标准摘要
[中文适用范围]： ISO 15589 的这一部分规定了 ISO 13623 中定义的陆上管道阴极保护系统的安装前调查、设计、材料、设备、制造、安装、调试、操作、检查和维护的要求并给出了建议。 用于石油和天然气工业。 ISO 15589的本部分适用于陆地上埋地碳钢和不锈钢管道。 它还适用于受陆上阴极保护装置保护的海上管道段的登陆。 ISO 15589 的这一部分也适用于对现有管道系统进行的改造、修改和维修。 注：有时存在阴极保护无效或仅部分有效的特殊情况。 这些条件可能包括高温、涂层脱落、隔热涂层、屏蔽、细菌侵袭和电解液中的异常污染物。 [外文原描述]： ISO 15589-1:2015 specifies requirements and gives recommendations for the pre-installation surveys, design, materials, equipment, installation, commissioning, operation, inspection, and maintenance of cathodic protection systems for on-land pipelines, as defined in ISO 13623 or EN 14161 for the petroleum, petrochemical, and natural gas industries, and in EN 1594 or EN 12007‑1 and EN 12007‑3 used by gas supply industries in Europe. All contents of this part of ISO 15589 are applicable to on-land pipelines and piping systems used in other industries and transporting other media such as industrial gases, waters, or slurries. ISO 15589-1:2015 applies to buried pipelines, landfalls of offshore pipeline sections protected by on-shore based cathodic protection installations, and to immersed sections of on-land pipelines such as river or lake crossings. ISO 15589-1:2015 specifies requirements for pipelines of carbon steel, stainless steel, cast iron, galvanized steel, or copper. If other pipeline materials are used, the criteria to apply are defined under the responsibility of the pipeline operator. ISO 15589-1:2015 does not apply to pipelines made of reinforced concrete for which EN 12696 can be applied. NOTE Special conditions sometimes exist where cathodic protection is ineffective or only partially effective. Such conditions can include shielding (e.g. disbonded coatings, thermal-insulating coatings, rocky soil, etc.) and unusual contaminants in the electrolyte.
