfer for maximum efficiency while reducing energy and operating expenses. Made from ductile, high-nickel, low carbon alloys with a controlled, tight grain structure, our radiant heat tubes outperform the tubes they replace to give you a longer life, increased production and reduced maintenance, and energy costs.

Engineering Advantage
Our ASME–certified engineers take the time to understand how and why a radiant heat tube fails. That’s why they may use multiple grades of wrought materials in a fabrication to enhance the performance of specific areas of a tube. Our team will rebuild or produce new radiant tubes, depending on your needs. 

Design Flexibility
Alloy Engineering fabricates tubes in any configuration and wall thickness and supports all furnace OEM tube designs. For your convenience, we can repair and or replace return bends, flanges, bungs and straight components onsite. Ask us about our flame twisters, insulation plugs, tube supports and bellows. 

Variations of our radiant tubes include:

  • Double ‘P’ Tubes
  • Straight tubes
  • W-tubes
  • U-tubes
  • Bungs, mounting flanges and insulations


  • Thin and lightweight tubes resist sagging and cracking
  • High resistance to thermal fatigue
  • Thermally efficient tubes provide energy savings
  • Sizes range from 2″ to 12″ 
  • Outer diameter tubes and wall thickness is 16 gauge to 3/8″
  • Stainless steel or nickel alloys
  • Return bends assure uniform metal section, consistent heat transfer
