Further, filler is equipped with inside the separation layer of the utility model.
Further, filler is equipped with inside the pipeline at the separation layer place of the utility model.It is set inside at the branch pipe
When setting filler, orifice plate setting two up and down.
Further, the oil transfer line of the utility model is the straight tube of unified internal diameter.Cancel the reducer of traditional oil transfer line, it will
The oil transfer line of traditional U-shaped is changed into straight tube, can be effectively reduced fatigue tendency and standing wave danger at traditional oil transfer line structural mutation
Evil reduces hydrogen damage.
Further, the both ends of the concetrated pipe of the utility model are equipped with hard support.Axial direction of the hard support to offsetting additional
Shock loading.
The branch pipe of the utility model and the type of attachment of concetrated pipe are butt weld, are sewed with than traditional fillet welding and greatly change
It is kind.
The method of the utility model is applicable not only to oil refining hydrogen manufacturing conversion furnace oil transfer line and concetrated pipe, is applied equally to pig
Tail pipe, propylene dehydrogenation, dehydrogenation of isobutane etc. other face the chemical plant installations pipeline of hydrogen damage.Use the pipeline of the utility model
Has the advantages that long service life, not easy to crack.
