high quality U type radiant tube

Radiant Heater Tube U-type radiant tube:used for continuous annealing, galvanizing line of vertical annealing furnace. In nitrogen and hydrogen protection atmosphere, burning of natural gas or coke oven gas inside the tube heat the strip steel from room temperature to 750-950℃quickly and evenly through the outer tube radiation heat transfer for the annealing treatment. The straight tube sections are centrifugal castings, and the tube fittings are static castings. Best Radiant Tube Heaters Material:ZG45Ni48Cr28W5Si2, MORE1, MORE2
