Gas, the condition of water quality complexity of long celebrating gas field rock gas, gasser, gas gathering station are in the field on the geographical plane, the some polydispersion, caliber is changeable, and tubing is various, the individual well flow line, defeated of collection, main line corrosion monitoring difficulty, electric-resistivity method and inductance method are being subjected to influence of temperature change in varying degrees.And the nearly 20000mg/L of above-mentioned gas field salinity content, chloride content is about 10000mg/L, and part wellblock CO2, H2S content are also higher relatively, and topographic relief is bigger, laminar flow and polyphasic flow can appear in the gas pipe line inner fluid, and the low-lying pipeline section of part is prone to bubble erosion and stagnant district.
The utility model content
The purpose of this utility model is: a kind of natural gas line on-line corrosion monitoring device is provided, under the condition of extraneous temperature variation, still can carries out on-line corrosion monitoring accurately to the natural gas line of unlike material, different pressures; The pipeline inner fluid is carried out laminar flow and polyphasic flow corrodes detection;
The technical solution adopted in the utility model is: natural gas line on-line corrosion monitoring device, form by production flow line, valve, bypass line and lacing film device, valve is arranged on production flow line, both sides at valve are welded with pipeline respectively, be fixed with valve on the pipeline respectively, be connected with bypass line between two valves; It is characterized in that: be welded with the lacing film device on the bypass line.Described lacing film device is mainly formed by detecting short tube, union (screwed)bonnet (UB, lacing film support, insulating mat, lacing film and hold-down nut; There is screw thread the upper end of detecting short tube, is fixed with union (screwed)bonnet (UB in the detection upper end of short tube by detecting the short tube screw thread, in the union (screwed)bonnet (UB lower end screw is arranged, and is fixed with the lacing film support in the bottom of union (screwed)bonnet (UB by screw.The lacing film support is the cylinder bodily form, and there is external thread the upper end; Hexahedron is arranged at the externally threaded bottom of lacing film support, can use fixedly lacing film support of spanner.Cylindrical bar is arranged at the bottom at hexahedron, and external thread is arranged at the bottom of cylindrical bar.On the cylindrical bar of lacing film support, be with the annular lacing film, between adjacent two annular lacing films, insulating mat arranged.There is hold-down nut cylindrical bar lower end at the lacing film support.
The quantity of described annular lacing film is between 3～12.
The material that described insulating mat adopts is acrylic fibers.
Natural gas line on-line corrosion monitoring device workflow: consult Fig. 2.At first insulating mat 4 is enclosed within on the lacing film support 3; Select to be enclosed within on the lacing film support 3, between adjacent two lacing films 5, an insulating mat 4 is arranged with a plurality of lacing films 5 of the identical material of pipeline; Hold-down nut 6 is fixed on the lower end of lacing film support 3.Utilize spanner that the upper end of lacing film support 3 is fixed on the union (screwed)bonnet (UB 2.At last the lacing film string is inserted and detect in the short tube 1, tighten and detect short tube 1, make its sealing.
Close production flow line merchant's valve, open the valve 8 on the bypass line.On-line corrosion monitoring begins.Get when throwing lacing film, make bypass line not have oil (stream by switching valve 8.Take out lacing film.
The beneficial effects of the utility model: the utility model natural gas line on-line corrosion monitoring device, can be under multiple pressure, temperature conditions, online corrosion detects to natural gas line, and the result is accurate, for the pipeline pigging provides data; Do not influence under the situation of production and remove lacing film, can reuse, reduce and detect construction volume, reduction of expenditure can be in the widespread use of oil gas field production field.
