Abstract
The invention discloses a pipeline cleaning device, comprising a straight leather cup 1, a straight leather cup 2, two dish leather cups 3 and a shaft bracket, wherein, the diameter of the straight leather cup 1 is less than the diameter of the straight leather cup 2, meanwhile, peripheral edge of the straight leather cup 2 are provided with chamfers with a certain angle, the outer periphery of the straight leather cup is symmetrically provided with at least two small holes 4, the run-through capacity of the cleaning device in the pipeline is added, and the blocking phenomenon caused in the pipeline cleaning process is avoided.
Description
Technical field
The present invention relates to be used in a kind of industrial gas oil the wiper of pipeline pigging.
Technical background
Regulation and the standard relevant according to country, need oil and gas pipeline is carried out pigging and testing, by pipeline is detected, in time obtain the first-hand scientific information of pipeline good working condition at the pipeline initial stage of building up, in time find pipeline make, anticorrosion, laying stage is because defect of pipeline such as the construction operation mechanical damage that causes lack of standardization, weld seam abnormity point carry out necessary reparation and strick precaution; Can be with this as acceptance criteria to pipeline quality, the more important thing is in order to compare with the periodicity testing result of carrying out later on, judge that defect of pipeline is the tubing defective that can not grow or because anticorrosive coat destroys the developing fault that causes, thereby judge the speed of growth of corrosion, carry out the assessment of pipeline residual life.
At the pipeline pigging with detect in the work progress, carrying out the pigging work that deformation detection and corrosion must advanced line pipe roads before detecting, the purpose of pigging work is:
(1) removes pipe interior residue (long-pending oil, dust, construction legacy), to reduce its influence to testing result.
(2) checking pipeline machinery trafficability characteristic can be to guarantee passing through smoothly of checkout equipment.
(3) according to wiper and go out the principle condition clearly and confirm tentatively whether pipeline possesses the condition of the detector that puts into operation.
The equipment that must use in the pipeline pigging work progress is exactly wiper, detection company wiper commonly used has the leather cup wiper at present, the gauging disc wiper, bristle pig, two straight two dish wipers wherein are a kind of leather cup wipers of using always, it is by two straight leather cups 1,2 and two dish leather cups 3 and pedestal constitute, the external diameter of two straight leather cups all is the same with thickness, existing two straight two dish wipers bigger undergauge or pipeline distortion occur and pile up in wiper the place ahead under the situation of a large amount of foreign material the stifled phenomenon of card takes place easily if run into pipeline in the process of carrying out the pipeline pigging.
Summary of the invention
Now the technical problem that need solve is that wiper still can move on when bigger undergauge or bigger distortion appear in pipeline, does not block stifled phenomenon.
For solving the problems of the technologies described above, existing wiper is transformed, analyze the operation principle of two straight two dish wipers first.The main effect of two straight leather cups is foreign material of releasing in the pipeline, it and pipeline blow-by, two dish leather cup external diameters are bigger than the internal diameter of pipeline, seal with the pipeline internal diameter, can make the front and back of wiper form certain pressure reduction, promote wiper operation forward in pipeline.
Consider that there is the situation of undergauge or distortion in pipeline, two straight leather cups of two straight two dish wipers are selected different external diameters for use, the diameter of second straight leather cup 2 is an internal diameter of the pipeline, the diameter of the first straight leather cup 1 is slightly less than the diameter of the second straight leather cup 2, while, second straight leather cup 2 got the chamfering of certain angle along the edge, and have at least two apertures 4 in straight leather cup excircle symmetry, the ability of releasing foreign material in the wiper in-line running is reduced, wiper the place ahead is unlikely to pile up a large amount of foreign material, what strengthen wiper can cross ability, does not block stifled phenomenon.
Description of drawings:
Fig. 1 is the structural representation of two straight two dish wipers
Fig. 2 is the schematic diagram of the straight leather cup of wiper of the present invention
The specific embodiment:
Be the design of carrying out two used straight two dish wipers of pigging for the pipeline of DN600 below, the pipeline internal diameter of the pipeline of DN600 is 588mm, so the external diameter of second straight leather cup is selected 588mm for use, and the outer grade of first straight leather cup is selected 580mm for use, so just can guarantee first straight leather cup easier passing through when undergauge appears in pipeline, the angle that chamfering is got at second straight leather cup 2 edge is 15 degree, each is separated by 90 ° and opens four apertures 4 on straight leather cup, and diameter is that 30mm. reduces the ability of releasing foreign material in the wiper in-line running, wiper the place ahead is unlikely to pile up a large amount of foreign material, the wiper maximum can be by the deflection of pipeline 30% like this, what strengthened wiper can cross ability, reduce the stifled risk of card takes place, guaranteed normally carrying out of pipeline pigging work.
Claims (3)
1. pipeline cleaner, comprise two straight leather cups 1,2 and two dish leather cups 3 and pedestals, it is characterized in that: the diameter of the first straight leather cup 1 is slightly less than the diameter of the second straight leather cup 2, while, the chamfering of certain angle was got in second straight leather cup 2 edge, and had at least two apertures 4 in straight leather cup excircle symmetry.
