EN 13480: Standard for metal industrial pipelines, which regulates the design, manufacture, installation and inspection of pipelines, and is widely used in the construction of oil and gas pipelines in Europe.

DNV Standards

DNV-OS-F101: Standard for submarine pipeline systems, which provides detailed technical requirements and specifications for the design, material selection, manufacture, installation and inspection of submarine pipelines, and takes into account the particularity of the submarine environment, such as the effects of seawater corrosion, marine biological attachment, and current impact on pipelines.

DNV-OS-C401: Corrosion protection standard for offshore structures, which gives specific technical indicators and construction requirements for anti-corrosion coatings and cathodic protection of offshore oil and gas pipelines, ensuring that pipelines have good anti-corrosion performance in harsh marine environments.

API Standards

API RP 1104: Pipeline welding standards, which comprehensively regulates the process, welder qualifications, and weld quality control of pipeline welding, is an important basis for the welding construction of oil and gas pipelines, helping to ensure welding quality and reduce welding defects and safety hazards.

API 570: Pipeline inspection specifications, applicable to the inspection, maintenance, modification and renewal of operating oil and gas pipeline systems, provides technical guidance for regular inspection and maintenance of pipelines to ensure the safe operation of pipelines.
