Abstract
The utility model discloses a pipeline protector under mud-rock flow effect, the device include that pipeline, pipeline protect casing, support ring constitute outward. The protective sleeve sets up in the outside of pipeline, separates by the supporting pad between, and the total length of protective sleeve is equivalent with the protection pipeline protection length of needs, connects through welded form between every protective sleeve, links together through the toper casing between protective sleeve tip and the pipeline tip. The support ring can be made of polytetrafluoroethylene, rubber and engineering plastics. The utility model provides a protector can prevent effectively to block or slow down the direct impact effect of mud-rock flow to the pipeline, reduces situations such as pipeline local rupture, pit, deformation, promotes the shock resistance of pipeline, and the shared space of this protector is little, simple structure, and it is convenient that the construction is laid, is applicable to the pipeline that is in different topography ring border.
Description
Technical Field
The utility model relates to a protector, in particular to protector suitable for pipeline is under mud-rock flow impact
Background
With the vigorous development and construction of long-distance pipelines in China, the pipelines inevitably pass through sections which are easy to cause natural disasters. Once the pipeline is damaged under the impact action of debris flow disasters, huge economic losses can be brought, and the life and property safety of surrounding residents can be seriously threatened. Therefore, it is very necessary to add protective measures to the oil and gas pipelines which are already built or are being built in China and enhance the capability of the oil and gas pipelines to resist debris flow disasters.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a protector can realize effectual protection to the oil gas pipeline with simpler structure.
The utility model adopts the technical proposal that: a device for protecting a pipeline under the impact action of debris flow mainly comprises the pipeline, a pipeline outer protecting sleeve, a supporting ring and the like. The protective sleeve sets up in the outside of pipeline, separates by the supporting pad between, and the total length of protective sleeve is equivalent with the protection pipeline protection length of needs, connects through welded form between every protective sleeve, links together through the toper casing between protective sleeve tip and the pipeline tip.
The support ring can be made of polytetrafluoroethylene, rubber, engineering plastics and the like.
The material of the protective sleeve can be the same as that of the pipeline.
The pipe wall thickness of the outer protective casing of the pipeline is 8 mm.
The thickness of the support ring is set to be 0.1m, and the length of the support ring is 1 m.
The spacing of each ring is 4 m.
According to the utility model discloses the scheme, its beneficial effect lies in:
the sleeve type protection structure has certain strength, can effectively block or slow down the direct impact effect of debris flow on the pipeline, reduces the situations of local fracture, pits, deformation and the like of the pipeline, and improves the impact resistance of the pipeline.
The pipeline and the external protective sleeve are spaced by the supporting ring with certain flexibility, so that the impact force transmitted to the pipeline can be buffered, and the direct impact on the pipeline is reduced.
The protection device has the advantages of small occupied space, simple structure and convenient and fast construction and laying, and is suitable for pipelines in different terrain environments.
Drawings
Fig. 1 is a schematic perspective view of a pipeline protection device under the action of a debris flow.
Fig. 2 is a schematic cross-sectional view of the present invention.
In the figure: 1. support ring, 2, pipeline, 3, protection casing, 4, tip casing.
Detailed Description
Embodiments of the present invention are described below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art.
As shown in fig. 1 and 2, the utility model comprises a pipe 2, which is separated from a protective sleeve 3 by a support ring 1, and the end of the protective sleeve 3 is connected with the pipe 2 by a cone-shaped shell.
The utility model discloses a working method is: once there is the mud-rock flow or when the deposit acts on the pipeline, firstly carry out direct impact action to the external protection pipeline, and then pass on the pipeline with the impact force through the support ring to alleviate the direct impact action to the pipeline.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive. Various modifications and additions may be made thereto by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
Claims (2)
1. The utility model provides a pipeline protector under mud-rock flow effect which characterized in that, protector comprises pipeline, the outer protective casing of pipeline, support ring, the outer protective casing of pipeline length and the pipeline length that needs to protect match, every outer protective casing of pipeline between connect through welded form, the outer protective casing of pipeline tip and pipeline tip link together through the toper casing.
