HISTORICAL DOCUMENT. This NACE Standard establishes material requirements for resistance to sulfide stress cracking (SSC) in sour refinery process environments, i.e., environments that contain wet hydrogen sulfide (H2S). It is intended to be used by refineries, equipment manufacturers, engineering contractors, and construction contractors.
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.
