2018-11-15

Special survey, reporters from the province was informed that capacity at the Hospital Center recently entrusted with the inspection of city buried gas steel pipeline, used 5 innovative techniques, testing technology has made new breakthroughs.

Urban buried steel gas pipeline inspection are difficult test items in the special equipment inspection. The by used of 5 items innovation technology respectively is: used exploration to radar for precise positioning, measurement pipeline buried deep and spacing; using more frequency tube in the current detection technology, detection pipeline anti-corrosion layer damaged points and evaluation anti-corrosion layer quality grade; using key interval potential test technology, analysis judge protection system of effectiveness; using dynamic miscellaneous bulk current detection system, measurement pipeline around of miscellaneous bulk current interference degree; using fuzzy integrated evaluation method, determine pipeline of risk grade.
