DIN 2470-1 and DIN 2470-2 are the core standards for the design of steel natural gas pipelines in Germany, which respectively specify technical requirements for different pressure levels. DIN 2470-1-1987 specifically applies to steel pipelines and fittings for public gas supply services that allow a working pressure not exceeding 16 bar (1.6 megapascals), covering material, size, and safety requirements for pipeline systems, but does not apply to pipelines in non-public gas supply fields such as chemical engineering. DIN 2470-2-1987 supplements specifications for pipeline strength, welding processes, and accessory selection at higher pressures for high-pressure gas delivery scenarios where the allowable working pressure exceeds 16 bar.

Technical requirements and material specifications
This series of standards provides detailed requirements for the material properties, processing technology, and testing methods of steel pipes. For example, pipelines need to use steel that meets specific strength grades, welding processes need to meet DVGW (German Gas and Water Industry Association) standards (such as G 459, G 462/I, etc.), and non-destructive testing of weld quality is required. In addition, the standard also specifies the requirements for wall thickness calculation, pressure resistance testing, and internal and external anti-corrosion coatings of pipelines to ensure safety and reliability during long-term operation.
Association with other DIN standards
The DIN 2470 series, together with multiple German industrial standards, has built a complete pipeline technology system. For example, DIN EN 12732: The 2014 "Functional Requirements for Welded Steel Pipes in Natural Gas Infrastructure" supplement the general functional specifications for welded steel pipes, while standards such as DIN 17175 and DIN 17176 provide specific technical requirements for special scenarios such as heat-resistant seamless steel pipes and hydrogen delivery pipes.
