Between, the first welding rod, the second welding rod, the 3rd welding rod and the 4th welding rod use the mode of hot melt to be sealedly attached to outer tube
And between pipeline.
The two ends of outer tube are respectively welded on two segment pipes, again weld between welding groove and pipeline, thus
Realize multi-pass welding seam, it is ensured that pipeline distance traction, stretching when two pipelines between welding fastness, it is to avoid routine can only
Carry out at outer tube two ends welding and easily produce the unsteady problem of welding.
For the firmness that outer tube is overall, the pipe wall position between described welding groove two ends is different.
The first welding rod, the second welding rod, the 3rd welding rod and the 4th welding rod that arrange effectively ensure that welding
Air-tightness, has the positive effect of reality to conduit for gas, running water pipeline etc., it is to avoid conveying material (as running water,
Natural gas) reveal at two pipeline weldings.
Use outer tube welding, it is to avoid directly welding of two pipeline junctions, two pipeline junctions have certain interval, make
Obtain pipeline and there is certain crooking ability.Meanwhile, the first welding rod, the second welding rod, the 3rd welding rod and the 4th welding rod set
Putting at two pipeline junctions, when pipeline bends at outer tube, welding rod can play buffering between pipeline and outer tube
Effect, it is to avoid abrasion and rigid contact, the weld seam of indirect protection rigidity.
In order to between the first welding rod and the second welding rod, and airtight between the 3rd welding rod and the 4th welding rod
Property detect, the tube wall of outer tube is provided with the first detection hole, second detection hole, first detection hole be arranged on first melt
Connecing between bar and the second welding rod, the second detection hole is arranged between the 3rd welding rod and the 4th welding rod.When from the first detection
Hole, the second detection hole be when being passed through gas, check the flow of gas just can between the first welding rod and the second welding rod, and
Air-tightness between 3rd welding rod and the 4th welding rod detects.
The utility model simple in construction, the setting of outer sleeve structure, it is ensured that two pipelines weldering when the traction of distance, stretching
The firmness connecing and tightness.
Brief description
Fig. 1 is Welding Structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of outer tube.
Detailed description of the invention
With detailed description of the invention, the utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of trombone slide engineering method pipeline welding structure, including outside at the pipe joint of two pipelines 1,2
Sleeve pipe 3, the two ends of described outer tube 3 are provided with the welding groove 9 of one or more, three (sides) as shown in Figure 1, and described
Tube wall 12 position between welding groove 9 two ends is different, the beneficially firmness of outer tube 3 entirety.Described welding groove 9 is at outer tube
