... ABSTRACT Blisters are one of the most frequently observed failure modes in FBE coatings of buried pipelines. Initial small disbondment defects at the coating-steel interface, due to embedded abrasives and voids are potential sites for blisters to form and grow. Two types of blisters...

... ABSTRACT Pipelines installed using horizontal direct drilling (HDD) are normally buried deep with complex strata. Due to its limited accessibility, there is no other effective methods other than in-line inspection (ILI) to evaluate pipe coating defects and other corrosion damages. ILI...

... and cathodic protection to all buried pipelines. Inside the casings, the gas pipeline is coated but not buried and of course, it is surrounded by air. Therefore the cathodic protection cannot act. In order to develop external corrosion processes on the pipes inside the casings, a coating defect may be produced...
