Abstract
The utility model discloses a kind of petroleum pipeline thermal-insulating type pipe nipple, including straight tube body, the wall of the straight tube body is made up of successively internal layer, zone of heating, heat-insulation layer and enhancement layer, and internal layer middle part outside is provided with groove structure, and zone of heating is embedded in the groove；The full groove of heat-insulation layer filling, enhancement layer cladding heat-insulation layer.The utility model will set heating and insulation construction in the inwall of pipe nipple, when oil is by pipe nipple, obtain heat supplement, be not in lower the temperature and adhesion phenomenon, increase mobility, reduce adhesion.
Description
Technical field
The utility model is related to pipe fitting technical field, especially a kind of petroleum pipeline thermal-insulating type pipe nipple.
Background technology
Tubing nipple is the mechanical part of oil pipe connection in oil development, is mainly used in the connection of oil pipe.In petroleum transportation
In, tubing nipple plays connected pipes, and because pipe nipple is made of metal material mostly, thermal diffusivity is good, causes by pipe nipple
Oil easily occur viscosity reduction and blockage phenomenon.
Utility model content
The utility model in view of the shortcomings of the prior art, proposes a kind of petroleum pipeline thermal-insulating type pipe nipple, clever structure, heat insulating ability
It is good.
In order to realize above-mentioned utility model purpose, the utility model provides following technical scheme：A kind of petroleum pipeline thermal-insulating type
Pipe nipple, including straight tube body, the wall of the straight tube body are made up of successively internal layer, zone of heating, heat-insulation layer and enhancement layer, internal layer middle part outside
Groove structure is provided with, zone of heating is embedded in the groove；The full groove of heat-insulation layer filling, enhancement layer cladding heat-insulation layer.
Further, the zone of heating is electrical heating wire structure, and spiral winding is in a groove.
Further, each layer of straight tube body thickness ratio successively is not：Internal layer 1, heat-insulation layer 1.5 and enhancement layer 2.
Compared with prior art, the utility model has advantages below：Heating and insulation knot will be set in the inwall of pipe nipple
Structure, when oil is by pipe nipple, obtains heat supplement, is not in lower the temperature and adhesion phenomenon, increases mobility, reduces adhesion.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of the utility model petroleum pipeline thermal-insulating type pipe nipple.
Specific 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 protection domain of the present utility model.
As shown in figure 1, a kind of petroleum pipeline thermal-insulating type pipe nipple, including straight tube body, the wall of the straight tube body is by internal layer 1, zone of heating
2nd, heat-insulation layer 3 and enhancement layer 4 are constituted successively, and the middle part of internal layer 1 outside is provided with groove structure, and zone of heating 2 is embedded in the groove；Protect
The full groove of the filling of warm layer 3, the cladding heat-insulation layer 3 of enhancement layer 4.
When fluid passes through the pipe nipple, because zone of heating 2 provides heat, and under the effect of heat-insulation layer 3, heat transfer to oil
Fluid so that the oil for flowing through pipe nipple will not occur lowering the temperature and adhesion as traditional pipe nipple, but have promotion to flow to petroleum fluids
Effect of property, reduces the blocking in pipe nipple.
The zone of heating 2 is electrical heating wire structure, and spiral winding is in a groove；Each layer of straight tube body thickness ratio successively is other
For：Internal layer 1, heat-insulation layer 1.5 and enhancement layer 2, for the pipe nipple of connection provides corresponding intensity.
The 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 protection domain of the present utility model.
Claims (3)
1. a kind of petroleum pipeline thermal-insulating type pipe nipple, it is characterised in that：Including straight tube body, the wall of the straight tube body is by internal layer, zone of heating, guarantor
Warm layer and enhancement layer are constituted successively, and internal layer middle part outside is provided with groove structure, and zone of heating is embedded in the groove；Heat-insulation layer is filled
The full groove, enhancement layer cladding heat-insulation layer.
2. petroleum pipeline thermal-insulating type pipe nipple as claimed in claim 1, it is characterised in that：The zone of heating is electrical heating wire structure, spiral
Winding is in a groove.
