(Practice)Standard Practice for Application of Thermal Spray Aluminum (TSA) Coating to Carbon Steel Pipe
Standard Practice for Application of Thermal Spray Aluminum (TSA) Coating to Carbon Steel Pipe
SIGNIFICANCE AND USE
5.1 The quality and effectiveness of TSA coatings is dependent on a variety of factors including surface preparation, coating materials, environmental conditions and control of the applications process. This practice addresses the fundamental variables and concerns relative to proper TSA application.
5.2 TSA has been proven to offer resistance to the atmospheric corrosion of carbon steel pipe and to corrosion under insulation (CUI). The publication NACE No. 12/AWS C2.23M/SSPC-CS 23.00, AWS C2.18 and NACE SP0198 provide additional information regarding the performance of TSA coatings.
SCOPE
1.1 This practice defines the minimum requirements for the application of Thermal Spray Aluminum (TSA) coatings to carbon steel pipe for the purpose of preventing atmospheric corrosion or corrosion under insulation. This practice is intended to be effective for TSA coatings applied at pipe manufacturing facilities or at on-site assembly locations.
1.2 This practice is for the application of TSA to the external surfaces of piping to prevent atmospheric corrosion of insulated and non-insulated surfaces.
Note 1: TSA has been found useful for temperatures up to 1000°F (540°C) for uninsulated surfaces and for preventing corrosion under insulation for pipes operating in the range of 25°F to 300°F (–4°C to 150°C) surface temperature.
1.3 This practice includes requirements for surface preparation, materials, application and quality control of TSA applied to carbon steel piping at the pipe manufacturing facility or at an on-site-assembly location.
1.4 This practice is expressed in both inch-pound and SI units. However, unless the order specifies the use of metric values, inch-pound units shall be used.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
