Evaluation of the performance of offshore atmospheric and splash zone coating systems on platforms. Fixed-leg, semi-submersible, tension-leg, and floating production storage and offloading (FPSOs).
Pruebas para medir potenciales para determinar si un criterio de protección catódica (SP) se logra en un sitio de prueba en tuberías de acero, fiero, cobre o aluminio, subterráneas o sumergidas.
HISTORICAL DOCUMENT. This standard test method provides descriptions of the measurement techniques and cautionary measures most commonly used on underground and submerged piping other than offshore piping to determine whether a specific criterion has been met at a test site. This standard contains instrumentation and general measurement guidelines. It includes methods for voltage drop considerations when structure-to-electrolyte potential measurements are made and provides guidance to minimize incorrect data from being collected and used. This standard is maintained by Task Group 020.
HISTORICAL DOCUMENT. Two methods of evaluating relative carburization resistance of alloys used in ethylene cracking furnace tubes. Standardized data that allows evaluation of tube supplier carburization data.
HISTORICAL DOCUMENT 2008. Forming a successful Underground Corrosion-Control Coordinating Committee. Organizing meeting minutes and personnel directories. Samples of eight documents, including bylaws and reporting forms. Free.
This technical report presents state-of-the-art information on several commercially available galvanic cathodic protection/prevention systems for protecting atmospherically exposed reinforced concrete structures. The information contained in this report has been provided by key manufacturers of these systems and is intended as a technical resource for engineers responsible for the rehabilitation of reinforced concrete structures. It may also be useful to owners, contractors, and other practitioners related to the field of galvanic cathodic protection (CP). All information related to galvanic CP is intended for atmospherically exposed concrete structures and may not be applicable to concrete containing epoxy-coated reinforcing steel, galvanized, or other coated or nonferrous reinforcement.
The purpose of this NACE International technical report is to provide basic information regarding the mechanisms involved with cathodic protection (CP) shielding for external coatings applied to carbon steel pipelines, and the manner in which the breakdown of coating systems may or may not contribute to CP shielding. It is intended to be a basic reference from which the tendency of a coating system to fail and shield CP may be understood on a conceptual basis. Non-corrosion-related pipeline protection systems, including concrete weight coating, polyethylene encasement, insulation, and mechanical pipeline protection systems, are outside the scope of this report. End users of this report may include pipeline designers, corrosion engineers, integrity management specialists, regulators, CP service providers, coating suppliers, coating service providers, equipment suppliers, and pipeline/facility owners.
This technical report presents evaluation techniques which can potentially be used to complement performance criteria of international standards, especially if the criteria cannot be employed to evaluate the effectiveness of cathodic protection and corrosion control techniques applied to existing reinforced concrete structures, including atmospherically exposed, buried, and submerged structures.
This report:
This report is intended to be useful to architects, structural engineers, architectural conservators, and consulting engineers/contractors who are engaged in refurbishing steel-reinforced concrete structures and buildings.
