Abstract
The utility model discloses an inside liner leakage detector for a composite steel tube, which comprises a steel tube and a non-metallic layer lined on the inner wall of the steel tube, wherein, the tube wall of the steel tube is provided with a small hole which is provided with a pipeline liquid sensor which is connected with an indicating device. When an inside-liner non-metallic layer is damaged, the liquid in the pipeline enters between the non-metallic layer and a metallic layer, and the sensor detects the leaked liquid and transmits signals to the indicating device so as to remind the personnel to replace the pipeline in the section as soon as possible. The utility model provides probability for manufacturers to use composite pipelines.
Description
Affiliated field
The utility model relates to a kind of pipeline leakage testing device.
Background technology
In the ion film caustic soda process units; ion-exchange membrane electrolyzer for the protective price costliness; relatively stricter to material (catholyte) quality requirements that advances electrolytic tank; the concentration that requires ferric ion in the catholyte is less than 0.1ppm; therefore the catholyte circulation line must use the material of anti-caustic soda corrosion, to prevent causing the damage of the concentration over-standard of ferric ion in the catholyte to ion-exchange membrane electrolyzer because of the corrosion of material.Domestic each ion film caustic soda manufacturer is several below the general consideration when selecting catholyte circulation line material for use at present: 1, nonmetallic materials: polypropylene, chlorinated polyvinyl chloride pipe material; 2, compound substance: carbon steel pipe lining teflon; 3, simple metal material: pure nickel pipe.Pros and cons with these three kinds of materials are: the lower but pad of first kind of material price easily leaks, and often causing is forced to stop handles leakage point, and production status is very unstable; Second kind of material price is moderate, the multistage pipeline connects with flange, the junction good seal performance, the pipeline long service life, but just in case because of the fabricating quality problem inner liner of pipeline when damaged, cannot find is which depot siding goes wrong, and can not in time change and can cause catholyte iron content height, thereby can cause expensive ion-exchange membrane electrolyzer to damage, so each ion film caustic soda manufacturer is all careful selects for use; Second kind of material price costliness, the life-span is long, but invests hugely, and each producer selects for use less.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of inner liner leak detecting device that uses composite steel tube and easy detection to leak the composite steel tube of pipeline section, solves the defective that can't use composite steel tube in the prior art and influence production.
For achieving the above object, the technical solution of the utility model is: the inner liner leak detecting device of composite steel tube comprises steel pipe, be lining in the non-metallic layer of steel pipe inwall, the tube wall of described steel pipe is provided with aperture, the pipeline liquid sensor is installed in the aperture, and the pipeline liquid sensor is connected with indicating device.
Owing to adopt technique scheme, the inner liner leak detecting device of composite steel tube comprises steel pipe, is lining in the non-metallic layer of steel pipe inwall, and the tube wall of described steel pipe is provided with aperture, the pipeline liquid sensor is installed in the aperture, and the pipeline liquid sensor is connected with indicating device; When the liner non-metallic layer is damaged, liquid enters between non-metallic layer and the metal level in the pipeline, so sensor had both detected leakage liquid, and signal is passed to indicating device, in time remind the staff to change this depot siding as early as possible, provide possibility for manufacturer uses compound pipe.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
As shown in drawings, the inner liner leak detecting device of 1 composite steel tube comprises steel pipe 1, is lining in the non-metallic layer 2 of steel pipe inwall, and the tube wall of described steel pipe 1 is provided with aperture 3, pipeline liquid sensor 4 is installed in the aperture 3, and pipeline liquid sensor 4 is connected with indicating device 5.
When 2 breakages of liner non-metallic layer, liquid enters between non-metallic layer 2 and the metal level 1 in the pipeline, so sensor 4 had both detected leakage liquid, and signal is passed to indicating device 5.
