React the high-temperature service of hydrogen making.Oil transfer line, concetrated pipe, pigtail are the matched pipelines used, and hydrogen manufacturing conversion furnace makes
After a period of time, above-mentioned pipeline cracks frequent occurrence, and service life is short, and less serious case can force oil refining apparatus to be stopped work, and severe one can draw
Ignition calamity causes huge economic loss.
Invention content
It is an object of the invention to solve the oil transfer line of hydrogen manufacturing conversion furnace and concetrated pipe there are easy to crack, service life is short
Defect, a kind of method for preventing pipeline hydrogen damage and oil refining hydrogen manufacturing conversion furnace oil transfer line and set using this method are provided
Pipe, after the present invention, pipeline hydrogen damage is small, not easy to crack, safety, and service life is long.
The present invention is achieved by the following technical solution：
I.e. a kind of method preventing pipeline hydrogen damage, it is characterised in that the hollow of buffer action has been set in the inner wall of pipeline
Separation layer, the end of pipeline is arranged the filler worked as a buffer, the orifice plate of support separation layer is equipped in pipeline.
By applicant's the study found that the basic reason of traditional hydrogen manufacturing conversion furnace oil transfer line and concetrated pipe cracking is hydrogen loss
Wound, this is because：
1. there is hydrogen (especially atomic state or the hydrogen of ionic state) in material；
2. at structural mutation (reducing, elbow, trepanning, end)：
1. there are additional alternating loads to lead to fatigue；
2. there are standing waves, first, having encouraged fatigue；Second is that hydrogen is made to be more easy to penetrate into metal, hydrogen damage is aggravated.
The separation layer of the present invention is hollow bushing pipe or bushing, plays buffer action, can effectively reduce hydrogen to pipeline
Damage.
The filler of the present invention works as a buffer, the fatigue that can be effectively reduced the additional load suffered by pipeline and thereby result in
Tendency, reduces the harm of hydrogen damage.
Further, separation layer of the invention is preferably but not limited to be arranged at the structural mutation of pipeline.At structural mutation
Reducing, elbow, trepanning, the end etc. refered in particular to but be not limited to pipeline.
Further, pipeline of the invention is internally provided with the orifice plate of support separation layer.
The orifice plate of the present invention plays fixed separation layer and filler, while not influencing the flowing of material again.
Further, filler is equipped in separation layer of the invention；
Further, the pipeline at separation layer of the invention place is internally provided with filler.
A kind of oil refining hydrogen manufacturing conversion furnace oil transfer line and concetrated pipe using the above method, including oil transfer line and concetrated pipe, collection
The side for closing pipe is connect with branch pipe, it is characterised in that the inner wall of the pipe of oil transfer line is equipped with hollow separation layer, the end of concetrated pipe
Equipped with filler, branch pipe wall and branch pipe and the inner wall of concetrated pipe junction are equipped with hollow separation layer.
The oil transfer line of the present invention refers to the connecting pipe between convection section and radiant section manifold inlet (i.e. the big end of reducing).
It is at structural mutation that separation layer place, which is arranged,.
Further, the orifice plate of support separation layer is equipped in oil transfer line of the invention, in concetrated pipe, in branch pipe.As
Hole Board position is preferred：The arrival end of oil transfer line, outlet end gather and are all provided with abacus in the middle part of pipe end and branch pipe.
Further, separation layer of the invention is internally provided with filler.
Further, it is equipped with filler inside the pipeline at separation layer of the invention place.Inside setting is filled out at branch pipe
When material, orifice plate setting two up and down.
Further, oil transfer line of the invention is the straight tube of unified internal diameter.The reducer for cancelling traditional oil transfer line, will be traditional
The oil transfer line of U-shaped is changed into straight tube, can effectively reduce the fatigue tendency at traditional oil transfer line structural mutation and standing wave harm, subtract
Small hydrogen damage.
Further, the both ends of concetrated pipe of the invention are equipped with hard support.The hard axial impact supported to offsetting additional
Load.
The branch pipe of the present invention and the type of attachment of concetrated pipe are butt weld, and great improvement is sewed with than traditional fillet welding.
The method of the present invention is applicable not only to oil refining hydrogen manufacturing conversion furnace oil transfer line and concetrated pipe, is applied equally to pigtail
Pipe, propylene dehydrogenation, dehydrogenation of isobutane etc. other face the chemical plant installations pipeline of hydrogen damage.Being had using the pipeline of the present invention is made
With long lifespan, advantage not easy to crack.
