NEW NACE Standard Test Method for 2018! This NACE International test method describes a reliable methodology for determining the peel strength of polyolefin-based multilayer pipeline coating systems, generally for coating thickness less than 12 mm (0.47 in). This standard provides a method to measure the peel strength of polyolefin-based multilayer coating systems, such as 2-layer polyethylene coating [2LPE], 3-layer polyethylene [3LPE], 3-layer polypropylene [3LPP], and heat shrink sleeve[HSS] field joint coating. It provides essential information on the quality of the applied coating. This is particularly important for field-applied coatings, of which the application process is significantly impacted by the environmental conditions and the skill set of the field applicators. This test method is intended for use by pipeline operating companies, pipeline owners, pipeline contractors, pipeline inspection services companies, and pipeline coating mills.
New NACE TEST METHOD! The purpose of this NACE International standard test method is to specify test methods and test conditions used to evaluate thermal properties, insulation values, and performance/integrity before and after thermal aging of insulative coatings. Testing for corrosion resistance is not included in this test method.
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 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.
Revised in 2020! Assessment of corrosion in the field is complex because of the variety of applications, process conditions, and fluid phases that exist in industrial plants where corrosion occurs. A wide range of direct and indirect measurement techniques is available, but each technique has its strengths and weaknesses. In some applications, certain techniques cannot be used. Some techniques can be used online, while others are used off-line. Commonly, more than one technique is used so the weaknesses of one are compensated for by the strengths of another. In other cases, a combination of different techniques can be synergistic, such as process sampling along with detection of corrosion upset.
The purpose of this technical committee report is to analyze the various techniques with respect to their benefits and limitations across the broad spectrum of industries in which they are used.
This revision incorporates Guided Wave Monitoring (GWM), On-Line Gas Chromatography (GC), and Acoustic Solid Detection (ASD) techniques and updates references to NACE standards.
This technical report applies to water-using cooling and heating systems in buildings. It provides information for minimizing system damage and operational interference because of corrosion, scale, fouling, and microbiological growth in building heating, ventilation, and air conditioning (HVAC) systems. This includes open and closed circulating water systems, low-pressure steam boilers and hot water “boilers.” The document also addresses thermal energy storage systems, but does not address potable water or fire protection systems. It is intended for use by building owners and engineering, maintenance, and operations management personnel. It is also intended for use by those involved in the design and construction of building HVAC systems so that corrosion, scale, fouling, and microbiological growth problems described above can be understood, anticipated, and minimized through appropriate design decisions.
