This NACE International standard practice provides current technology and industry practices for the use of field-applied heat-shrinkable-sleeve coating systems. The standard is intended for use by corrosion control personnel, design engineers, project managers, purchasers, and construction engineers and managers. It is applicable to underground steel pipelines in the oil and gas gathering, distribution, and transmission industries.
The standard practice presents guidelines for establishing minimum requirements to ensure proper application and performance of field-applied, heat-shrinkable sleeves to the external surfaces of coated pipe. Included are methods for (1) qualifying and controlling the quality of a heat-shrinkable sleeve, (2) guidelines for proper application, and (3) inspection and repair techniques to ensure its long-term performance. The standard is applicable to coating systems used to prevent corrosion in conjunction with cathodic protection, and heat-shrinkable wraparound- or tubular-type sleeve coating systems on underground steel pipelines.
New in 2020! This standard presents accepted methods and practices regarding the use of cathodic protection (CP) for the control of external corrosion on buried or submerged carbon steel, stainless steel, gray cast iron, ductile cast iron, copper, and aluminum piping systems at nuclear power plants. This standard may be useful at facilities other than nuclear power plants that contain complex networks of buried or submerged piping, which may be composed of more than one material and may or may not be grounded.
