Need: Performance characteristics of select coating systems when subjected to horizontal directional drilling (HDD) and slip boring installation loads was needed to be used in the design of optimal coating systems when using these methods of pipeline installation.
Result: Research began with a literature search to obtain relevant background material. Existing test methods were examined to determine their applicability to HDD and slip boring loads. Two generally applicable methods were identified, Technical Inspection Services (TISI) Gouge Test and the Taber Abraser Test (ASTM D 4060). To reinforce the results of the laboratory testing, a procedure was developed to verify the performance of the selected coating systems on actual HDD installations. Thios involved documentation of the general parameters of the installation, such as length, diameter, and surface conditions and then measuring the quality of the coating system after installation using the procedure developed under PRCI contract number PR-262-9738 titled "In-Situ Evaluation of Directional Drill/Bore Coating Quality, Evaluation of Test Methods". Ten (10) coating systems were selected for examination and an eleventh was added at a manufacturer's request and cost including; 3M 6352, Thanecoat TC-700, Powercrete, Lilly 2040, 3M 206N, SPC 2888, Powercrete J, Isotube, Zebron, NapRick, CeramGard ML.
Benefits: The results of this comprehensive study provide guidance and recommended practices for the installation of pipelines utilizing the HDD and/or slip boring techniques to minimize defects on pipe coating systems and to assist pipeline operators in the selection of the proper coating systems for the soil and rock characteristics expected. Significant cost savings and enhanced pipeline integrity result from use of the proposed recommended practices.
