radiant heater tubes by Qingdao Hexin Machinery Co.,Ltd.
radiant heater tubes
Our company has many years success experience for the production of radiant tube, , the main material of radiant tube is high nickel chromium alloy cast steel, such as 2.4879, 1.4852, ZG45Ni48Cr28W5Si2, MORE1, MORE2, flange through forging and machining, maximum use temperature up to 1200 degrees, can work under 800 and 1200 ℃.
The U-tupe radiant tube are usually used for continuous annealing line and galvanizing line vertical annealing furnace, under the hydrogen nitrogen protective environment, Tube is provided by natural gas or coke oven gas combustion heat energy,and radiate the heat to workpiece through tube wall, By way of radiation heat transfer outside tube,and make the strip steel running at a constant speed heated to 900℃quickly from the normal temperature, and make annealing treatment to strip steel.straight pipe adopt centrifugal casting as casting, precision casting for the elbow,the material is high nickel chromium alloy cast steel, such as 2.4879，1.4852，ZG45Ni48Cr28W5Si2、MORE1、MORE2.
These can be with or without flanges, bellows, collars, and/or insulation already installed.
