1. Scope
This new Standard Guide will enable the user to logically address a number of technical aspects of buried pipe coating selection, including: The function of buried pipe coatings in nuclear power plants, The plant systems which may include coated buried pipe, The generic types of field-applied buried pipe repair and refurbishment coatings, Technical factors which affect the selection of field-applied buried pipe repair and refurbishment coatings, In situ (in-ditch) factors which affect the selection of field-applied buried pipe repair and replacement coatings, and, ASTM and other standards used to evaluate the performance of field-applied buried pipe repair and refurbishment coatings. This standard provides guidance for the selection of coating materials to be used to repair of external coatings on buried pipe in power generating facilities and includes piping under the following conditions: Low temperature (200 F) Low pressure (excludes TBD) Excludes piping under federal regulations (PHMSA) Coating materials included within the scope of this standard include: Liquid applied Tape wraps Shrink sleeves Melt sticks Paste Wax Non-structural fiber composite wraps Thermal spray
Currently there is not a consensus guide for selection of coatings for repair and rehabilitation of buried pipe coatings in nuclear power plants. Adoption by NRC, EPRI
