Description
Technical field
It the utility model is related to pressure vessel field, the strengthening of welded seam structure of more particularly to a kind of composite board equipment.
Background technology
Titanium or titanium alloy material has many features：Density is small, and tensile strength is high, and specific strength is big, resistance in Oxidant
Corrosion can be good.So anti-corrosion pressure vessel often makes of titanium-steel composite board, but titanium can not pass through welding method and steel at present
Obtain having and meet being directly connected to for intensity requirement.
Therefore, the processing method of titanium-steel composite board pressure vessel and equipment commissure is typically：By the way that weld edge titanium is covered
Layer carries out the welding and heat treatment of basic unit's carbon steel after being partially stripped, weld seam position lining titanium backing plate after to be welded and heat treatment,
Both sides angle welding is covered to realize the sealing of internal titanium by titanium cover plate again, passes through air-tight test or helium leak test afterwards
The methods of check the quality of titanium weld seam and sealing property.To be hunted leak more effectively, exactly, while put into for post facility
Leak point is more rapidly and correctly found after use under the leak case being likely to occur, generally weld seam in equipment is divided into multiple
Relatively independent cavity processing, and each cavity both ends are by setting leak hunting aperture to be checked.But due to dividing chamber position lid
Plate attachment weld with equipment constantly makes because assembling and the limitation of welding sequence and structure can only carry out surface penetration Non-Destructive Testing
With, cause regional area corrosion etc. reason, divide chamber position cover plate attachment weld, the girth joint of especially basic unit is connected with longitudinal seam
The cover plate attachment weld at place is likely to the leakage hidden danger as the later stage.
Thus, the leakage hidden danger of composite board equipment weld seam how is eliminated, further increasing the security of composite board equipment is
Urgent problem at present.
The content of the invention
The purpose of this utility model is the strengthening of welded seam structure for providing a kind of composite board equipment so that composite board equipment
Weld seam does not have the leakage hidden danger in later stage, further improves the security of equipment.
In order to solve the above technical problems, embodiment of the present utility model provides a kind of strengthening of welded seam of composite board equipment
Structure, the composite board equipment include the coating that is bonded with the basic unit of basic unit, included in the basic unit the first weld seam, with it is described

In addition, second bed course is spliced by N block backing plates, N is the natural number more than or equal to 3, and any one piece is padded
Plate and its with the junctions of other backing plates in the overlay area of the protection board, first cover plate and second cover plate
Junction on this backing plate, and across this backing plate.The junction of backing plate is mutually not in contact with each other with the junction of cover plate, enhancing weldering
The security of seam.
In addition, leak hunting aperture is opened up on first bed course and second bed course respectively, the leak detection on first bed course
First weld seam is run through in hole, and the leak hunting aperture on second bed course runs through second weld seam, and the first weld seam and second are welded
Hunted leak at seam, ensure the weldquality of the first weld seam and the second weld seam.
In addition, the first weld seam of the basic unit and second commissure, which open up, accommodates first bed course and described second
The groove of bed course, first bed course and the second bed course are positioned in the groove.First bed course, the second bed course are by the weldering of basic unit
Seam covers more tight, effectively increases the security of commissure.
In addition, in the region of protection board covering, the extension of first cover plate and second cover plate point
Position not with coating welding forms two weld seams being parallel to each other.The shape and structure of protection board needed for this structure is more
To be simple, it is easy to manufacture.
In addition, two weld seams being parallel to each other are located at the centre position of the protection board, make this two parallel welderings
Sew and preferably protect, strengthen security.
In addition, the junction of first cover plate and second cover plate is located at the centre position of the protection board, make the
The junction of one cover plate and the second cover plate preferably protects, and strengthens security.
