Abstract
The utility model discloses a kind of double-deck welded tube with alternating expression weld seam, comprise welded tube body, described welded tube body forms weld seam after pressurizing unit extruding, the both sides of described weld seam are equipped with outward extending solder-bump, this weld flush is alternating expression on weld seam both sides and is arranged in order, and leaves welded gaps between the relative weld flush in weld seam both sides; This external one deck composite bed that is also coated with of described welded tube, the first half of described composite bed is also provided with two symmetrical grooves.Of the present utility model reasonable in design, by the position that the weld seam of alternating expression can very convenient tack weld is set, prevent weld seam deviation, and leave certain void and guarantee welding quality, the utility model is also provided with the intensity that steel copper composite bed has been strengthened welded tube.
Description
Technical field
The utility model relates to a kind of welded tube, specifically a kind of double-deck welded tube with alternating expression weld seam.
Background technology
Often there is such problem in welded tube, first, weld seam location is inaccurate in the process of welding after pressurizing unit extruding, when pushing due to welded tube, there is larger stress, after pressurizing unit extruding, the alignment that weld seam cannot be real, welding produces deviation, causes welding tube quality variation.Traditional welded tube is individual layer welded tube in addition, insufficient strength, and the scope of application is limited, and versatility is poor.
Again because the welded tube overwhelming majority is cylindrical welded tube; in installation car or unloading; conventionally adopt the mode of " pyramid " to freight; yet because columniform welded tube is very unstable; often can roll due to himself gravity or other reasons; although all focus on very much safety problem when turn-round, the too great Yi rolling of volume due to welded tube, still can cause security incident.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, and a kind of double-deck welded tube with alternating expression weld seam is provided.
The purpose of this utility model is the deficiency existing for prior art, a kind of double-deck welded tube with alternating expression weld seam is provided, comprise welded tube body, described welded tube body forms weld seam after pressurizing unit extruding, the both sides of described weld seam are equipped with outward extending solder-bump, this weld flush is alternating expression on weld seam both sides and is arranged in order, and leaves welded gaps between the relative weld flush in weld seam both sides; This external one deck composite bed that is also coated with of described welded tube, the first half of described composite bed is also provided with two symmetrical grooves, and the crossing angle in the center of circle of two grooves and welded tube body is 60 °, the Lower Half of described composite bed is provided with groove and is used in combination projection, and is also provided with horizontal some welding grooves between described composite bed and welded tube body; On the surface of described welded tube body, be also provided with the reinforcement radially welding along welded tube body.
As preferably, described groove and projection are groove and the projection of arc.
As preferably, described weld width is less than 2mm.
As preferably, described composite bed is steel copper composite bed.
As preferably, described welding groove is provided with 10 altogether, all and be arranged between composite bed and welded tube body.
Beneficial effect: of the present utility model reasonable in design, by the position that the weld seam of alternating expression can very convenient tack weld is set, prevent weld seam deviation, and leave certain void and guarantee welding quality, the utility model is also provided with the intensity that steel copper composite bed has been strengthened welded tube, its range of application is expanded, the more important thing is on steel copper composite bed and designed and be used in conjunction with each other groove and projection, in welded tube " pyramid " loading unloading process, the projection of adjacent welded tube and groove can be stuck, prevent that welded tube from rolling, the generation of minimizing accident.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the top view figure of alternating expression weld seam in the utility model;
Fig. 3 is groove of the present utility model and protruding use schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, the present embodiment is implemented take technical solutions of the utility model under prerequisite, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.
As shown in figures 1 and 3, a kind of double-deck welded tube with alternating expression weld seam, comprise welded tube body 1, described welded tube body 1 forms weld seam 2 after pressurizing unit extruding, the both sides of described weld seam 2 are equipped with outward extending solder-bump 3, this weld flush 3 is alternating expression on weld seam 2 both sides and is arranged in order, and leaves welded gaps 4 between the relative weld flush 3 in weld seam 2 both sides; The outer one deck composite bed 5 that is also coated with of described welded tube body 1, the first half of described composite bed 5 is also provided with two symmetrical grooves 6, and the crossing angle in two grooves 6 and the center of circle of welded tube body 1 is 60 °, the Lower Half of described composite bed 5 is provided with groove 6 and is used in combination projection 7, and between described composite bed 5 and welded tube body 1, is also provided with horizontal some welding grooves 8; On the surface of described welded tube body 1, be also provided with the reinforcement 5 radially welding along welded tube body 1; Described groove 6 and projection 7 are groove and the projection of arc.Described weld width is less than 2mm.Described composite bed 5 is steel copper composite bed.Described welding groove 8 is provided with 10 altogether, all and be arranged between composite bed and welded tube body 1.
In conjunction with Fig. 1 and Fig. 2, by the position that the weld seam of alternating expression can very convenient tack weld is set, prevent weld seam deviation, and leave certain void and guarantee welding quality, the utility model is also provided with the intensity that steel copper composite bed has been strengthened welded tube, and its range of application is expanded.
In conjunction with Fig. 3, the utility model has also designed and has been used in conjunction with each other groove and projection on steel copper composite bed, welded tube is in cargo handling process, cylinder design during due to welded tube, angle between the contact position of adjacent welded tube is identical, two grooves on each welded tube and the angle between two projections are 60 degree, projection and groove fit on the welded tube that each welded tube upper groove and projection can be adjacent are used, can be in welded tube " pyramid " loading unloading process, the projection of adjacent welded tube and groove can be stuck, prevent that welded tube from rolling, the generation of minimizing accident.
