By the method for repairing the non-standard steel pipeline crack under the working state, quick repairing of the crack of the non-standard steel pipeline under the working state can be realized, repairing is convenient, quick, time-saving and labor-saving in site construction.
Description
Technical field
The present invention relates to repair the nonstandard steel pipeline method of breaking, relate in particular to a kind of lower method of repairing the pipeline that breaks in working order.
Background technique
Pipeline is widely used in plumbing, heat supply, air feed, long apart from the field such as oil and natural gas conveying, agricultural irrigation, hydraulic engineering and various commercial plant.But in the using process of pipeline, because aging, burn into are safeguarded the reasons such as improper, pipeline inevitably can break.Pipeline breaking not only affects the normal operation of production, also can cause the wasting of resources, and then brings huge economic loss, even also can threaten people's life safety.Therefore, need in time pipe crack to be repaired.
At present, the method for repairing and mending of metal burst pipe commonly used has: 1. close fluid delivery valve, stop whole or local conveying operation, with metal conveyance conduit and joint complete removal thereof, new pipeline is installed; 2. cut off the delivery pipe rent, and at the two ends tapping, adopt flange to connect; 3. after the interface alignment with thin-wall metal pipeline, adopt the mode of welding or adopt the method for indent to connect.But above-mentioned three kinds of methods exist all that the repairing time is long, efficient is low and need to stop carrying the shortcoming of operation etc.And the repairing time of burst pipe is longer, more can aggravate dysgenic degree.Therefore, in time find pipeline breaking, and rapidly pipe crack is repaired the particularly necessity that seems, the fast repairing method of seeking metal pipe slit just becomes an extremely urgent problem.
Patent CN201487472U has announced a kind of metal thin-wall pipe that breaks and has repaired fast joint, comprises knob, circular ring, conical seal ring, connecting tube, tapered collar.The connecting tube two ends are threaded connection respectively knob, are positioned over respectively the conical seal ring that first and second thin walled tube outer surface contacts in two knobs, place tapered collar on the conical surface of conical seal ring, and conical seal ring is placed circular ring on the other end.This reparation joint can under the prerequisite that does not stop operation, be realized the quick reparation to the thin-wall metal pipe that breaks or permeate.But this invention is restricted to the wall thickness of metal tube, and is applicable to the reparation to the standard pipe crack, the problem such as have when being used for non-standard pipeline that rehabilitation cost is too high, joint setup time is long.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of for pipe crack method for repairing and mending non-standard steel pipe, easy and simple to handle, with low cost, that can repair under the pipeline working state.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The method for repairing and mending in nonstandard steel pipeline crack under a kind of working state, carry out according to following steps:
The cleaning of A, pipe crack: iron rust, dust, the spot of pipe crack surrounding are cleaned out;
The welding of B, steel plate strip I: at first steel plate strip I is processed into the pipeline cylindrical semicircle accordingly, airtight both sides that are welded in pipe crack of make-up in twos respectively then;
C, steel plate strip II's is fixing: at first steel plate strip II is processed into and corresponding two semicircles of steel plate strip I cylindrical, the valve of one logical liquid is set on one of them steel plate strip II, at last two semicircle steel plate strip II make-ups is overlapped on the steel plate strip I of pipe crack both sides;
The welding of D, steel plate strip II: at first open valve, then under the state of valve opening, two steel plate strip II are carried out seal welding and fix, weld complete rear throttle down.
Further improvement of the present invention is: the width of described steel plate strip I is 2cm～3cm.
Further improvement of the present invention is: the material of described steel plate strip I and steel plate strip II is identical with the material of pipeline.
Further improvement of the present invention is: described valve is connected with water port on steel plate strip II by pipe collar.
Further improvement of the present invention is: described pipe collar is arranged at the intermediate portion of steel plate strip II.
Owing to having adopted technique scheme, the obtained technological progress of the present invention is:
Present invention can be implemented under nonstandard steel pipeline working state the Rapid-Repair to its crack, field patch easy construction, save trouble and labor.The present invention only adopts steel plate strip to carry out repairing work, can determine the length of steel plate strip according to the external diameter size of crack pipeline to be repaired in operation site, and material is prepared quick and easy, and with low cost.The present invention treats size and the wall thickness no requirement (NR) of repairing steel pipeline, and applicability is strong, simple to operate, easy row, and cost performance is high, and the pipe crack repair efficiency is good.Greatly avoided because the crack appears in pipeline, and repaired untimely and a series of safety problems and economic loss that produce had both guaranteed the normal operation of pipeline, improved again the working efficiency of repairing work.
The present invention arranges a valve in the intermediate portion of steel plate strip II, in order to derive the pipeline liquid that flows out from pipe crack, avoided affecting weld job and welding quality because the pipeline liquid overflow is surperficial to position to be welded, further improved the welding quality when pipe crack is repaired.
The present invention adopts pipe collar to realize link between steel plate strip II and valve making the easier for installation, quick of valve, has promoted to a certain extent the standard configuration that pipe crack is repaired raw materials, has further improved the repairing efficiency of non-standard pipe crack.
