This standard specifies requirements and gives recommendations for the pre-installation surveys, design, materials, equipment, fabrication, installation, commissioning, operation, inspection and maintenance of cathodic protection (CP) systems for offshore pipelines for the petroleum, petrochemical and natural gas industries as defined in ISO 13623. It is applicable to carbon steel, stainless steel and flexible pipelines in offshore service, and to retrofits, modifications and repairs made to existing pipeline systems. Key words: Cathodic protection, impressed current, offshore pipeline, CP system design, galvanic anode, galvanic anode manufacturing, galvanic anode quality control, pipeline design for CP This nationally adopted ISO standard is not available for complimentary download by members.
This NACE Standard Practice aims to provide guidance for selection and application of Corrosion Inhibitors (CI) for upstream oil and gas processes conditions exposed to corrosive environments.
The application of effective Corrosion Inhibitors (CI) in Oil and Gas production is essential to enable long term use of carbon steel in corrosive production environments. These chemical CI products can be applied continuously, or on a Batch (BI) basis. The effectiveness of CIs(products) that are applied has to be assured for the range of conditions associated with the application and for the lifetime of the facility. The assurance is predominantly achieved through laboratory testing. However, field evaluation of CIs can be a significant part of the assurance process.
Erosion is defined by NACE International as “The progressive loss of material from a solid surface resulting from mechanical interaction between that surface and a fluid, a multicomponent fluid, or solid particles carried with the fluid.”
This SP provides guidance on internal erosion and erosion-corrosion management. Guidance is given for erosion and erosion-corrosion threat assessment/prediction, barrier selection, monitoring, inspection, risk assessment and data management. This SP covers mainly sand caused erosion. However, the guidance in this document can be used for other solid particles.
This SP is applicable to tubular products, e.g., tubing, pipelines, flowlines, risers, valves, and piping systems.
