new raw material PMI to guarantee the physical properties of the tubes;Uniform wall thickness; 
radiant tube

 

The various radiant tubes made by HEXIN are normally for continuous strip processing furnaces of steel mills, like U shaped, 

W shaped, P , double P shaped ,customized shape, tube temperatures up to 1250°C, according to the furnace design.

 

 

Materials

   

two first legs and two first elbows:

   ZGCr25Ni35Nb, ZGCr28Ni48W5, HK40, HT, HU, HH, 22H, More1, More2, KHR35H

two last legs and last elbow:

   HPNb, ZG40Cr25Ni20Si2

support: GX40Cr25Ni20

flanges: SGC25

   

Process

   

Legs is centrifugal casted and machined subsequently.

Elbows will be made by static casting or precision casting.

Support be made by precision casting.

Flange will be forged, welded and machined according to relevant drawings.

   

Property

   

characteristic of heat resistance and excellent creep srtength

   

Welding consumables

   

Similar to or higher than base material

or as per the buyer's requirements

   

Inspection

   

The most generally used methods of testing given below: 
Chemical analysis by Spectrometer 
Mechanical tests in Normal and High temperature. 
Ultrasonic, X-ray, Dye Penetrant Test. 
Boroscope; Eddy current testing; Microscope ; Pressure tests.

   

Application

   

1. heat resistant alloy radiant tubes are mainly used

   in petrochemical, metallurgary, steel and heat resistant industries.

2. corrosion resistant alloy radiant tubes are used

   in pulp and paper, chemical and other petrochemical industries.

3. super-alloys radiant tubes are

   used in high strength, carburization resistance industry.

   

Working temperature

   

depending on the materials (max 1250°C)

   

 

 

Taking energy efficiency and NOx emissions into consideration, the W shaped radiant tube and U shaped 

RT is more efficient and reliable. At the current energy price level, additional expenses for more efficient 

radiant tube systems can be recovered in a few years. Including the other advantages, such as increased 

production, less downtime, temperature uniformity, flame safety and better tube life time,  the payback 

period for these systems can be reduced considerably.
