Abstract
The invention relates to a rapid repair device for the leakage of a pipeline flange connection. The rapid repair device comprises a box; a flange with a plurality of bolts arranged at equal intervals is arranged in the box; the box is filled with a composite refractory material which is capable of penetrating into the leakage position of the flange connection. The rapid repair device for the leakage of the pipeline flange connection is capable of quickly handling the leakage point of the pipeline flange connection on the spot without shutting down the pipeline, and therefore, the normal production is not affected, the time and the labor are saved and the low is relatively low; the composite refractory material has excellent penetrability, cohesive force, acid resistance and corrosion resistance; the box and the refractory material can be detached quickly in future without damaging pipeline equipment; as a result, the rapid repair device can be popularized and utilized to the leakage of the facilities of various medium pipelines, such as inspection manholes and expansion joints.
Description
Technical field
The invention belongs to pipe-line equipment restorative procedure technical field, relate to one
piping flange interface reveals quick-restoring device and restorative procedure thereof.
Background technique
Flange is interconnective part between pipe and pipe, for the connection between pipe end.Piping flange means the flange of pipe arrangement in tube equipment, is used in import and export flange equipment meaning equipment.Flange joint refers to and is interconnected releasable connection as one group of combined sealing structure by flange, pad and bolt three.Perforation on flange, bolt makes two flanges be close to, and uses liner containment between flange.Shrink by pipeline, the factor such as the corrosion of pipeline internal medium affects, flange-interface may produce leakage.Flange-interface leaks the bolt hole mainly containing leakage, flange between flange plate and leaks two kinds of situations.Existing common repair methods is closing duct, readjusts or mounting flange.Some vital process pipes, may need the continuous service keeping twenty four hours, if closing duct, part run then must stop production, and cost is larger.Meanwhile, closing duct needs the regular hour, and has certain danger.Therefore, common repair methods not only affects the normal use of pipeline, increases cost of production, and inconvenient operation, consuming time longer.
Summary of the invention
For overcoming above-mentioned technical disadvantages, the invention provides a kind of when without the need to closing duct, completing flange-interface fast and revealing reparation, reduction labor intensity
piping flange interface reveals quick-restoring device and restorative procedure thereof.
The present invention solves the technological method that its technical problem adopts: a kind of
piping flange interface reveals quick-restoring device, comprises a casing, is provided with one with the flange of the bolt of several equidistant arrangement, is filled with in casing in casingcomposite refractory, this composite refractory and then infiltrate into flange-interface leakage place.
above-mentioned piping flange interface reveals the restorative procedure of quick-restoring device, and its reparation step is:
The first step: according to flange size and pipeline pressure size, makes a sizeable casing with steel plate, is wrapped by flange-interface;
Second step: preparation composite refractory, choose component and weight proportion is: clay chamotte 50 ~ 57, clay brick particle 30 ~ 35, alumina cement 3 ~ 5,85% phosphoric acid 5, water 3 ~ 5, size according to pipeline pressure chooses suitable material according to above weight proportion, then above-mentioned material is put into stirrer and stirs the composite refractory making suitable consistency;
3rd step: the composite refractory prepared is poured in the casing of the first step, make composite refractory can infiltrate into flange-interface leakage place, till composite refractory fills whole casing, depending on pipeline working temperature, just can bond in composite refractory a few minutes, elimination flange-interface is revealed, solid in about one to two hour, strengthens repairing effect further.
The invention has the beneficial effects as follows: can when without the need to closing duct, administer piping flange interface leak point fast at the scene, do not affect normal production, save time, laborsaving, cost is lower; Composite refractory possesses excellent degree of oozing power, cohesive force, acid resistance, corrosion-resistant, can not damage pipe-line equipment by fast dismantling from now on except casing and refractory material, and the facility such as inspection manhole, expansion joint can promoted the use of to various medium pipeline is revealed.
Accompanying drawing explanation
Fig. 1 is embodiments of the invention schematic diagram;
Fig. 2 is the side view of the embodiment of the present invention.
In figure: 1-flange, 2-casing, 3-composite refractory, 4-bolt, 5-flange-interface.
embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
See Fig. 1 and Fig. 2, a kind of
piping flange interface reveals quick-restoring device, comprises a casing 2, is provided with one with the flange 1 of the bolt 4 of several equidistant arrangement, is filled with in casing 2 in casing 2composite refractory 3, this composite refractory 3 and then infiltrate into flange-interface 5 leakage place.
above-mentioned piping flange interface reveals the restorative procedure of quick-restoring device, and its reparation step is:
The first step: according to flange 1 size and pipeline pressure size, makes a sizeable casing 2 with steel plate, is wrapped by flange-interface 5;
Second step: preparation composite refractory 3, choose component and weight proportion is: clay chamotte 50 ~ 57, clay brick particle 30 ~ 35, alumina cement 3 ~ 5,85% phosphoric acid 5, water 3 ~ 5, size according to pipeline pressure chooses suitable material according to above weight proportion, then above-mentioned material is put into stirrer and stirs the composite refractory 3 making suitable consistency;
3rd step: the composite refractory 3 prepared is poured in the casing 2 of the first step, make composite refractory 3 can infiltrate into flange-interface 5 leakage place, till composite refractory 3 fills whole casing 2, depending on pipeline working temperature, just can bond in composite refractory 3 a few minutes, eliminate flange-interface 5 to reveal, solid in about one to two hour, strengthen repairing effect further.
The invention has the beneficial effects as follows: can when without the need to closing duct, administer piping flange interface 5 leak point fast at the scene, do not affect normal production, save time, laborsaving, cost is lower; Composite refractory 3 possesses excellent degree of oozing power, cohesive force, acid resistance, corrosion-resistant, can not damage pipe-line equipment by fast dismantling from now on except casing 2 and refractory material, and the facility such as inspection manhole, expansion joint can promoted the use of to various medium pipeline is revealed.
