Description
Technical field
The invention belongs to petroleum pipeline technical field, more particularly to a kind of petroleum pipeline deferent box cupling structure.
Background technology
Usually produced using universal oil pipe in oilfield process, the crude oil extracted out from oil field passes through oil well pump quilt
During giving rise to ground, substantial amounts of heat passes through the part such as oil jacket ring, sleeve pipe and scatters and disappears in the earth formation, with inclined shaft quantity
Increase, eccentric wear phenomenon is serious, latter period of oilfield development, High water cut causes oil well corrosion and scaling, affect the normal production run of oil well,
Oil pipe connects insecure.
Content of the invention
It is contemplated that overcoming the defect of prior art, a kind of petroleum pipeline deferent box cupling structure being provided, there is highly versatile,
More reliable, the feature of working stability of safety.
In order to solve above-mentioned technical problem, the present invention provides technical scheme below：
A kind of petroleum pipeline deferent box cupling structure, including pipe box cupling, petroleum pipeline, petroleum pipeline includes steel interior conduit, steel Outer Tube, reinforcement
Rib, the socket of steel Outer Tube is arranged on outside steel interior conduit, is coated with the synthetic resin coated bed of material, steel Outer Tube and steel in steel interior conduit
It is provided with reinforcement rib, petroleum pipeline one end adds pipe box cupling, and pipe box cupling inwall is provided with internal lining pipe, outside pipe box cupling between interior conduit
Pressure transducer is installed in side, and pipe box cupling is connected with elbow.
Further, internal lining pipe is steel lining polyfluortetraethylene pipe or steel lining PTFE tube.
Further, described steel interior conduit and steel Outer Tube are not equal diameter pipe.
Compared with prior art, the present invention has following beneficial effect：
The present invention is applied to and is connected between the pipeline of different tube diameters, and highly versatile makees stone with synthesis numerical value anticorrosive coating
Oil-piping undercoating is the effective measures of inner wall anti-corrosive, and pipe box cupling installs pressure transducer, being capable of real-time detection petroleum pipeline
Pressure, safer, more reliable.
Brief description
Fig. 1 is the schematic diagram of petroleum pipeline deferent box cupling structure of the present invention.
Fig. 2 is the generalized section of petroleum pipeline deferent box cupling structure of the present invention.
Specific embodiment
