Abstract

The utility model discloses a seamless butt-joint structure of petroleum pipelines. The seamless butt-joint structure of the petroleum pipelines comprises an inner embedded pipe, an outer sleeve pipe and two pipe end structures, wherein the two pipe end structures are in butt joint through the inner embedded pipe and are fixed through the outer sleeve pipe, outer conical surfaces are arranged at the two ends of the inner embedded pipe, inner conical surfaces are correspondingly arranged on both pipe end structures, the inner diameter of the inner embedded pipe is equal to that of the pipe end structures, threads are arranged on the outer portions of the pipe end structures, and the outer sleeve pipe is connected with the two pipe end structures through the threads. According to the seamless butt-joint structure of the petroleum pipelines, through the design of the inner embedded pipe, the outer sleeve pipe and the two pipe end structures, seamless butt-joint can be achieved, stress balancing and stability are also taken into consideration, therefore, perfect butt-joint is made to be achieved between two petroleum pipelines, and the effect that the butt-joint structure has a long service life is ensured.

Description

A kind of petroleum pipeline slitless connection structure
Technical field
The utility model relates to a kind of petroleum pipeline slitless connection structure, belongs to the petroleum pipeline technical field.
Background technique
Adopt the petroleum pipeline transfer oil, be not easy to have controlled joint technique in the process of petroleum pipeline docking, bring certain damping so just easily for oil in the process that flows, affect the flow velocity (transporting velocity) of oil.And meanwhile, also need stability and the stress equilibrium of pipeline docking are considered, so in the process of design and construction, the pipeline docking technique is a great difficult problem that faces.How designing and a kind ofly can realize slitless connection, and can satisfy simultaneously good stability and the good pipe joint technology of stress equilibrium, is the utility model technical issues that need to address.
The model utility content
In order to realize slitless connection, and can satisfy simultaneously good stability and the good petroleum pipeline docking problem of stress equilibrium, the utility model provides a kind of petroleum pipeline slitless connection structure.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of petroleum pipeline slitless connection structure, comprise embedded pipe, outer sleeve and two pipe end constructions, dock by described embedded pipe between two pipe end constructions, and fix with outer sleeve, the two ends of described embedded pipe have male cone (strobilus masculinus), and corresponding are provided with inner conical surface on each described pipe end constructions, and the internal diameter of described embedded pipe equates with the internal diameter of described pipe end constructions, the outside of described pipe end constructions has screw thread, and described outer sleeve is connected with two pipe end constructions by screw thread.
The middle part of described outer sleeve inner wall is provided with annular boss, and dock with two pipe end constructions respectively at the two ends of described annular boss, and the internal diameter of described annular boss is greater than the external diameter of described embedded pipe.
The length of described outer sleeve is more than the twice of described embedded length of tube.
A kind of petroleum pipeline slitless connection structure described in the utility model, design by embedded pipe, outer sleeve and two pipe end constructions, can realize slitless connection, and taken into account simultaneously considering of stress equilibrium and stability, make and realize perfectly docking between two petroleum pipelines, guarantee that linkage structure has permanent working life.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is a kind of structural drawing of petroleum pipeline slitless connection structure.
In figure: 1, embedded pipe; 2, outer sleeve; 3 pipe end constructions.
Embodiment
as shown in Figure 1, the described a kind of petroleum pipeline slitless connection structure of the utility model embodiment, comprise embedded pipe 1, outer sleeve 2 and two pipe end constructions 3, dock by described embedded pipe 1 between two pipe end constructions 3, and fixing with outer sleeve 2, the two ends of described embedded pipe 1 have male cone (strobilus masculinus), and corresponding is provided with inner conical surface on each described pipe end constructions 3, the internal diameter of described embedded pipe 1 equates with the internal diameter of described pipe end constructions 3, and be provided with the annular table terrace in the inboard of described inner conical surface, the radial width of described annular table terrace equals the thickness of the end of described embedded pipe 1, the outside of described pipe end constructions 3 has screw thread, described outer sleeve 2 is connected with two pipe end constructions by screw thread.
The middle part of described outer sleeve 2 inwalls is provided with annular boss, and dock with two pipe end constructions respectively at the two ends of described annular boss, and the internal diameter of described annular boss is greater than the external diameter of described embedded pipe.
The length of described outer sleeve 2 is more than the twice of described embedded pipe 1 length, guarantees that with this join domain of outer sleeve covers the stress area of described embedded pipe 1.
A kind of petroleum pipeline slitless connection structure described in the utility model, design by embedded pipe, outer sleeve and two pipe end constructions, can realize slitless connection, and taken into account simultaneously considering of stress equilibrium and stability, make and realize perfectly docking between two petroleum pipelines, guarantee that linkage structure has permanent working life.
It is to be noted; design of the present utility model is not limited only to above embodiment; any further improvement and distortion on the utility model design basis; the protection domain that all should belong to the utility model design; anyone permits without the obligee, all can not arbitrarily implement the design proposal of this patent.
