New Breakthrough In The Urban Buried Gas Pipeline Inspection Technology
Nov 29, 2016

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.
