Abstract

Pipe collar, including pipe collar body are incubated the utility model discloses a kind of petroleum pipeline, the side wall of the pipe collar body is sequentially connected by internal layer, heating arrangement and heat-insulation layer to be constituted, and heat-insulation layer coats whole internal layer, and heating arrangement is covered on inner layer outer wall.The utility model is set in the wall of pipe collar side containing heating and insulation construction so that whole pipe collar is heated to the petroleum fluids flowed through, reduces the viscosity of oil, maintains the smoothness of whole pipeline transportation.

Description

Petroleum pipeline is incubated pipe collar

Technical field

The utility model is related to pipe fitting technical field, especially a kind of petroleum pipeline insulation pipe collar.

Background technology

Pipeline is that petroleum transportation is most economical, a kind of rational means of transportation.Company between pipeline crude oil, oil pipe It is typically to be attached using oil pipe pipe collar to connect mode, and oil pipe pipe collar has tubulose pipe collar body, and the two ends of pipe collar body have Internal thread is connected, during using oil pipe pipe collar connected pipes, internal thread is connected oil pipe pipe collar is screwed into externally threaded oil pipe It is interior, oil continuative transport pipeline is formed with this, the continuative transport of oil is realized.

Connection between tubing coupling of the prior art and oil pipe, simply oil pipe enter in pipe collar a part of, enter There is interval between two oil pipe ends of pipe collar；And because pipe collar is typically made using metal, heat transfer efficiency is high, by pipe collar Oil rapid heat dissipation, easily condenses and blocks.

Utility model content

The utility model in view of the shortcomings of the prior art, proposes a kind of petroleum pipeline insulation pipe collar, simple in construction, heat-insulating property It is good.

In order to realize above-mentioned utility model purpose, the utility model provides following technical scheme：A kind of petroleum pipeline insulating tube Hoop, including pipe collar body, the side wall of the pipe collar body is sequentially connected by internal layer, heating arrangement and heat-insulation layer to be constituted, heat-insulation layer bag Whole internal layer is covered, heating arrangement is covered on inner layer outer wall.

Further, inner layer outer wall is provided with groove structure, and the heating arrangements are located in the groove structure.

Further, the heating arrangement is electrical heating wire.

Compared with prior art, the utility model has advantages below：Set in the wall of pipe collar side containing heating and insulation knot Structure so that whole pipe collar is heated to the petroleum fluids flowed through, reduces the viscosity of oil, maintains the smooth of whole pipeline transportation The general character.

Brief description of the drawings

Fig. 1 is the structural representation that the utility model petroleum pipeline is incubated pipe collar.

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 insulation pipe collar, including pipe collar body, the side wall of the pipe collar body by internal layer 1 plus Heat structure 3 and heat-insulation layer 2 are sequentially connected composition, and heat-insulation layer 2 coats whole internal layer 1, and heating arrangement 3 is covered on the outer wall of internal layer 1.

Pipe collar body two ends inwall is provided with the female thread structure being connected with petroleum pipeline, because the petroleum pipeline of threaded connection is nothing Method covers pipe collar inner body wall, and adhesion occurs in the oil temperature reduction for causing pipe collar to conduct heat and flowing through pipe collar, along with herein Internal diameter changes, and easily blocks；And heating arrangement 3 is set up on pipe collar body, reach that heat oil glues the oil of adhesion Degree reduction, and avoid clogging.

To ensure that the heat that heating arrangement 3 is produced can be conducted to pipe collar, the outer wall of internal layer 1 is provided with groove structure, heater Structure 3 is electrical heating wire, is wound around in the groove structure；Heat-insulation layer 2 coats the outer wall of all internal layers 1.

Heat-insulation layer 2 can be made up of abrasive rubber material.

Described 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 (2)

1. a kind of petroleum pipeline is incubated pipe collar, including pipe collar body, it is characterised in that：The side wall of the pipe collar body is by internal layer, heating Structure and heat-insulation layer are sequentially connected composition, and heat-insulation layer coats whole internal layer, and heating arrangement is covered on inner layer outer wall；Inner layer outer wall Provided with groove structure, the heating arrangements are located in the groove structure.

2. petroleum pipeline as claimed in claim 1 is incubated pipe collar, it is characterised in that：The heating arrangement is electrical heating wire.
