Abstract
The invention discloses a petroleum sleeve coupling with a heat retaining property. The petroleum sleeve coupling with the heat retaining property comprises a sleeve body, the two ends of the sleeve body are connected to conical couplings, the sleeve body is provided with a first sleeve, the first sleeve and the sleeve body are connected in a threaded mode, a through-hole is formed in the sleeve body, an inner sleeve is arranged in the through-hole, and the inner wall of the inner sleeve is provided with a polyurethane insulating layer and an electric heating tube. According to the petroleum sleeve coupling with the heat retaining property, the electric heating tube and the insulating layer are arranged on the inner sleeve, it can be guaranteed that the coupling is not usable due to the influence of the temperature in the using process, particularly in winter, when the temperature reaches a certain degree, a controller controls the electric heating tube for heating, the insulating layer saves energy sources, and finally normal use of the overall device is effectively guaranteed.
Description
Technical field
The present invention relates to petroleum pipeline technical field, more particularly to a kind of coupling of petroleum casing pipe with heat insulating ability.
Background technology
It is well known that the box cupling for petroleum casing pipe is one kind in petroleum pipeline auxiliary equipment, it is widely used in oil
Exploitation field；Find in this box cupling use for petroleum casing pipe, due in cold winter, especially northern the Northeast
Often occur freezing or the neighbouring state (it is usually subzero 60 degrees Celsius to 30 degrees Celsius above freezing that oil freezes) for freezing,
So as to cause overall box cupling to use.
The content of the invention
In order to overcome the problem of existing technical deficiency, the present invention to provide a kind of coupling of petroleum casing pipe with heat insulating ability.
The technical scheme is that what is be achieved in that：A kind of coupling of petroleum casing pipe with heat insulating ability, including sleeve pipe master
Body, described sleeve pipe main body two ends are connected with the box cupling of cone, and described sleeve pipe main body is provided with the first sleeve, the first sleeve and sleeve pipe
It is threadedly coupled between main body, through hole is provided with described sleeve pipe main body, inner sleeve is set in through hole, the inner sleeve inside pipe wall is provided with firmly
Matter polyurethane insulation coating and electric heating tube.
Preferably, one layer of anticorrosion antiwear layer is additionally provided with outside the heat-insulation layer.
Preferably, the electric heating tube is connected with controller.
Present invention has the advantages that：Electric heating tube and heat-insulation layer are provided with inner sleeve in the present invention, can guarantee that box cupling exists
Especially winter will not cannot use because of the impact of temperature during use, when temperature reaches to a certain degree, controller control
Electric heater for heating processed, and heat-insulation layer energy save energy, have finally effectively ensured that single unit system is normally used.
Description of the drawings
Fig. 1 is the structural representation of coupling of petroleum casing pipe of the present invention with heat insulating ability；
Fig. 2 is a kind of sectional view of embodiment of inner sleeve of the present invention；
In figure：1 first sleeve, 2 inner sleeves, 3 casing main bodies, 4 box cuplings, 5 heat-insulation layers, 6 electric heating tubes.
Specific embodiment
In conjunction with the accompanying drawings and embodiments the present invention is described further.
As shown in figure 1, a kind of coupling of petroleum casing pipe with heat insulating ability, including casing main body, the two ends of described sleeve pipe main body 3
The box cupling 4 of cone is connected with, described sleeve pipe main body 3 is provided with the first sleeve 1, screw thread connects between the first sleeve 1 and casing main body 3
Connect, in described sleeve pipe main body 3 through hole is provided with, inner sleeve 2 is set in through hole, the inwall of the inner sleeve 2 is provided with hard polyaminoester guarantor
The electric heating tube 6 of warm layer 5.
In the present invention, one layer of anticorrosion antiwear layer is additionally provided with outside the heat-insulation layer, the anticorrosion antiwear layer has for plating tungsten
Non-ferrous metal coating.The electric heating tube is connected with controller, and controller is connected with control system, and temperature is set in the control system
Angle value, when ambient temperature reaches setting value, the pneumatic electric heating tube of control system transmitting signal controller is heated, and prevents from connecing
Hoop freezes.
Electric heating tube and heat-insulation layer are provided with inner sleeve in the present invention, box cupling especially winter in use is can guarantee that
It will not cannot be used because of the impact of temperature, when temperature reaches to a certain degree, controller control electric heater for heating, and protect
Warm layer energy save energy, has finally effectively ensured that single unit system is normally used.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that still can make
Various modifications and alterations are without departing from the spirit and scope of the present invention.Therefore, specification is considered as illustrative rather than limit
Property processed.
