For pipe installed through bore methods, visual inspections and electronic coating holiday detectors during installation becomes impractical. This paper/presentation will discuss the steps we took as a pipeline operator to find a practical approach to performing a coating quality test on bored pipe.

Two drilling mud samples, taken at different HDD operations. Results demonstrated the presence of microorganism populations associated with microbiologically influenced corrosion (MIC) at one of the two test locations.
Laboratory and field experiment results show that the soil resistivity is the main influencing factor of the cathodic protection current distribution of horizontal directional drilling. This article also gives a test method for effectiveness of cathodic protection of HDD.
The purpose of the “Bore Test” is to know the external quality of the coating after the installation of the pipe section, as picture 1. NACE standard “TM-102-2002-SG”1a defines four kinds of coating quality such as: excellent, good, fair and poor. To know the final quality of coating with this procedure. It was used two different electrical tests. DC current test using minimum voltage drop method and, the 3 pole test which is called by the same manufacture of the Multifunction Ground Resistance tester.
This paper will identify the potential causes of pipe coating failure, from the design angles to the soil types, to the fracture methods of rocks, and pull forces. It will present a logical method for evaluating the condition of an HDD pull prior to its installation so that the right level of coating protection may be applied. The pipelines that carry our world's energy and industrial networks are a vital lifeblood of our society. HDD’s play such an integral part in keeping all aspects of the pipeline and its construction running smoothly, the aim here it to ensure there are no hiccups along the way.
