What material is API 5C? Can it be replaced with domestic 20# just like SA 106B?
This model should refer to the pipeline standard number rather than the material number. The poster may wish to refer to API 5L – the standard set by the American Petroleum Institute (PSL1, PSL2), and GB/T9711 – the Chinese standard (GB/T9711.1, GB/T9711.2). Purpose: Used for transporting oxygen, water, and oil in the petroleum and natural gas industries； It can also be used in infrastructure construction, the beautification of garden paths, drainage systems, the construction of steel hooks in factories, and high-voltage power towers.
So, does the API 5L standard have a material that is similar to 20#?
API 5C is not a material standard; it is a standard for inspection, maintenance, and calculation, used in drilling sites
Refer to the **standards** based on your intended use, and then choose the appropriate material
