Description
Technical field
The invention belongs to pipe technology fields, more particularly to a kind of pipeline reparation destroyed for drilling hole of oil stolen pipe cap
Special equipment.
Background technique
In recent years, the yield of petroleum increasingly increases, and the petroleum pipeline construction of long range is also constantly in rising trend therewith.
Country's petroleum pipeline mileage is long at present, is driven by economic interests, and criminal is stolen by the way of punching on petroleum pipeline
Oil product therefrom obtains economic interests, therefore can find in petroleum pipeline routine inspection the pipe that drilling hole of oil stolen is retained on pipeline
Cap, from the point of view of making a general survey of national oil pipeline, almost all of oil pipeline all none avoid.
The presence of the pipe cap of these drilling hole of oil stolen not only makes the property of country have the possibility for continuing to sustain a great loss, but also
Also will cause Oil spills, not only pollute environment, be easier to that some safety accidents occur, directly affect pipeline safety coefficient and
The life and property safety of the people.The generation of such thing in order to prevent, the mode generallyd use are to remove it, still
It is also possible to will lead to pipeline breakage during removal the risks such as even to explode, therefore retained particular for drilling hole of oil stolen
Pipe cap develops the special-shaped oversleeve of full packet.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of special-shaped oversleeve of full packet, mainly for exploitation one
Kind does not need to remove drilling hole of oil stolen pipe cap, easy to operate, saving material, device easy for construction and high degree of safety, is only punching
One protective cover of stolen pipe cap outer mask just can effectively solve pipeline, and there are various risk problems caused by drilling hole of oil stolen pipe cap.
The technical solution adopted by the invention is as follows:
A kind of special-shaped oversleeve of full packet, including upper guard board, lower backplate and gasket；The upper guard board covers on the pipe cap of drilling hole of oil stolen,
The pipe cap of pipeline and drilling hole of oil stolen is surrounded package with lower backplate in the lower part of pipeline, upper guard board by lower protection plate cover；Two gaskets point
It is not placed in the gap between upper guard board and lower backplate, is welded using cross weld；The side ring and pipeline that upper guard board and lower backplate are formed
Between carry out circumferential boxing seam welding, inside drilling hole of oil stolen hat cover, while integral solder exists last entire special-shaped oversleeve
On pipeline.
Further, the upper guard board includes end socket, branch pipe and arc plate from top to bottom, this three parts is weldingly connected.
Further, the arc plate is arcuate structure, is connected with branch pipe lower end, the diameter of arc plate and the diameter of pipeline
Match.
Further, the branch pipe is columnar structured, and upper end end face is that annular is weldingly connected with end socket, and lower end surface is
Irregular shape is weldingly connected with arc plate；The height of branch pipe upper surface to lower end surface most proximal end is greater than the height of the pipe cap of drilling hole of oil stolen
Degree, the diameter of branch pipe are determined according to the diameter of the pipe cap of drilling hole of oil stolen.
Further, the lower backplate cross section is semicircle, and radian is consistent with the radian of pipeline, diameter and pipeline it is straight
Diameter matching.
Pipeline, which checks, measures the report of pipe cap size superior after staff has found drilling hole of oil stolen pipe cap at the scene, then root
The special-shaped oversleeve of full packet is drawn according to size design, and is produced and processed, discovery drilling hole of oil stolen pipe cap scene is transported to and is assembled.
Advantages and advantages of the invention:
Advantages and advantages of the invention are easy for construction, quick, low costs, convenient transportation, are hardly damaged in transportational process,
Drilling hole of oil stolen event on pipeline is effectively reduced to continue to occur, mitigation national wealth loss significantly；Avoid drilling hole of oil stolen pipe cap
The risks such as damaged, explosion of pipeline caused by risk caused by damaged on pipeline, leakage etc. and removal drilling hole of oil stolen pipe cap.

Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
Embodiment
As shown in Figure 1-3, a kind of special-shaped oversleeve of full packet, including upper guard board 3, lower backplate 4 and gasket 5；The upper guard board 3 covers
On the pipe cap 2 of drilling hole of oil stolen, lower backplate 4 covers on the lower part of pipeline 1, upper guard board 3 and lower backplate 4 for pipeline 1 and drilling hole of oil stolen
Pipe cap 2 surround package；Gasket 5 is respectively placed in the gap between upper guard board 3 and lower backplate 4, is welded using cross weld；Upper guard board
Circumferential boxing seam welding is carried out between 3 and the side ring and pipeline 1 of the formation of lower backplate 4, last entire abnormal shape oversleeve is drilling hole of oil stolen
Cap 2 covers on the inside, while integral solder is on pipeline；The quantity of the gasket 5 can need to be increased and decreased according to assembled in situ.
4 cross section of lower backplate is semicircle, and radian is consistent with the radian of pipeline 1, the diameter matches of diameter and pipeline 1.
As shown in figure 4, the upper guard board 3 includes end socket 6, branch pipe 7 and arc plate 8 from top to bottom, this three parts is weldingly connected；
