Product Description
The main products of Qingdao Hexin Machinery Co., Ltd.  include:  
U radiant tubes, W radiant tubes, Straight radiant tubes, Electricity radiant tubes, Special radiant t
ubes. Ethylene cracking furnace, furnace tube, reformer furnace tube, and so on.
Qingdao Hexin Machinery Co., Ltd. offer custom engineering and production: Bung assemblies,flanges,reducers, return bends, centrifugal cast tubes, and tube hangers, assembled or individual parts.

The W-tupe radiant tube are usually used for continuous annealing line and galvanizing line vertical annealing furnace,Under the hydrogen nitrogen protective environment, and in order to avoid fuel combustion products contact with the workpiece, allows the fuel combustion procedure to carry out in the radiant tube, 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 900ºCquickly from the normal temperature,and make annealing treatment to strip steel.
straight pipe adopt centrifugal casting technology, liquid steel casted into various types of  tube blank under the effort of centrifugal force, according to boring internal hole with boring mill,machining and welding groove with lathe, precision casting for the elbow,after inspection,
Welding and assembly straight pipe and elbow by argon-arc welding according to the drawing. Commonly used material is ZG40Cr25Ni20Si2, ZG40Ni35Cr25Nb, ZG45Ni48Cr28W5Si2,1.4848,1.4852,2.4879etc. NDT tests are strictly carried out, so that to make sure the offered radiant tube have long usage life.
Some regular data about W radiant tubes: 
Range of Diameter: 60-2400mm 
Max. Length: 7000mm 
Min. wall thickness: 4mm 
Casting Tolerance: ±1mm 
Machining Toleracne: ±0.05mm
