STUDY OF A DELAMINATION FAILURE IN A THREE LAYER COATING OF A 24' GAS PIPELINE IN VERACRUZ, SOUTH EAST MEXICO.

摘要

The three layer pipeline coating system is one of the fastest growing and more accepted systems in the world, in great part due to the combination of the excellent adhesion properties of the FBE,and the excellent water impermeability and mechanical resistance of the HDPE. We report a case study of a disbondment failure occurred at a 24" gas pipeline and the steps taken to try to determine the root cause of the failure.
