This document describes general principles and gives requirements and recommendations for the selection and qualification of metallic materials for service in equipment used in oil and gas production and in natural-gas sweetening plants in H2S-containing environments, where the failure of such equipment can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements given in the appropriate design codes, standards, or regulations. This document addresses all mechanisms of cracking that can be caused by H2S, including sulfide stress cracking, stress corrosion cracking, hydrogen-induced cracking and stepwise cracking, stress-oriented hydrogen-induced cracking, soft zone cracking, and galvanically induced hydrogen stress cracking. Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions. This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see Clause 5. This document is not necessarily applicable to equipment used in refining or downstream processes and equipment.

 

This document gives requirements and recommendations for the selection and qualification of carbon and low-alloy steels for service in equipment used in oil and natural gas production and natural gas treatment plants in H2S-containing environments, whose failure can pose a risk to the health and safety of the public and personnel or to the environment.

This document specifies a test method for determining the compressive creep behaviour of boxes made of thermoplastic materials intended for use in a modular system for non-pressure underground conveyance and storage of surface water.

 

This document specifies a test method for determining the long-term compression strength for a specified period on boxes made of thermoplastics materials for non-pressure underground conveyance and storage of non-potable water. The document is applicable for boxes which maintain their linear behaviour over the specified period.

 

This document gives the definitions and specifies the minimum requirements for injection moulded, extruded and thermoformed thermoplastics cuboid shaped boxes, including integral components, used in underground systems for infiltration, attenuation and storage of surface water (e.g. storm water) and manufactured from polypropylene (PP) or unplasticized polyvinylchloride (PVC-U). Product properties are determined by a combination of material specifications, design and manufacturing process. These boxes are intended for buried underground use, e.g. in landscape, pedestrian or vehicular traffic areas. A box can either be factory assembled, or site assembled from different components. These boxes are intended to be used as elements in a modular system where the manufacturer states in the documentation how the components are assembled to create a complete infiltration, attenuation or storage system. NOTE Non load bearing component(s) can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, thermoforming and low-pressure injection moulding.

This document specifies requirements and gives recommendations for assessment of the service environment, and the selection of metallic materials used in oil and gas production in H2S-containing environments, where the failure can pose a risk to the functionality of the equipment, to the health and safety of the public and personnel or to the environment. This document is not intended for application to equipment for carbon capture, utilisation and/or storage (CCUS, CCS) or downstream oil and gas (for downstream applications see ISO 17945/NACE MR0103), but the guidance and principles can be applied by the equipment user for these applications. This document addresses the selection of carbon and low alloy steels, cast irons, corrosion-resistant alloys and other alloys for resistance to damage mechanisms that are a consequence of H2S, or which are exacerbated by H2S. This includes sulphide stress cracking, hydrogen-induced cracking, stepwise cracking, stress-oriented hydrogen-induced cracking, soft-zone cracking, galvanically induced hydrogen stress cracking and stress corrosion cracking. Some of these mechanisms can also occur in environments that do not contain H2S, but these are not included in the scope of this document. These are not included in the scope of this document. Materials with established service limits, or which have a successful history of application are listed. A path for qualifying and accepting materials that are not listed is described in ISO 15156-3. NOTE H2S can also influence degradation mechanisms other than cracking, including general and localized corrosion. This document is intended primarily for equipment users and other parties that select and accept materials and equipment for service in H2S-containing environments. It stipulates when materials need to be specified to be in conformance with ISO 15156-1 or qualified in conformance with ISO 15156-3. All oil and gas production equipment categories handling H2S-containing fluids are within the scope of this document, including but not limited to: a) drilling, well construction, and well-servicing equipment; b) wells including subsurface equipment, gas lift equipment, wellheads, and tree equipment; c) flow-lines, gathering lines, field facilities, and field processing plants; d) water-handling, injection and disposal equipment; e) gas-handling and injection equipment including those used for CO2 enhanced oil recovery; f) natural gas treatment plants (for gas sweeting plants see also API RP 945); g) transportation pipelines for liquids, gases, and multi-phase fluids. Exclusions to the scope of this document are given in Table 1.

 

This document specifies the definition and classification of steels. It defines the term "steel" (see clause 3) and it classifies the steel grades as main criteria by the chemical composition into non-alloy, low-alloy and high-alloy steels. Micro-alloy steels are a subclass of low alloy steels and stainless steels are a subclass of high-alloy steels.

It provides guidance on methods for survey and monitoring unionid mussel populations and the environmental characteristics important for maintaining populations in favourable condition. The document is based on best practice developed and used by unionid mussel experts in Europe, and describes approaches that individual countries have adopted for survey, data analysis and condition assessment. Standard methods for restoring populations are not within the scope of this document.
