Description
Technical field
The utility model belongs to the construction field of helix tube, and in particular to a kind of soldering opening of helix tube.
Background technology
In heating, in petroleum and petrochemical industry, the conveyance conduit corrosion of steel is extremely serious, in order to prevent or slows down or early rotten
Erosion, improves the service life of pipeline, generally adds coating layer and lining to the inner wall of steel pipe.And for the interface of pipeline, one
As be attached using the more mature welding manner of economic and reliable, technology.Soldering opening is difficult after construction, in the inside of interface
Preservative treatment is carried out, the high temperature of welding can also destroy coating and lining around welding, so that coating or lining is failed, lose guarantor
The function of shield, then weld can be corroded and make its weakness, cause to perforate or burst apart, to the service life structure of whole pipeline
At potential hidden danger, the lives and properties of environment and resident to pipeline also constitute threat.
Invention content
In view of the above technical problems, to make up the deficiencies in the prior art, the utility model proposes a kind of welderings of helix tube
Interface, the interface is easy to use, simple in structure and solve the problems, such as weld bond corrosion.
To achieve the above object, the utility model adopts the following technical solution, the utility model include the ends pipe joint A,
The ends pipe joint B, the ends pipe joint A are welding with the ends pipe joint B, and the ends the pipe joint A are convex configuration, convex configuration
The tube wall of convex front end be equipped with seal groove and the sealing ring that matches with seal groove, convex root is equipped with annular groove, convex
The outside of shape root is equipped with protective layer, and the ends pipe joint B are concave configuration.
Preferably, the protective layer is made of refractory insulating layer, corrosion-resistant coating.
Preferably, the quantity of the seal groove is multiple, and the quantity of sealing ring is the quantity of one to less than seal groove
Any number.
Further, the ends the pipe joint A and the ends pipe joint B inner wall are equipped with erosion resistant coating, and erosion resistant coating is coating or lining
In.
The utility model is characterized in that：
It is welded using existing, more mature welding procedure, is not needed other ancillary equipments；Use refractory heat-insulating
The protective layer that layer, corrosion-resistant coating are constituted plays the role of protection to the coating or lining of inner wall of the pipe；It is effective using sealing ring
Prevent the meson of conveying from corroding to weld bond；It is easy to use, construction is simple.
The utility model compared with prior art, manufacture be easy, construction is simple, it is at low cost, have wide range of applications, anticorrosion
Effect is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram at the ends pipe joint A of the utility model；
In figure：The ends 1- pipe joint A, the ends 2- pipe joint B, 3- protective layers, 4- seal grooves, 5- erosion resistant coatings, 6- sealing rings.
Specific implementation mode
The utility model is further explained below in conjunction with specific embodiment, but does not limit to this practicality
It is novel, structure, ratio, size depicted in Figure of description etc., only to coordinate the revealed content of specification, for ripe
The personage for knowing this technology understands and reads, and is not limited to the enforceable qualifications of the utility model, therefore does not have technically
Essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size can be produced not influencing the utility model
Under raw effect and the purpose that can reach, the range that can cover in the revealed technology contents of the utility model should all be still fallen
It is interior.Meanwhile cited such as "upper", "lower", "front", "rear", " centre " term in this specification, it is merely convenient to describe
It is illustrated, rather than to limit the enforceable range of the utility model, relativeness is altered or modified, skill is being changed without essence
It is held in art, when being also considered as the enforceable scope of the utility model.
As shown in Figure 1, a kind of soldering opening of helix tube, this interface are primarily directed to connecing by electric welding connection pipeline
Mouthful, the inner wall of the conveyance conduit of steel can all be coated with etch-proof coating at present, but after the joint weld of conveyance conduit again into
Row preservative treatment is more difficult, and the coating around interface during the welding process because high temperature also can deterioration failure, this interface
Including the ends pipe joint A 1, the ends pipe joint B 2, the ends pipe joint A 1 are convex configuration, and the convex front end of convex configuration is equipped with close
Sealing groove 4 is equipped with high temperature resistant, etch-proof sealing ring 6 on seal groove 4, and the quantity of seal groove 4 is multiple, the quantity of sealing ring 6
For one to less than any number of the quantity of seal groove 4, prevent the meson conveyed in pipeline from penetrating into weldering by sealing ring 6
Mouthful, the root of convex can extend to the inside formation groove at the ends pipe joint A 1, and the outside of convex root is equipped with by refractory heat-insulating
The protective layer 3 that layer, corrosion-resistant coating are constituted, protective layer 3 can effectively prevent the high temperature pipe joint because being generated when welding
Erosion resistant coating 5, the ends pipe joint B are concave configuration, and the inside of interface is corroded in order to prevent, the ends pipe joint A 1 and pipe joint
2 inner wall of the ends B is equipped with erosion resistant coating 5, and erosion resistant coating 5 is coating or lining.
Specific form of construction work, since the meson of conveyance conduit conveying is different, erosion resistant coating that the inner wall of conveyance conduit uses
Also can be different, the quantity and material of the structure and sealing ring of protective layer are confirmed according to different conveying mesons and erosion resistant coating, are chosen
And stretch at the ends pipe joint A in the ends pipe joint B after installing protective layer and sealing ring, pass through electric welding after being installed in place
?.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
