Description
Technical field
The utility model relates to a kind of detection facility, is a kind of easy to carry and use specifically, and directly can carry out to buried thermal pipeline the Portable thermal hydraulic piping detection device detecting flaw detection on ground.
Background technique
On the earth of our life, be that boundary extends to north and south with equator, dimension more high-temperature is lower.For China, to the north of the Yellow River, the lowest temperature in most area winter is all below-10 degrees Celsius, and the minimum temperature of In Winter of Heilongjiang Province is at-30 degrees centigrade.In order to enable the mankind at the activity zone of these colds, the north arranges heating equipment in the regional big city of population concentration, and these heating equipments all need the heat distribution pipeline by being laid on below ground to carry out heat conduction.
Enter winter, when heating equipment brings into operation, the state that high-temp liquid or steam flow through will be remained in heat distribution pipeline, heat distribution pipeline will be subject to high temperature corrosion, through the use of many decades, this high temperature corrosion often causes the localized seepage of heat distribution pipeline, and heating installation can not normally be run, and place of localized seepage also can pollute the environment moulding of surrounding.Therefore, need to adopt a kind of equipment or method, can detect accurately in advance, judge the position of heat distribution pipeline localized seepage, then by manually carrying out excavating and keeping in repair, the requirement of heat distribution pipeline and heating equipment long-time maintenance and normal use could be met.
