Abstract

The utility model discloses an oil and gas pipe section isolating tool, and belongs to the field of pipeline replacement technologies required by leakage or corrosion of gathering and delivering pipelines. The oil and gas pipe section isolating tool is characterized in that a gas guide steel pipe handle is perpendicularly welded at the circle center of a circular iron cake; the other end of the gas guide steel pipe handle is connected with a gas guide hose; a hole is formed in the circle center of the circular iron cake, and the diameter of the hole is smaller than the outer diameter of the gas guide steel pipe handle; wet and large cloth is uniformly wound on the circumference of the circular iron cake, and grease is smeared on the wet and large cloth; external threads are arranged at the other end of the gas guide steel pipe handle, and an internal threaded plug is connected to the other end of the gas guide steel pipe handle. The oil and gas pipe section isolating tool has the advantages that when pipelines need to be replaced due to leakage or corrosion of the oil and gas gathering and delivering pipelines, flame operation can be carried out under certain special technological conditions, and the oil and gas pipe section isolating tool is convenient, quick and safe as compared with a 'grease wall'.

Description

A kind of oil gas pipeline section isolating tool

Technical field

The utility model relates to a kind of oil gas pipeline section isolating tool, belongs to the leakage of gathering line thorn or corrosion and must change the pipeline technology field.

Background technique

After the oil-gas gathering and transferring pipeline thorn leaks or corrodes, must speedily carry out rescue work while changing pipeline and all need to carry out on-the-spot fire operation, although the operation pipeline section has cut off the upstream and downstream flow process before getting angry, and emptying pressure release, if scene does not possess the pipeline purging condition, still have oil gas to residue in pipeline, very easily cause while getting angry and have a strong impact on operating personnel's personal safety by fire explosion.

Each oilfield treatments oil-gas gathering and transferring pipeline leaks because of thorn or corrosion replacing pipeline at present, while needing fire operation, all adopts " butter wall " is set, and carries out the oil gas isolation.But there is certain limitation in the method, under some particular cases, use " butter wall " can increase on foot operating personnel's workload and operation danger.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of oil gas pipeline section isolating tool.

A kind of oil gas pipeline section isolating tool, air guide steel pipe handle is vertically welded in circular discus circle centre position; The air guide steel pipe handle the other end connects soft air-guide pipe; The circle centre position of circular discus is porose, and aperture is less than the external diameter of air guide steel pipe handle; The wet large cloth of uniform winding on circular discus circumference, coating butter on wet large cloth; The air guide steel pipe handle the other end has outside thread, and the air guide steel pipe handle the other end connects the internal thread plug.

The length of soft air-guide pipe is between 5m～6m.

The utility model has the advantages that and a kind ofly leak or corrosion must change pipeline the time when oil-gas gathering and transferring pipeline thorn, get angry under some special process condition, " butter wall " more convenient, faster, safer oil gas pipeline section isolating tool.

Adopt technique scheme, be achieved as follows advantage:

1, the utility model fabricating cost is extremely cheap, for same internal diameter straight pipeline, can be used repeatedly, and utilization ratio is high;

2, near the straight pipe-line that has flange to connect pipeline fire operation place, distance is greater than 50cm, " butter wall " also can't effectively be set after taking flange apart, if utilize oil gas isolating tool of the present utility model very convenient, quick;

3, the utility model on-the-spot use more flexible: for emptying, release flow process just not in the situation of operation pipeline section, the utility model can remove the plug 6 of air guide steel pipe handle 2, with soft air-guide pipe 3, be connected, remaining oil gas in pipeline is caused several meters away, impel internal and external pressure balance, prevented from causing operation pipeline section and extraneous pressure reduction to increase because leaking in the flow process block valve, the situation that causes isolated failure, oil gas to leak occurs, and has guaranteed the Security of operation; If the operation pipeline section has emptying, release flow process just, the utility model can be screwed on the plug 6 of air guide steel pipe handle 2 to get final product, not only convenient but also safety, and this is that " butter wall " is not available.

The accompanying drawing explanation

When considered in conjunction with the accompanying drawings, by the detailed description with reference to following, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, as schemed wherein:

Fig. 1 is structural representation of the present utility model.

Fig. 2 is structural representation of the present utility model.

Fig. 3 is structural representation of the present utility model.

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment

Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.

Embodiment 1: as shown in Figure 1, Figure 2 and Figure 3,

A kind of oil gas pipeline section isolating tool, air guide steel pipe handle 2 is vertically welded in circular discus 1 circle centre position; Air guide steel pipe handle 2 the other ends connect soft air-guide pipe 3;

The circle centre position of circular discus 1 is porose, and aperture is less than the external diameter of air guide steel pipe handle 2; The wet large cloth 4 of uniform winding on circular discus 1 circumference, and on the wet large cloth twined coating butter 5;

Air guide steel pipe handle 2 the other ends have outside thread to connect internal thread plug 6;

The length of soft air-guide pipe 3 is between 5m～6m.

Embodiment 2: as shown in Figure 1, Figure 2 and Figure 3,

A kind of oil gas pipeline section isolating tool, this kind of oil gas pipeline section isolating tool is comprised of circular discus 1, air guide steel pipe handle 2 and soft air-guide pipe 3, one end of air guide steel pipe handle 2 is vertically welded in the center of circular discus, the other end band outside thread is connected with soft air-guide pipe 3, and mates a supporting internal thread plug 6 with it.Circular discus 1 selects the iron plate of thickness between 4mm～5mm to make, and in the circle centre position perforate, aperture is slightly less than the external diameter of air guide steel pipe handle 2, guarantees the pipeline communication of aperture and air guide steel pipe handle 2, and the diameter of circular discus should be slightly less than on-the-spot internal diameter of the pipeline; Air guide steel pipe handle 2 material selections are counted Mi Changdu according to the site operation pipeline section degree of depth and fixed seamless steel pipe, to facilitate welding; The size of soft air-guide pipe 3 can well be tightly connected with the male end that air guide steel pipe handle 2 removes after plug 6, and length is between 5m～6m.At every turn should be first before using this instrument on circular discus 1 circumference the wet large cloth of uniform winding 4 a few, then spread a little butter 5, to guarantee the isolation effect of oil gas pipeline section.

As mentioned above, embodiment of the present utility model is explained, but, as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation also all is included in protection domain of the present utility model.
