The pipeline always has to be in good repair. Otherwise blockages in pipe can lead to emergence of the emergencies connected with its break. Therefore it is regularly so important to check passability of pipes that will allow to reveal not only availability of blockages, but also level of wear of system.
Instruction
1. Check of passability of the pipeline in the apartment is most often carried out by means of teleinspection diagnostics. The small video camera having high resolution and accurate illumination acts as its basic element. Movement of the camera on the pipeline is made by means of the pushing cable. The image from the video camera is transferred to the monitor.
2. Diagnostics of the filled system is carried out by means of the floating module. For this purpose the equipment by means of special design is started on liquid Wednesday where it is fixed horizontally. The finished shooting video is transferred to the digital carrier for further viewing and the analysis of condition of pipe. Advantage of such way of check of passability of the pipeline consists in possibility of carrying out work even in the most hard-to-reach spots without the need for dismantling of objects that has become possible due to compactness and mobility of the used equipment.
3. In certain cases for the analysis of passability of pipes the diagnostic system with replaceable nozzles is used. Centering of head of the camera placed in system in this case can be made by either the ball, or lobe guides executed in the form of star with set of beams.
4. It is possible to find the blockages promoting deterioration in passability of the pipeline also by means of acoustic way. Heat carrier speed sharply increases in places where there is narrowing of the section through passage of pipe, therefore in the place of blockage there is increase in noise which can be heard without use of the special equipment.
5. The quality of the pipeline having big extent can be checked by means of the ultrasonic equipment. This way means use of laid on ultrasonic sensors that allows to check passability of pipe without violation of its integrity and interruption of technological process. For this purpose sensors by means of quick disconnect collars are installed on pipes then setup of the flowmeter taking into account quality of the received signal in any given place is made. The system itself prompts on what distance from each other there have to be sensors. All this allows to obtain the most reliable data.
