ActiveTechnical specification for cathodic protection of steel well casings
钢质井套管阴极保护耐蚀作业技术规范
Application Summary AI generated
This standard specifies the technical requirements for cathodic protection systems applied to steel well casings to prevent external corrosion. It is primarily used in the oil and gas industry for protecting the outer surfaces of casings in vertical and directional wells, covering design, installation, operation, and maintenance procedures. The standard applies to both onshore and offshore well construction and production operations where buried or submerged steel casings are exposed to corrosive environments.
