Abstract
The utility model discloses a kind of petroleum pipeline pipe nipple, including straight tube body, the straight inboard wall of tube body is provided with axial projections, and center line of the projection along straight tube body is set for spiral.The utility model will set projection on the inwall of pipe nipple, and be set around axis spiral so that is tangentially flowed by the fluid of pipe nipple, increases turbulivity, reduces adhesion.
Description
Technical field
Pipe fitting technical field is the utility model is related to, especially a kind of petroleum pipeline pipe nipple.
Background technology
Tubing nipple is the mechanical part that oil pipe connects in oil development, is mainly used in the connection of oil pipe.Tubing nipple rises
To connected pipes, tension is born, lifts the effect such as oil pipe, sealing oil pipe thread.Tubing nipple is exactly one section of short oil pipe, and oil pipe
Compare, simply length is different, and others have the same.Length has：0.25m, 0.5m, 1m, 1.5m etc., for assembling downhole pipe
Post.
Utility model content
The utility model in view of the shortcomings of the prior art, proposes a kind of petroleum pipeline pipe nipple, clever structure, and connectivity is good.
In order to realize above-mentioned purpose of utility model, the utility model provides following technical scheme：A kind of petroleum pipeline pipe nipple, bag
Straight tube body is included, the straight inboard wall of tube body is provided with axial projections, and center line of the projection along straight tube body is set for spiral.
Further, the projection is provided with least two, is evenly arranged on straight inboard wall of tube body.
Further, the surface of the projection is excessive cambered surface.
Compared with prior art, the utility model has advantages below：Will projection be set on the inwall of pipe nipple, and around axis
Spiral is set so that is tangentially flowed by the fluid of pipe nipple, increases turbulivity, reduces adhesion.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of the utility model petroleum pipeline pipe nipple.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings, the description of this part be only it is exemplary and explanatory,
There should not be any restriction effect to the scope of protection of the utility model.
As shown in figure 1, a kind of petroleum pipeline pipe nipple, including straight tube body 1, the inwall of straight tube body 1 are provided with axial projections 11, this is prominent
11 are played to set for spiral along the center line of straight tube body 1.
During by the pipe nipple, flowing through the oil of pipe nipple can be guided by projection 11, and rotating flow is made in the axial direction along straight tube body 1
It is dynamic, so as to change the single flow direction of fluid, turbulivity is added, reduces the blocking in pipe nipple.
The projection 11 is provided with least two, is evenly arranged on the inwall of straight tube body 1.The surface of the projection 11 is excessive arc
Face, reduce adhesive.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
