摘要
Abstract
Before road construction,anti-rolling protection measures should be taken for the crossing pipeline section,and the gas transmission pipeline crossing the road can be protected by box culverts.The integrity inspection of the crossing pipeline section mainly includes the verification of pipeline wall thick-ness,inspection of pipeline welds and detection and re-pair of anti-corrosion coatings.The circumferential weld inspection mainly includes appearance inspec-tion,upstream and downstream pipeline inspection of the weld,non-destructive testing of the weld and defect repair.The detection and repair of anti-corrosion coat-ings mainly include anti-corrosion coating detection and joint repair,and anti-corrosion coating repair.When the communication optical cable laid along the gas transmission pipeline is far away from the pipeline,the position of the communication optical cable should be adjusted to be inside the box culvert,and a backup op-tical cable should be set up.关键词
